Stainless Steel 430
Material Data Sheet
Stainless steel grade 430 is a non-hardenable steel containing straight chromium and belongs to the ferritic group of steels. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. It can be used in certain chemical applications due to its resistance to nitric acid.
