George Metals is a reputable manufacturer and supplier located in Houston, USA, known for its top-notch Stainless Steel 1.4122 Hex Bars. These bars are designed for outstanding strength, wear resistance, and corrosion performance. Adhering to strict EN, ASTM, and DIN standards, these martensitic stainless steel hex bars provide excellent machinability and hardness after heat treatment. Stainless Steel 1.4122, also referred to as X39CrMo17-1, comes in a variety of across-flat sizes, lengths, and custom finishes to meet the rigorous demands of engineering and fabrication. Industries such as automotive, petrochemical, mechanical engineering, and power generation trust George Metals for their consistent quality and dependable supply.
Stainless Steel 1.4122 Hex Bars are martensitic chromium steels that contain approximately 16–18% chromium, 0.9–1.2% molybdenum, and 0.35–0.45% carbon. This unique alloy delivers impressive hardness and strength after quenching and tempering, with tensile strength typically falling between 700–950 MPa, along with good wear resistance. The material exhibits moderate corrosion resistance in mildly aggressive environments and maintains its shape under load. Its machinability in the annealed state is quite good, allowing for efficient processing into precision parts and components before the final heat treatment to achieve high hardness.
