With a solid reputation for reliability, quick delivery, and competitive pricing, Chuck Metals is a top choice for Stainless Steel 431 hexagonal bars in the area.
Stainless Steel 431 (UNS S43100) is a martensitic stainless steel alloy that contains about 15.0–17.0% Chromium, 1.25–2.5% Nickel, and a maximum of 0.20% Carbon. It boasts high tensile strength of up to 930 MPa and a yield strength around 690 MPa, along with good toughness after heat treatment. Depending on the temper, its hardness ranges from 24 to 40 HRC, providing excellent fatigue and impact resistance. While it has moderate corrosion resistance, particularly in marine and mildly acidic environments, it also offers good machinability and polishability, making it perfect for high-stress mechanical components.
