Adarsh Nickel Alloys is a trusted manufacturer and supplier of Super Duplex Steel Washers in Delhi, offering high-performance fastening solutions for demanding industrial environments. These washers are manufactured using premium-grade super duplex stainless steel to ensure superior strength, excellent corrosion resistance, and long service life. Adarsh Nickel Alloys emphasizes precision machining, accurate dimensions, and strict quality control to deliver reliable washers for critical assemblies. Super Duplex Steel Washers supplied by the company are widely valued for their durability, load-bearing capability, and consistent performance in harsh operating conditions.
Super Duplex Steel Washers are produced using alloys rich in chromium, nickel, molybdenum, and nitrogen, resulting in a balanced austenitic-ferritic structure. This composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, the material offers very high yield and tensile strength, excellent fatigue resistance, and good ductility. These properties allow the washers to maintain shape, integrity, and clamping force even under high loads and aggressive environments.
