Which is better, alloy steel or stainless steel, and which alloy or stainless steel is better

Yes. Alloy is made of stainless steel with two or more substances (at least one is metal), which has a brightness close to a mirror, hard and cold to the touch, and is a relatively avant-garde decorative material, which is in line with the cool aesthetics of the metal age. Stainless steel materials are usually divided into the following according to the matrix structure

1. Ferritic stainless steel.

Contains chromium 12 30 . Its corrosion resistance, toughness, and weldability increase with increasing chromium content.

Chloride resistant. The stress corrosion performance is better than that of other types of stainless steel.

2. Austenitic stainless steel.

Contains chromium greater than 18 and also contains.

8 About nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can resist corrosion of a variety of media.

3. Austenite.

Ferritic duplex stainless steel.

It combines the advantages of austenitic and ferritic stainless steels with superplasticity.

4. Maraging stainless steel. High strength, but poor plasticity and weldability.

So alloy steel includes stainless steel.

There are standards for the classification and number of steel grades in China.

According to the composition, it is roughly divided into two categories: carbon steel and alloy steel.

According to the use, it can be divided into structural steel (such as, quenched and tempered steel, carburizing steel), tool steel (such as, measuring and cutting tool steel, hot and cold die steel, etc.), special purpose steel (such as, bearing steel, spring steel, stainless steel, etc.).

If it is used as a spring, spring steel should be used. Such as 65 steel, 70 steel belonging to carbon steel.

60Mn, etc., 65SimN, 65Si2Mn, etc., which belong to alloy steel. Spring steel is used as a spring, making the best use of things, not only has good performance, fatigue resistance, but also has a high life. The processing performance and service performance are better than other steel grades.

Hello dear. Your question is answered as follows. Generally, stainless steel is good.

The biggest difference between alloy and stainless steel is the difference in hardness, price, surface treatment, etc.; The hardness of the alloy is lower than that of stainless steel, the price of the alloy is cheaper than that of stainless steel, and the surface treatment of the alloy is richer than that of stainless steel. 1. The hardness of the alloy is lower than that of stainless steel: both take a representative for example, the hardness of 6061-T6 alloy is 47HRB, and the hardness of 304 stainless steel is 92HRB.

2. The price of alloy is cheaper than stainless steel: the material of the alloy is mainly aluminum, with a small amount of manganese and other metals, and the main material of stainless steel is iron; The **** of 6061 alloy is about 18rmb kg, and the **** of 304 stainless steel is about 28-30rmb kg; There is also the density of the alloy is about 2700kg mm 3, and the density of stainless steel is 7900kg mm 3, it is obvious that stainless steel is much more expensive than the alloy. 3. The surface treatment of alloy is richer than that of stainless steel

The surface treatment of alloy includes spraying, electrophoresis, anodizing, etc., while the surface treatment of stainless steel generally only has the surface color whitening treatment, so more often the alloy can play a more aesthetic role. 4. The surface treatment of the alloy is not done well, and there will be oxidation and stains after a period of use, and the surface treatment of stainless steel is relatively simple, so the stability is better, but the later maintenance will also cause rust. Summary:

The construction cost of stainless steel is higher than that of alloy, so there is no shortage of money or public works are basically made of stainless steel, and the owners of the home pay more attention to aesthetics to choose alloy.

Summary. 1. All are good, because their uses are different, there is no better difference, mainly depending on what is used for use, and the material is selected according to the use of the use. 2. Stainless steel is expensive, and aluminum alloy is cheap.

3. The hardness of stainless steel is higher than that of aluminum alloy. 4. In terms of surface treatment, aluminum alloys are more abundant, including electrophoresis, spraying, anodizing, etc., and stainless steel is less. 5. Aluminum alloy with poor surface treatment will oxidize after a long time and will have marks; Stainless steel is relatively better, but the composition is not up to standard or the maintenance is careless, and it still rusts.

Which is better, stainless steel or aluminum alloy.

1. All are good, because their uses are different, there is no better difference, mainly depending on what is used for use, and the material is selected according to the use of the use. 2. Stainless steel is expensive, and aluminum alloy is cheap. 3. The hardness of stainless steel is higher than that of aluminum alloy.

4. In terms of surface treatment, aluminum alloys are more abundant, including electrophoresis, spraying, anodizing, etc., and stainless steel is less. 5. Aluminum alloy with poor surface treatment will oxidize after a long time and will have marks; Stainless steel is relatively better, but the composition is not up to standard or the maintenance is careless, and it still rusts.

The difference between aluminum alloy and stainless steel There are many aluminum alloy and stainless steel products in life, such as our common pots, basins, doors and windows, etc. The biggest difference between them is that aluminum alloy is generally lighter in weight and dull in color, while stainless steel is heavier and brighter in color, in addition to them, they are also different in terms of hardness, performance, surface, use and so on. 1. Different stainless steel is expensive, and aluminum alloy is cheap.

2. The density of aluminum alloy with different hardness is low, but the strength is high, close to steel, and the plasticity is good; Stainless steel is a nickel-chromium alloy that has a higher hardness than aluminum alloy. 3. Different high-temperature resistance: stainless steel can withstand high temperature, with a melting point of 1200-1500 degrees Celsius; Aluminum alloys cannot withstand too high temperatures, with a melting point of 500-800 degrees Celsius.

4. Surface treatment: Different stainless steel surface treatments include surface brightness treatment, surface whitening treatment, and surface coloring treatment; Aluminum alloy treatment includes electroplating, spraying, anodizing, etc. 5. Different stainless steels for industrial applications have heat resistance, oxidation resistance, good forming properties and good weldability, and can be used as ultra-high strength materials in the nuclear industry, aviation and aerospace industries; Aluminium alloys are used to process parts that require good formability but do not require high strength, such as chemical products, food industry equipment and storage containers, printing plates, nameplates, reflectors, etc.

Stainless steel and alloys, generally stainless steel is better.

The biggest difference between alloy and stainless steel chain is the difference in hardness, price, surface treatment, etc.; The hardness of the alloy is lower than that of stainless steel, the price of the alloy is cheaper than that of stainless steel, and the surface treatment of the alloy is richer than that of stainless steel.

Differences between alloy and stainless steel:

1. The hardness of the alloy is lower than that of stainless steel: both take a representative for example, the hardness of 6061-T6 alloy is 47HRB, and the hardness of 304 stainless steel is 92HRB.

2. The price of alloy is cheaper than stainless steel: the material of the alloy is mainly aluminum, with a small amount of manganese and other metals, and the main material of stainless steel is iron; The **** of 6061 alloy is about 18rmb kg, and the **** of 304 stainless steel is about 28-30rmb kg; In addition, the density of the alloy is about 2700kg mm

3, and the density of stainless steel is 7900kg mm 3, it is obvious that stainless steel is much more expensive than the alloy. 3. The surface treatment of the alloy is richer than that of stainless steel: the surface treatment of the alloy includes spraying, electrophoresis, anodizing, etc., while the surface treatment of stainless steel is generally only whitening of the surface color, so more often the alloy can play a more beautiful role.

For aluminum alloy and stainless steel, aluminum alloy is better in terms of processing and treatment.

Reason: Aluminum alloy has low density, high strength, more than high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry, second only to stainless steel.

**Stainless steel is expensive, aluminum alloy is cheap, stainless steel hardness is higher than aluminum alloy, aluminum alloy is more abundant in surface treatment, including electrophoresis, spraying, anodizing, etc., stainless steel is less, aluminum alloy with poor surface treatment will oxidize after a long time, there will be marks, stainless steel is relatively better, but the composition can not meet the standard or the maintenance is still rusty, stainless steel bad manufacturers are more, mainly in the material thickness, composition and other aspects of cutting corners.

Aluminum alloy machining

Deformed aluminum alloy can withstand pressure processing and can be processed into aluminum alloy of various shapes and specifications, mainly used in the manufacture of aviation equipment, Suisongwei building doors and windows, etc.

Shape guess change aluminum alloy is divided into non-heat treatment strengthened aluminum alloy and heat treatment strengthened aluminum alloy. Non-heat-treatable strengthened types cannot be strengthened by heat treatment to improve mechanical properties, but can only be strengthened by cold working deformation.

Aluminum alloys mainly include high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and anti-rust aluminum. Heat-treatable strengthened aluminum alloy can improve mechanical properties by heat treatment methods such as quenching and aging, and it can be divided into duralumin, forged aluminum, superduralumin and special aluminum alloys.
