**Stainless Steel 422 Bars** are a type of martensitic stainless steel, featuring a well-balanced mix of chromium (11.0–13.0%), molybdenum, manganese, silicon, and carbon, along with small amounts of nickel. This alloy is known for its high mechanical strength, excellent creep resistance, and good toughness at elevated temperatures. With a tensile strength ranging from 620 to 930 MPa and hardness between 35 and 45 HRC after heat treatment, it remains stable under thermal stress. The composition of this alloy also offers impressive oxidation and scaling resistance, making it ideal for long-term use in high-heat and corrosive industrial settings.
