🔵 Description:

 

The main components of 202 stainless steel pipes are alloy elements such as chromium, nickel, manganese, and silicon, among which the chromium content is relatively high, generally between 17% and 19%.

 

- Features of  202 Stainless Steel Pipe: 

 

202 stainless steel pipes have very good corrosion resistance and are particularly suitable for use in atmospheric and moderately corrosive environments.

 

202 stainless steel pipes also have good oxidation resistance and high temperature resistance. They can withstand pressure at high temperatures without bending or damage.

 

- What is 202 stainless steel?

 

202 stainless steel is a variant of the 200 series stainless steel category, and its national standard name is 1Cr18Mn8Ni5N. 200 series stainless steel belongs to low-nickel high-manganese steel, with a nickel content of about 5% and a manganese content of about 8%. It is a nickel-saving stainless steel.

🔵 201 VS. 202 Stainless Steel :

 
When comparing 201 and 202 stainless steel, despite the similar appearance and use in various applications, there are several key points to consider that differentiate the two types.

 

🔸Composition:

 

  • 201 Stainless Steel: This alloy contains less nickel (about 4-5%) and manganese (7-9%). It also has a slightly higher nitrogen content.

 

  • 202 Stainless Steel: Type 202 has a higher nickel content (about 4-6%) and slightly higher manganese content (7.5-10%) than Type 202.

 

🔸Properties:

 

  • Corrosion Resistance: Both 201 and 202 have moderate levels of corrosion resistance, but 202 may be slightly more resistant to corrosive environments due to its higher chromium and manganese content.

 

  • Strength: The increased nitrogen content in 201 stainless steel can sometimes result in a slightly higher yield strength than 202 stainless steel, but the difference is usually not significant.

 

  • Machinability: Both grades exhibit good machinability, but specific characteristics may vary depending on the precise chemical composition and processing processes undergone.
