Yasin Fasteners, which is located in Istanbul, Turkey, is a renowned producer and distributor of stainless steel 347H washers with high-temperature application needs for exceptional creep resistance and long-term strength. Made from a niobium-stabilized high-carbon version of 347 stainless steel, they are resistant to carbide precipitation. Yasin Fasteners offers 347H washers in a variety of sizes and specifications to industries like power generation, petrochemicals, aerospace, and thermal processing. All items are produced according to international standards in order to meet uniform quality and performance.
Stainless steel 347H washers have around 17–19% chromium, 9–13% nickel, and a higher carbon level (up to 0.10%) compared to common 347, which enhances their strength at high temperatures. The niobium addition stabilizes the alloy against sensitization, enabling it to withstand corrosion through intergranular attack even after welding or extended exposure to heat. These washers possess good mechanical properties and oxidation resistance in environments up to 1000°C (1832°F).
