Product Information
S31803 (COLDUPLEX) is a standard grade of duplex stainless steel based on 22% chromium and 5% nickel. Often referred to as Alloy 2205, this material is the most widely used duplex grade due to its combination of very good general corrosion resistance and high strength. However, it is not generally suitable for use at temperatures above 300°C due to precipitation of brittle micro-constituents, nor below -50°C because of a ductile-to-brittle-transition.

Product Information
The (UNS S32205) grade is a restricted-chemistry version that maintains chromium, molybdenum, and nitrogen at higher levels than the (UNS S31803) composition. It is composed of between 21% to 23% chromium, 4.5% to 6.5% nickel, 5% to 3.5% molybdenum, 2% manganese, and 1% silicon, with the balance being iron. 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.

32750
Product Information
S32750 is the standard grade of super-duplex stainless steel based on 25% chromium, 7% nickel and significant additions of molybdenum, manganese and nitrogen. As with many of the duplex grades, S32750 also offers high strength and excellent resistance to chloride stress corrosion cracking, while the molybdenum and nitrogen levels enhance the pitting, crevice and general corrosion resistance.
