Our Stainless Steel 347H Washers are made from a high-carbon variant of stabilized austenitic stainless steel, featuring 17–20% chromium, 9–13% nickel, and columbium (niobium) to enhance stability. The increased carbon content in 347H boosts its resistance to high-temperature creep, while niobium helps prevent carbide precipitation during welding. These washers excel in resisting oxidation and intergranular corrosion, making them suitable for continuous use at temperatures reaching up to 1010°C (1850°F). They retain their strength and stability in both high-heat and corrosive settings.
You’ll find Stainless Steel 347H Washers commonly used in heat exchangers, pressure vessels, boilers, furnace components, and exhaust systems. Their ability to maintain structural integrity in extreme conditions makes them vital in the chemical, refining, and aerospace sectors. These washers ensure secure load distribution for bolted joints that face thermal cycling, vibration, and stress. With their impressive combination of thermal resilience, corrosion resistance, and mechanical strength, Stainless Steel 347H Washers are a trustworthy choice for critical high-temperature fastening needs.
