Stainless Steel 1.4122, also referred to as X39CrMo17-1, is a martensitic stainless steel celebrated for its impressive strength and decent corrosion resistance. It typically comprises around 0.39% carbon, 16.5–18.5% chromium, and 0.8–1.3% molybdenum. This unique blend boosts its hardness, wear resistance, and toughness. The steel can undergo heat treatment to enhance its mechanical properties, achieving tensile strengths of up to 900 MPa along with good impact resistance. These features make Stainless Steel 1.4122 Flat Bars perfect for applications that demand both mechanical performance and corrosion resistance in moderately aggressive environments.
