Super Duplex UNS S32750 combines the most desirable characteristics of both ferritic and austenitic steels. 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 due to its high chromium, molybdenum, and nitrogen level, with Critical Pitting Temperature exceeding 50°C.

The duplex microstructure gives this grade high strength UNS S32750 a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C.

Listed in NACE MR 01 75 for sour service UNS S32750 and having gained ASME Approval for Pressure Vessel applications it can be used in a wide variety of applications.

Super Duplex UNS S32550 stainless steels plates are amazingly erosion safe, work hardenable compounds. Super Duplex UNS S32550 stainless steel plate contains generally elevated amounts of chromium (somewhere around 18% and 28%) and low to direct measures of nickel (somewhere around 1.5% and 8%). The high erosion resistance and phenomenal mechanical properties of duplex stainless steels can be ascribed to their substance organization and adjusted (duplex) microstructure of roughly equivalent volume rates of ferrite and austenite.

 

In view of this duplex nature, it will show properties normal for both austenitic and ferritic stainless steels. Super Duplex UNS S32550 stainless steels plates are by and large, harder than ferritic stainless steels. Qualities of Super Duplex UNS S32550 stainless steel plates can now and again be twofold that for austenitic stainless steels.

 

Alloy UNS S32550 duplex stainless steel plate gives setting and cleft consumption resistance austenitic stainless steels in all destructive media. It additionally has high consumption and disintegration weakness properties and also bring down warm extension and higher warm conductivity than austenitic.

UNS S31803 duplex stainless steel  chromium nickel molybdenum austenitic ferritic grade. It combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparison with other stainless steel grades. UNS S31803 grade duplex resists chloride environments and sulphide stress corrosion. It is approximately double the yield strength of standard austenitic stainless steel grades. As with other duplex stainless steel specifications oxidation resistance is good at high temperature, though it is prone to embrittlement when exposed to temperatures above 300°C and is prone to embrittlement at 475°C when exposed for 2 hours only. It is also subject to embrittlement between 370-540°C when exposed over a longer period.
