Where does Rolex s 904L steel come from?

Briefly talk about the advantages and disadvantages of 904L steel.

Rolex is the only brand in the watch industry that uses 904L steel on watches, you must know that even the famous Patek Philippe uses only 316L steel, which illustrates the uniqueness of Rolex, the composition of the two steels has been analyzed in previous articles, but not here, because of the higher alloy content of 904L steel and the addition of a small amount of copper, 904L steel is much stronger than 316L in corrosion resistance and wear resistance. This is its greatest advantage.

The disadvantages are also easy to draw, high strength is not easy to process, its polished gloss makes many business watches can not be applied, and 904L steel is prone to allergies, which is the reason why many watch manufacturers do not use it.

904L steel produced from**? (emphasis added).

Rolex has been kept secret from the outside world, and after research, the first clue comes from an old Rolex advertisement, ** the advertisement is a prototype of a watch case that has just been cut from a single piece of steel, with the book "Some Steel is More Ambitious", and the bottom begins to claim the advantages of 904L steel, and mentions that it is a raw material imported from Sweden.

Rolex 904L steel source? Reveal the secret of super steel's top business and material background.

Then it can be determined that 904L steel must come from Sweden, yes, Sweden is a steel power, there are many steel mills, and Sweden was one of the poorest and most backward agricultural countries in Europe in the mid-19th century. Industrial development mainly relies on forest resources to develop the pulp industry and paper industry, relying on hydropower resources to develop hydroelectric power, trust iron ore resources, and develop mining and iron and steel industries.

Sweden iron ore reserves of 4 billion tons, and mostly rich ores, the use of sufficient high-quality raw materials, Swedish steel does not engage in low-level repeated construction, the main target is special steel, high-quality steel. Sweden produces more than 5 million tonnes of steel per year, one third of which is special steel, which is unique in the world.

After mixing in the bezel for a long time, I slowly came into contact with some internal information, and now it is more certain that Rolex's 904L steel block is provided by the Swedish Sandvik company (Chinese name: Sandvik company), and then polished in Switzerland, and 904L is more expensive than 316L steel when cutting, so even the machine is specially customized by Rolex from Germany.

In addition to Rolex 904L steel blocks, Sandvik also supplies 316L steel blocks to a number of other Swiss watchmakers. However, the 904L steel block is not listed in the Sandvik company's product catalog, and it is believed that it is exclusively supplied by the agreement, and other watchmakers are not willing to pay a high amount of money for it, and have to change the production line, etc. This is the unique craft of labor watchmaking.

Tips for buying watches: 316L steel can only be used as a scalpel, but 904 steel can be implanted into the human body with various supports, and its corrosion resistance and various other properties are significantly higher than that of 316L steel. The price of 904L steel is also more than 3 times higher, not blowing or black, although 904L steel is good, but not a god, in the watch 316L steel is actually enough.

Later articles will reveal the pink gold composition of Rolex, as well as platinum watches.

Rolex's 904L steel is made in Sweden. The material of this steel is very good, with many characteristics such as corrosion resistance and high temperature resistance.

The steel used by Rolex must have come from Sweden, a steel powerhouse. Sweden has iron ore reserves of up to 4 billion tons, and most of them are rich ores.

Rolex has always kept it a secret, but according to an old Rolex advertisement, it can be seen that Rolex's 904L steel is made in Sweden.

Swiss high-end luxury brands in the selection of materials generally use *** as a material, Vacheron Constantin, Patek Philippe and other top brands produce a batch of steel watches everyone will feel very strange, this year's SIHH Vacheron Constantin ** complex steel watch came out, causing major ** scramble to report.

In fact, the two metals are essentially not much different, but the proportion of nickel, chromium, and molybdenum metal is somewhat different, the most important of which is that there is copper in 904L steel and no copper in 316L steel. In this way, 904L steel is much stronger than 316L steel in terms of corrosion resistance and wear resistance. The two parts that are most susceptible to wear and tear in our daily watch wear are the strap and the case, and from this point of view, 904L steel is better than 316L steel.

Isn't that enough to say that 904 steel is better? Why don't other brands use this significantly better steel and instead use 316L steel? This is because 316L steel has a huge advantage over 904L steel, that is, it is not easy to be allergic, so 316L steel is widely used in the food and medical industries, that is to say, from the perspective of safety, 316L steel is better than 904L steel.

That is to say, the two kinds of steel have their own merits, the reason why Rolex uses 904 steel, the main reason is marketing, Rolex as a leader in the marketing of the watch industry, well versed in various marketing concepts (the originator of hunger marketing), Rolex uses 904 steel The main purpose is for marketing, as a luxury brand, Rolex knows that only with other people's differences can get the greatest degree and attention.

And 904L steel is not of great practical significance to ordinary cousins, and it can even be said that it has no use. Why? To give you the simplest example, have you ever seen 316L steel that has been corroded by seawater?

If you have to show the super corrosion resistance of 904L, it is only in sulfuric acid. To put it simply, 316L steel is enough to resist all the corrosives in our daily life, and 904L steel is not needed at all.

In summary: the main reason why Rolex uses 904L steel is the brand's self-marketing, which invisibly enhances the added value of its own brand by being different from others.

Fame aside, Rolex watches have always been pragmatic and of excellent quality. Six words: reliable, precise, durable.

In contrast to Patek Philippe, which pursues the highest level of craftsmanship and complications, Rolex has always aimed for a "utility watch". Don't do bells and whistles, such as tourbillons, minute repeaters, perpetual calendars and other super complications, because then the movement is more prone to problems. Secondly, Rolex rarely even makes ultra-thin watches, and most models are kept at about 13mm thick, also to ensure the quality of the movement and improve stability.

Instead, Rolex prefers to invest in R&D to improve durability, such as the development of various specialty metals that are durable and less susceptible to oxidation.

Rolex is a brand that uses 904L steel in large quantities. 904L steel is different from the common 316L steel in that it has strong corrosion resistance and hardness. Not only that, but because the steel purity of Rolex's 904L steel is very high, the polish is very good.

Therefore, 904L steel is also known as "labor steel".

Most importantly, Rolex takes the quality of its products very seriously. Every Rolex watch is polished, machined and assembled in its own Swiss factory. Moreover, all Rolex movements have been chronometer certified, of course, this is not an ordinary certification, known as "Super Chronometer Certified", with an error standard of 2 seconds per day.

Thirdly, Rolex has a high value retention rate and perfect after-sales service. Neither relying on *** nor scarcity, it can still achieve the world's first value retention rate! You say Rolex relies on "hunger marketing" to ensure value retention?

In fact, it is not so simple, Patek Philippe produces less than 20,000 pieces a year, and each piece is used, so it is not unusual to maintain its value.

However, compared to Rolex, which produces one million pieces a year, and most of them are steel watches, and most of them are worth only about 80,000 yuan, but its second-hand discount rate is maintained at around 9% off (perfect condition) all year round.

Even a Rolex, which was originally priced at 70,000 yuan, can now be bought for only 140,000 yuan! Say it out that there is a face (qian) child (duo)!

Of course, there is such a high retention rate, which is also thanks to Rolex's after-sales service, Rolex provides a 5-year warranty for its products, not to mention the short warranty period. Every repaired Rolex watch is treated with the utmost care and factory data is restored to its peak again!

Rolex is blown out, in fact, 904 steel is not high-tech. Which fake B factories in Guangzhou also make 904, and there are other watches that also use 904 steel. It is a fool to worship 904 steel as a god.

Omega is better with GH984 superalloy steel, and people's advertisements are not foolish. As we all know, Rolex relies on auction price and bragging and starvation marketing to raise the ** and harvest a large number of leeks, which is sad.

Although this steel can be welded using a common welding process, the appropriate welding methods are manual arc welding and tungsten argon arc welding.

When manual arc welding is used to weld plates not more than 6 mm, the diameter of the electrode is not more than mm; When the plate thickness is greater than 6 mm, the diameter of the electrode is less than mm. When heat treatment is required after welding, it can be heated at 1075-1125 degrees Celsius and then cooled quickly. The filler metal used for tungsten argon arc welding can be used with the same material electrode, and the weld must be pickled and passivated after welding.

Summary. Hello, glad to answer for you. <>

The official Rolex 904L** is around 60,000 to 200,000. Rolex 904L is not a specific product, but refers to a special material used by Rolex - 904L stainless steel. The material is resistant to corrosion and abrasion, and is widely used in Rolex watch manufacturing.

Because there are so many types of Rolex watches, there are so many differences. To be sure, 904L stainless steel is more expensive than regular stainless steel, and some Rolex watches with this material will cost slightly more as a result. <>

Hello, glad to answer for you. <>

The official Rolex 904L** is around 60,000 to 200,000. Rolex 904L is not a specific product, but refers to a special material used by Rolex for Yu Hong, 904L stainless steel. The material is resistant to corrosion and abrasion, and is widely used in Rolex watch manufacturing.

Because there are so many types of Rolex watches, there are so many differences. However, it is certain that 904L stainless steel is more expensive than ordinary stainless steel, and some Rolex watches with this material will cost slightly more as a result. <>

Dear, there are still questions to be raised, this vertical let the book continue to answer for you <>

All Rolex just took to 904 Gang. All Rolex watches use 904 steel, which is more corrosion-resistant and durable than ordinary 316 steel, so the cost of 904 steel is also higher than that of 316 steel, and the quality is better.

Rolex is the only company that uses 904L stainless steel for all steel models, which is why 904 stainless steel is also known as Laosteel.

Identification methods

Rolex watches are Swiss-made luxury watches that are designed, made and traditional. Its performance includes fully automatic, single calendar, double calendar, waterproof, dustproof, etc., and the workmanship is excellent, especially the dial, handle and strap, and engraved crown are the hallmarks of its high quality.

Because brand-name watches use advanced equipment and high-quality materials in manufacturing, they achieve fine processing and high finish. A real Rolex watch, both in terms of workmanship and text, is very fine and has a perfect feel, which is an important aspect of distinguishing the authenticity from the fake.

From the outside, the Rolex case is fine, the strap, the crown, and the English text are clear and complete, while the imitation case is rough and the text is slightly blurred. In particular, the bottom and cover teeth are very fine and clear, clean and three-dimensional, while the imitations are rough and have no three-dimensional sense, and are generally relatively shallow. In terms of weight, the real one feels heavier in the hand, and the fake one is much lighter.

As far as the 18K gold Rolex case and strap are concerned, the genuine products are generally from new to old, and the quality and color remain unchanged, and the imitations have 14K gold or lower K gold or 18K gold plated, but after a long time, they will change back to their original colors. The starry Rolex and the diamonds set in the watch are real, while the imitation diamonds are fake.
