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.
Grade 430F stainless steel is usually provided in bar form to be used in automatic screw machines.
Grade 434 has similar properties as grade 430, although it is a molybdenum-bearing version. The molybdenum content enhances its corrosion resistance.
The following sections will provide the key properties of grade 430 stainless steels coil, sheet and plate - covered under ASTM A240/A240M.
The chemical compositions of various elements of grade 430 stainless steels are tabulated below.
