Stainless Steel 904L Flat & Spring Washers are essential components in various industrial applications, known for their excellent corrosion resistance and durability. These washers are particularly suitable for harsh environments where resistance to acids and chloride-induced pitting is critical. At Vision Alloys, we manufacture these flat & spring washers to meet stringent standards, including ASTM A193, ASME SA193, and DIN 1.4539 specifications. This ensures that our products are reliable and of the highest quality, making them ideal for chemical processing, petrochemicals, and offshore oil and gas uses.
As specialized stainless steel 904L flat & spring washers manufacturers, we offer washers made from austenitic stainless steel grade 904L, known for its high nickel and chromium content, along with the addition of copper. This specific composition enhances the alloy's resistance to strong reducing acids like sulfuric acid and its general resistance to corrosion and stress corrosion cracking. The high alloying elements also provide exceptional strength and durability, making these washers suitable for heavy-duty applications. The washers are available in flat and spring types, catering to different functional requirements in various assembly and fastening tasks.
As a prominent stainless steel 904L flat & spring washers supplier in Mumbai, we provide various sizes and specifications to meet diverse industrial needs. Our stainless steel 904L spring washers are designed to maintain tension in bolted assemblies, preventing loosening due to vibrations or thermal expansion. On the other hand, the flat washers provide a stable bearing surface, distributing the load of threaded fasteners evenly. This helps reduce surface wear and extends the life of the equipment. All our washers undergo rigorous quality checks to ensure they meet international standards, providing reliable performance in critical applications.
