NiWire focuses on nickel alloys and special stainless steels. In stainless steel field, our strength are super duplex stainless steels, Nitronic 60, 904L, 254SMO, 17-4PH and so on.

Main Grades

Grade Property & Application
Nitronic 60 Excellent galling resistance at high temperatures. It is commonly used for various fasteners and pins that require strength and resistance to galling.
Nitronic 50 It is a high strength and good corrosion resistant austenitic stainless steel. It has nearly double the yield strength of 304 and 316 stainless steel and has better corrosion resistance than 317L stainless steel.
Super Duplex S32760 It has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments.
Super Duplex S32750 It combines the most desirable characteristics of both ferritic and austenitic steels. SuperDuplex is used in the oil and gas industry, on offshore platforms, in heat exchangers, chemical processing equipment pressure vessels and boilers.
Duplex S31803 It is a second-generation, nitrogen-alloyed duplex stainless steel (ferritic-austenitic). It is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking.
17-4PH It is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. 17-4 PH is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
254SMO It is an austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. 254SMO offers chloride resistance superior to that of Alloy 904L Alloy 20, Alloy 825.
904L It is an austenitic special steel with high molybdenum content as well as addition of copper and extremely low carbon content. 904L provides good resistance to chloride stress corrosion cracking.
