Ubique Alloys Pvt. Ltd is a distinguished exporter of Duplex Steel UNS S31803 Nuts & Duplex Steel UNS S32205 Nuts, which prevents embrittlement and sensitization. Duplex Steel UNS S31803 Hex Head Nuts has outstanding corrosion resistance and good aqueous corrosion resistance. Duplex Steel UNS S32205 Square Nuts is very ductile and has good weldability enabling its widespread usage in many applications. Duplex Steel UNS S31803 Lock Nuts has much better creep strength at elevated temperatures than other austenitic stainless steel grades. Duplex Steel UNS S32205 Eye Nuts is suitable for continuous service at temperatures up to 2100 Degree F (1150 Degree C) and intermittent service at temperatures up to 2000 Degree F (1090 Degree C). Duplex Steel UNS S31803 Wing Nuts forms a tenacious scale at high temperature and is resistant to spalling and performs better in thermal cycling applications. Due to its relatively high chromium and nickel content, Duplex Steel UNS S32205 T Nuts is superior in most environments.

Because of its high chromium and medium nickel contents, Duplex Steel UNS S31803 Panel Nuts has good resistance to sulfidation and other forms of hot corrosion. Preheating is not necessary for Duplex Steel UNS S32205 Coupling Nuts, where inter pass temperature should not exceed 150 Degree C and heat treatment after welding is normally not usual. Heat from 1050 Degree C to 1150 Degree C and water quench, where this treatment for Duplex Steel UNS S31803 Dome Nuts ensures that all carbides are in solution.
