440C Stainless Steel Plate/steel bar/steel coil - UNS S44004

Type 440C 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 has moderate corrosion resistance, comparable to 304. This grade of stainless steel plate can be hardened through heat treatment, but machining is preferable in the annealed condition and becomes extremely difficult once hardened.

Highest resistance can be achieved through hardening and polishing, and the properties of 440C steel make it ideal for knife blades and cutting instruments like surgical blades. This grade, once hardened, hold a sharp edge and resists corrosion, and can be polished to a near mirror finish. Its toughness and ability to resist wear makes 440C stainless steel a good choice for tools like chisels and ball bearings.
