Harsh Metalloys, located in Mumbai, India, stands out as a leading manufacturer and supplier of Stainless Steel 442 Bolts, specifically crafted for applications that demand exceptional corrosion resistance and high-temperature performance. Grade 442 is a ferritic stainless steel celebrated for its superior oxidation resistance and strength, making these bolts perfect for challenging environments. Offered in a variety of sizes and thread types, our SS 442 bolts meet international standards such as ASTM A193 and ASME. Commonly utilized in the petrochemical, power generation, and furnace industries, Harsh Metalloys guarantees robust and dependable fastening solutions that can endure thermal and chemical stresses.
Stainless Steel 442 Bolts are made from ferritic stainless steel alloys, containing about 18–20% Chromium, with low Carbon and minimal Nickel content. This unique composition enhances their resistance to high-temperature oxidation and corrosion. Typically, these bolts boast a tensile strength of around 620 MPa and a yield strength close to 310 MPa. They maintain their mechanical stability and hardness even at elevated temperatures, resisting scaling and sulfidation. While they may be less ductile than austenitic grades, SS 442 bolts provide excellent thermal fatigue resistance, dimensional stability, and durability in oxidizing and mildly corrosive environments.
