440C-cold-rolled-stainless-steel-coil is a martensitic stainless steel with high carbon and chromium content. After heat treatment, it is capable of attaining the highest strength, hardness and wear resistance of all stainless alloys. Compared to austenitic grades, 440C-cold-rolled-stainless-steel-coil has moderate corrosion resistance, comparable to 304. This grade of stainless steel plate can be hardened through heat treatment,
