Characteristics and uses of each series of stainless steel: 200 series
200 series
a, 201
1Cr17Mn6Ni5N
SUS201
Features: It has the characteristics of acid resistance, alkali resistance, high density, no bubbles, no pinholes.
Uses: Mainly used for decorative tubes, industrial tubes and some shallow stretch products.
b, 202
1Cr18Mn8Ni5N
SUS202
Characteristics: Partial nickel is replaced by Mn and N, which has good mechanical properties and corrosion resistance. It is a new type of nickel-free stainless steel with higher room temperature strength than 304 and better oxidation resistance below 800 °C. And medium temperature strength
Uses: Mainly used for decorative tubes, industrial tubes and some shallow stretch products.
c, 2205
00Cr22Ni5Mo3N
SUS2205
Characteristics: Its Cr, Mo and N elements are relatively narrow in range, easy to reach a relative balance (ie, two phases are about half each), which improves the strength, corrosion resistance and weldability of steel, and is often used for higher performance requirements. Materials that need to be welded, such as oil and gas pipelines.
Uses: Used in refining, chemical fertilizer, paper, petroleum, chemical and other heat exchangers and cold showers and devices resistant to seawater, high temperature and concentrated nitric acid.
