This martensitic, heat-resistant stainless steel is specifically designed for tough environments where standard grades just won’t cut it. Hemi Metals ensures that these bars and rods are produced with precise dimensional accuracy, consistent composition, and top-notch metallurgical quality to meet global industrial standards. You’ll find Stainless Steel 422 Bars and Rods in power generation, turbines, mechanical components, and high-stress engineering applications. The company’s commitment to quality and performance guarantees reliable results in critical service conditions.
Stainless Steel 422 Bars and Rods are made up of 11–13% chromium, 0.2–0.3% carbon, along with controlled amounts of molybdenum, tungsten, silicon, and vanadium, all of which boost high-temperature strength and creep resistance. This martensitic alloy delivers impressive mechanical strength, hardness, and oxidation resistance, even at temperatures exceeding 500–600°C. It showcases strong fatigue performance, good thermal stability, and dependable toughness after heat treatment. While it may not be as corrosion-resistant as austenitic grades, it holds up well in high-temperature settings. SS 422 maintains its structural integrity under heavy loads, making it ideal for components that need long-term strength and wear resistance.
