Sulfide based stress corrosion crackingCorrosion resistance levels in stainless steel - RyersonIn general, martensitic stainless steels are considered moderate when it comes to corrosion resistance. Like low alloy or carbon steels, martensitic stainless steels are similar in structure to ferritic, but can be hardened or strengthened by heat treatmentwhich can also make them more brittle. This is due to the addition of carbon. The main alloying element of this family is chromium. The oil industry is a heavy user of martensitic stainless steel, as is the medical fieldprimarily for surgical equipment.
