430, 201, 202 stainless steel which is better

430 stainless steel is a general steel grade with good corrosion resistance, better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, heat fatigue resistance, addition of stabilized element titanium, and good mechanical properties of weld parts. 430 stainless steel is used for building decoration, fuel burner parts, household appliances, and home appliance parts. Stainless iron 430 does not contain nickel, is magnetic, and is prone to rust.

201 stainless steel has certain acid and alkali resistance, high density, polishing without bubbles, no pinholes, etc., and is a high-quality material for the production of various cases and strap covers. It is mainly used for decorative pipes, industrial pipes, and some shallow drawing products.

202 stainless steel is one of the 200 series stainless steel, and the national standard model is a series of stainless steel, which belongs to low-nickel and high-manganese stainless steel, with nickel content and manganese content of about 8%, which is nickel-saving stainless steel. 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places. It is made of high-precision automatic pipe-making equipment, through its own solution welding, rolling and forming, and welding with gas protection (inside and outside the pipe) without any metal filler.

Specific. The substitution of some or all of nickel by the elemental manganese (and nitrogen) of 201 stainless steel plate may produce lower nickel content, which is not balanced and forms ferrite. Therefore, if the ferrochrome content in 200 series stainless steel drops to 15%-16%, or even to 13%-14%, then its corrosion resistance is very poor.

202 stainless steel is one of the 200 series stainless steel, and the national standard model is a series of stainless steel, which belongs to low-nickel and high-manganese stainless steel, with nickel content and manganese content of about 8%, which is nickel-saving stainless steel.

202 is the U.S. label designation, instead of 304. Austenitic stainless steels are characterized by high phase change temperatures, so they can be used as heat-resistant steels. In order for the phase change of austenitic stainless steel, it must be heated to more than 1000, and at 350, no change in metallographic structure will occur, that is, the properties of the steel will not change fundamentally.

It will only cause expansion due to heating, but the change is not large, and it is negligible under normal circumstances, so 202 stainless steel has good high temperature resistance.

In terms of grade, 202 has one more manganese and three more nickels than 201. In practical application, in terms of utility, 202 is slightly better than 201, but most market users accept the 201 material decorative pipe with lower ** and similar actual utility to 202. 202 has slightly more chromium and manganese than 201, and the mechanics and corrosion resistance are also slightly better, but strictly speaking, the properties of these two stainless steels are not much different in nature, especially in corrosion resistance.

Stainless steel 201 contains nickel, but 201 produced by domestic manufacturers rarely adds nickel. 201 material may be more susceptible to rust than 430. 201 more decorative pipes. You can choose according to their purpose and cost.

It's all about the same, these are all low-grade goods.

304 stainless steel is good.

202 stainless steel.

It has good high temperature resistance, and the room temperature strength is relatively high, as long as it is in the environment below eight, it can have high room temperature strength and oxidation resistance, but it is easy to rust during use, 304 stainless steel not only has a beautiful surface, easy to clean, and has good wear resistance, so it is very durable, but it is more expensive than 202 stainless steel.

The best way to identify 202 stainless steel and 304 stainless steel is to use a special potion, the identification method is very simple, just drop a special potion on the stainless steel, wait for about a minute, if the place stained with the potion appears red, it means that it is 202 stainless steel, if the place stained with the potion does not change color, it is 304 stainless steel.

When distinguishing between 202 and 304 stainless steel, stainless steel can be placed into a grinding wheel running at high speed.

Observing the sparks produced by stainless steel, because 202 stainless steel contains more manganese, there are more sparks, but the manganese content of 304 stainless steel is relatively small, and the sparks are relatively bright.

This is not comparable, it mainly depends on where it is used;

304 is more expensive, and it is better to use it in the contact food industry;

202 is the most cheap stainless steel, which can not only save costs when used in the non-food industry, but also have the same strength and effect.

Is it better to use 202 or 304 for stainless steel stair handrails

Summary. In terms of chemical composition, the nickel content of 201 stainless steel is about, and 430 stainless steel sometimes contains nickel and sometimes does not contain nickel, which depends on domestic and foreign steel production standards. Both of these stainless steels have such a low nickel content that both have the potential to rust.

It is understood that 430 stainless steel is slightly more likely to rust, because it also has a nickname called stainless iron. In terms of mechanical strength, 430 stainless steel is a bit stronger than 201 stainless steel. 201 stainless steel has certain acid and alkali resistance, density, polishing without bubbles, no pinholes and other characteristics.

It is an excellent material for the production of various cases and strap case backs. It is mainly used for decorative pipes, industrial pipes and some shallow drawing products. 430 stainless steel is a general steel with good corrosion resistance, thermal conductivity is better than austenite, thermal expansion coefficient is less than austenite, thermal fatigue resistance, adding stable element titanium, and good mechanical properties of welds.

430 stainless steel is used in building decoration, oil burners, household equipment, and household appliances.
