PRATAP STEEL INDUSTRIES is one of the well-known exporter and distributor of Duplex S31803 / S32205 Fasteners (Washers), which has shown good formability in a variety of fabrications. Duplex S31803 Flat Washers is a variant stainless steel alloy that is primarily used in the oil and gas industry, particularly for offshore platforms, heat exchangers, structural components, and architectural components. The temperature range of Duplex S32205 Lock Washers is typically listed as -50 Degree C to 300 Degree C (-58 Degree F to 572 Degree F); outside of this range, its performance characteristics degrade. Duplex S31803 Sealing Washer is somewhat more difficult to machine than the 300 series austenitic stainless steels, where higher cutting forces are required and more rapid tool wear is typical. Specifically, the micro – components of Duplex S32205 Split Washers experience precipitation with prolonged exposure to high temperatures, and ductility suffers with immersion in extremely cold environments. Duplex S31803 Slot Washers for over 80 % of the total usage of Duplex stainless steels throughout the world is because of its superior workability as well as corrosion resistance. Along with very high tensile and yield strength ratings, Duplex S32205 Machine Washers resists stress corrosion cracking extremely well and is pitting resistant, highly weldable, and very versatile. We recommend a maximum hot forming temperature of these Duplex S31803 Star Washer between 2010 Degree F and 2100 Degree F (1100 Degree C to 1150 Degree C).
