These Stainless Steel 422 Nuts are primarily crafted from chromium, molybdenum, and carbon, with carefully controlled amounts of manganese, silicon, and nickel. As a martensitic stainless steel, Grade 422 can be heat-treated to achieve impressive hardness and excellent wear resistance. These nuts boast strong tensile and yield strength, maintain their structural integrity at elevated temperatures, and offer remarkable fatigue resistance. Their moderate corrosion resistance, combined with outstanding mechanical properties, makes them a reliable choice for applications that involve continuous stress, heat exposure, and harsh operating conditions.
