Stainless Steel 442 Nuts are crafted from ferritic stainless steel, which contains about 18% chromium and small amounts of molybdenum, giving them remarkable oxidation and corrosion resistance. This alloy boasts high tensile strength, good creep resistance, and stability at elevated temperatures. The mechanical properties include a tensile strength of approximately 450 MPa, yield strength of 280 MPa, and hardness reaching up to 200 HB. SS 442 retains its mechanical integrity even in high-temperature settings, making it suitable for thermal applications while providing excellent dimensional stability and wear resistance.
