Duplex Steel UNS S31803 Nuts

About Duplex Steel UNS S31803 Nuts

Duplex Steel UNS S31803 Nuts possess a unique chemical composition that gives them excellent strength and corrosion resistance. This highly alloyed stainless steel consists of chromium, nickel, molybdenum and nitrogen with a minimum PREN (Pitting Resistance Equivalent Number) of 35. It also contains roughly 21-27% chromium, 3-5% nickel, 2-3% molybdenum, and a full 0.15%-0.2% nitrogen content, making it an incredibly durable material for fastening applications in harsh industrial environments. As such, Duplex Steel UNS S31803Nuts are widely available and preferred by many because of their remarkable combination of mechanical properties and corrosion resistance, as well as their cost-effectiveness compared to other materials on the market.
