Stainless Steel 442 is a ferritic stainless steel known for its high chromium content, typically ranging from 18% to 23%, along with low carbon levels that boost its corrosion resistance and toughness. This unique composition gives it excellent resistance to oxidation, stress corrosion cracking, and scaling at elevated temperatures. The stud bolts made from Stainless Steel 442 offer good tensile strength, moderate hardness, and stable mechanical performance even under thermal cycling. Their ferritic structure ensures low thermal expansion and solid resistance to fatigue, making them perfect for applications that face heat and corrosive environments.
