Stainless steel alloys usually have a chromium content of a least 10%. Stainless steel base metals are grouped primarily into three classes depending on their crystal structure; austenitic (such as 302, 304, 308, 316, etc.), martensitic (such as 410, and 416), and ferritic (such as 409, and 430.). Austenitic grades are also available with a [...]
