Khaled Stainless, located in Cairo, Egypt, is a trusted manufacturer and supplier of Stainless Steel 442 Nuts, designed specifically for high-temperature and corrosion-resistant fastening needs. Made from high-chromium ferritic stainless steel, these nuts boast impressive resistance to oxidation, scaling, and harsh industrial environments. Khaled Stainless prioritizes precise threading, consistent hardness, and strict dimensional accuracy to adhere to international quality standards. The SS 442 nuts from Khaled Stainless find their place in power plants, furnaces, petrochemical facilities, and thermal processing industries, where durability, stability, and long-lasting performance at elevated temperatures are crucial.
Stainless Steel 442 is a ferritic stainless steel alloy that contains around 18–23% chromium and has a low carbon content, which gives it strong resistance to oxidation and scaling at high temperatures. SS 442 nuts demonstrate moderate tensile and yield strength, good hardness, and stable mechanical properties even under thermal stress. This alloy features low thermal expansion, solid resistance to sulfur-rich environments, and dependable performance in continuous service up to about 1050°C, making it an excellent choice for high-heat fastening applications.
