Something you have to know about stainless steel in China
Dec 27, 2017

Why the price of 304 stainless steel in China can vary by thousands of yuan?


Cause stainless steel has its own standard in China - GB Standard. Cr content and Ni content in GB standard are lower than ASTM A312 Standard.


What’s the difference between 2 kinds of stainless steel 304?


There is no difference in appearance. You can only calculate the concentration of stainless steel elements by the intensity of spectral color. The higher the content of chromium and nickel, the better the rust-proof performance of stainless steel. 

Below is our factory's 304 stainless steel content results.
