Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Super Duplex S32750 Washers, which is often referred to as an excellent grade due to the molybdenum content. The difference between the two is the contents of chromium and nitrogen is higher in Super Duplex S32750 Flat Washers which in turn creates higher corrosion resistance as well as a longer lifespan. Super Duplex S32760 Lock Washers is composed of between 24 % to 26 % chromium, 6 % to 8 % nickel, 3 % molybdenum, and 1.2 % manganese, with the balance being iron. Also found in Super Duplex S32750 Sealing Washers are trace amounts of carbon, phosphorus, Sulphur, silicon, nitrogen, and copper.

Benefits of Super Duplex S32760 Split Washers include: good weldability and workability, a high level of thermal conductivity and low coefficient of thermal expansion, high resistance to corrosion, fatigue, high resistance to pitting and crevice corrosion, high resistance to stress corrosion cracking (especially chloride stress corrosion cracking), high energy absorption, high strength, and erosion.
Essentially, Super Duplex S32750 Slot Washer are a compromise; possessing some of the ferritic stress corrosion cracking resistance and much of the superior formability of the common austenitic stainless alloys, more cost effectively than the high nickel alloys. Super Duplex S32760 Machine Washers has the ability to withstand high temperatures and maintain strength under volatile conditions.
