202 seamless stainless steel pipe
202 seamless stainless steel pipe is including industrial pipe, capillary tube, square pipe etc. The applications of stainless steel pipe are various, they are widely used in automotive industry / petrochemical industry, including chemical fertilizer industry / water and gas and other fluid transport / equipment manufacturing.
The composition of 202 seamless stainless steel pipe:
C●0.15, Mn~7.5-10 ， P●0.06, S ●0.03, Si●0.75, Ni ~ 4.0-6.0, Cr~ 17.0-19.0
From the chemical composition, we can see the Cr composition is as high as 304 seamless stainless steel pipe, Ni composition is also much higher than 201, so its’ price is between the 201 stainless steel material and 304 stainless steel material. But its’ price is much higher than 201, so compared with 201 and 304, it is not so cost-effective and it is not so popular in the market, in the previous years, there were many customers from India, Pakistan, Bangladesh bought this kind of material, but recent years, this kind of material was not used so often.
202 seamless stainless steel pipe belongs to the 200 series, in the early development, people try to use the manganese, nitrogen to take the place of nickel to replace the 18-8 type Cr-Ni austenitic stainless steel. 18-8 type Cr-Ni stainless steel is including the 301, 302, 301, 321 which is accounted for more than 50% of the total output of stainless steel.
The comprehensive performance of its’ corrosion resistance, mechanical properties, high temperature performance, process performance and decoration is excellent, so it is widely used in the field of civilian to military and civilian building decoration. Household appliances, kitchen equipment and utensils, transportation, environmental protection, municipal construction; military aviation, aerospace, nuclear industry, ship industry; chemical, fertilizer, petroleum, textile, printing, papermaking, energy etc.
