Khaled Stainless, based in Cairo, Egypt, has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 442 Stud Bolts, specifically designed for high-temperature and oxidation-resistant industrial applications. Crafted from high-chromium ferritic stainless steel, these stud bolts are built to provide dependable clamping strength, precise dimensions, and a long lifespan even in extreme thermal conditions. Khaled Stainless adheres to strict quality control measures to guarantee accurate threading, consistent mechanical performance, and compliance with international standards. SS 442 stud bolts are commonly supplied to power plants, furnaces, petrochemical facilities, and thermal processing industries.
Stainless Steel 442 is a ferritic stainless steel alloy that contains about 18–23% chromium and has a low carbon content, which gives it remarkable resistance to oxidation and scaling at high temperatures. SS 442 stud bolts provide moderate tensile and yield strength, decent hardness, and stable mechanical performance during thermal cycling. This alloy also boasts low thermal expansion, good resistance to sulfur-rich environments, and maintains its structural integrity in continuous service up to around 1050°C, making it a great choice for high-heat bolting applications.
