Molybdenum MO: High hardness after quenching, the hardness usually reaches HRC56-58, good corrosion resistance (magnetic) and strong toughness.

If it is imported 440C stainless steel, if you make a knife, if the heat treatment is done properly, it should be able to reach HRC59-60The abrasion resistance is higher than that of 9Cr18MoV.

However, the performance of domestic 9CR18MO is significantly inferior to that of 440C stainless steel.

It's just that there are a lot of domestic knife brands known as 440C, but there are very few imported 440C that can really be used, most of them are 9Cr18, 9Cr18Mo, 9Cr18MoV mixed, and they are all known as 440 or 440C.

There are even unscrupulous manufacturers who use 8cr13 and 9cr13 to pretend to be 440c, which is even more exaggerated.

In addition, I personally believe that 440C should not be treated to HRC60 or above hardness, otherwise there will be cracking, which is not conducive to improving wear resistance. And to do HRC59, the wear resistance is relatively low.

Therefore, as a tool steel, 440C has relatively little room for improvement in wear resistance and hardness.

Personally, I prefer die steel or high-speed steel with high hardness and high wear resistance to make daily tools. If it is an occasion with high rust resistance, I would rather choose SKD11, RWL-34, BG42. Nor will I choose the 440c.

It's very good to make this thing, stainless steel can now be used in many places, and it can also be made into a beautiful, gift.

The 440C carbon content is slightly higher. But it is more troublesome to deal with than 9cr18mov. Therefore, if you buy 440c knives, it is best to choose knives from famous foreign companies.

Forget about the domestic ones. The domestic heat treatment is very low-grade. Hard, brittle knives abound.

One moment you may be able to cut the wire, but the next you will break the tip of the knife because you stab the plank. This is the common problem of domestic 440c knives. In fact, the better domestic knife manufacturers such as Handao and Handi.

Their 9CR18MOV tools are not only easy to sharpen, but also have a hardness of HRC58-59. No worse than the HRC59-60 achieved by 440C. Moreover, 9CR18MOV is the earliest commonly used stainless steel for knives.

It can be said that in terms of the maturity of production experience and production process. 9CR18MOV is more dominant. Of course, the foreign technology is mature, if it is a pure imported good knife.

Of course, it's better to choose 440c. However, there are not many imported knives that use 440c. After all, it is not easy to polish after increasing the hardness.

Relatively speaking, 9Cr18MOV has good thermal conductivity and high viscosity, which is more conducive to grinding. Personal preference. I like high-hardness knives and I'm not afraid to spend time polishing.

440c is certainly the best.

Almost 440C is relatively better material, Kunshan Longtuo has sales.

1Cr17 stainless steel belongs to ferritic stainless steel, because of its high chromium content, corrosion resistance and oxidation resistance are relatively good, but the mechanical properties and process properties are poor, and it is mostly used for acid-resistant structures with little force and oxidation resistant steel. This kind of steel can resist the corrosion of atmosphere, nitric acid and brine solution, and has the characteristics of good oxidation resistance at high temperature and small thermal expansion coefficient, etc., and is used for nitric acid and food factory equipment, and can also make parts that work at high temperatures, such as gas turbine parts.

304 belongs to austenitic stainless steel: good comprehensive performance, can resist a variety of media corrosion. Steel contains a large amount of Ni and Cr, which makes the steel in an austenitic state at room temperature.

This kind of steel has good plasticity, toughness, weldability and corrosion resistance, and has good corrosion resistance in oxidizing and reducing media, and is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment linings, transportation pipelines, nitric acid-resistant equipment parts, etc. Austenitic stainless steels are generally solution treated, that is, the steel is heated to 1050 1150 and then water cooled to obtain a single-phase austenitic structure.

The 304's tensile strength is similar to that of the 430.

1cr17 people make cutlery knives and forks, and there are more bowls.

The 304 is more versatile, but much more expensive.

If you want to eat high temperatures.

These two steels should not be considered.

310s 309s 321 436l 409l and so on, all eat high temperatures.

It is a stainless steel material.

Stainless steel refers to the steel that is resistant to weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to corrosion by weak corrosive media is often called stainless steel, and the steel that is resistant to chemical media corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media, while the latter is generally stainless steel.

The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.

9Cr18 steel is a high-carbon, high-chromium martensitic stainless steel, which has high hardness, high wear resistance, and corrosion resistance after quenching. The steel is suitable for the manufacture of plastic molds that are subjected to high wear resistance, high loads and corrosive media.

The steel belongs to the Leais steel body, which is easy to form uneven carbide segregation and affect the service life of the mold, so the hot working process must be strictly controlled during hot processing, and attention must be paid to the appropriate processing ratio.

Main properties: 1. Weldability.

The requirements for welding performance vary depending on the use of the product. A type of tableware generally does not require welding performance, even including some pot enterprises. However, the vast majority of products need raw materials with good welding performance, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.

2. Corrosion resistance.

The vast majority of stainless steel products require good corrosion resistance, like:

Class 1 and II tableware, kitchenware, water heaters, water dispensers, etc., some foreign businessmen also do corrosion resistance tests on products: heat to boiling with NaCl aqueous solution, pour out the solution after a period of time, wash and dry, weigh the weight loss, to determine the degree of corrosion (note: when the product is polished, due to the abrasive cloth or sandpaper containing Fe components, it will cause rust spots on the surface during the test).
