This post was last edited by Yunmu on 2019-2-21 at 17:17. Experts, please help me figure out what the material of the valve body for the butterfly valve below is

The first three are made of 304 stainless steel, and the last one is made of cast iron

Are you sure that 304 contains titanium?

The material of this valve body contains Ti, similar to S32169, but the Ni content is close to the lower limit.

I didn’t pay attention to the material code on the back: lol, this is SUS321

Reply #62019-02-25

I think it’s close to 321 material, 0Cr18Ni10Ti

1cr18ni9ti is a Chinese stainless steel grade, equivalent to 321
