Yasin Fasteners manufactures 442 stud bolts with different sizes and specifications for industries like power generation, automobiles, chemical processing, and furnace production. The firm makes sure that all products conform to international standards, offering long-lasting and trustworthy fastening solutions for tough conditions.
Stainless steel 442 stud bolts have around 17–19% chromium and trace amounts of molybdenum and nickel that make them more corrosion resistant and stronger. They have a ferritic microstructure, which has good stress corrosion cracking resistance and thermal fatigue resistance. The stud bolts retain strength and size stability up to about 900°C (1650°F), which makes them an ideal choice for high-temperature applications. The stud bolts have good resistance to corrosion and oxidation in mildly aggressive conditions.
