431/1.4057 Stainless Bar

431 Stainless Bar is a heat treatable martensitic, nickel-bearing grade with the best corrosion properties of all the martensitic grades. It has excellent tensile and torque strength and good toughness making it ideally suitable for shafting and bolt applications. It is not readily cold worked because of its high yield strength therefore not recommended for cold heading or bending. Grade 431 has good resistance to a wide variety of corrosive media.

Suitable for shafts, bolts, pump spindles, fasteners, fittings and structural components.
