SS 347 Washers

SS 347 Washers are niobium-stabilized stainless steel components designed to distribute load evenly and prevent loosening in bolted assemblies under heat and pressure. These washers exhibit exceptional strength and corrosion resistance in high-temperature environments, making them ideal for petrochemical, aerospace, and power generation applications. Zeron Fasteners manufactures and supplies premium-quality SS 347 Washers in various forms such as Flat Washers, Spring Washers, and Lock Washers. Their precise dimensions, durability, and resistance to oxidation ensure long-term performance even in aggressive industrial conditions.
