Request For Our Latest Prices on Stainless Steel 442 Washer in Istanbul, Turkey!
Yasin Fasteners, Istanbul, Turkey, is a trusted manufacturer and supplier of stainless steel 442 washers, specifically for applications that demand superior corrosion resistance and high-temperature strength. 442 washers are produced using a ferritic stainless steel alloy and provide adequate resistance to scaling and oxidation at elevated temperatures, making them well-suited for harsh environments. Yasin Fasteners manufactures these washers in different sizes and specifications to be used in industries like automotive, chemical process, heat treatment, and power generation. All products are made to international standards as well as specific requirements of customers for quality and durability.
Stainless steel 442 washers consist predominantly of iron with approximately 17–19% chromium and minor contents of molybdenum and nickel, which increase corrosion resistance and mechanical properties. The ferritic microstructure offers high resistance to stress corrosion cracking as well as thermal fatigue. The washers retain their strength and performance in temperatures up to approximately 900°C (1650°F) and thus are suitable for use in high-temperature settings. They have good resistance to oxidation as well as corrosion in mildly corrosive environments.
