Super Duplex Gate Valves
The Alloy Valve Stockist generally supplies super duplex A182 F53, A182 F55, A890 Gr. 5A and A890 Gr. 6A gate, globe, check, ball, butterfly, plug, needle and custom made valves. Super duplex valves come according to various standards like 318LN, but are most commonly found as forged A182 F53 and the higher grade A182 F55. The newer cast grades, A995 Gr. 5A and the more noble 6A are more and more prevalent in the valve market, substituting the older norm A890Gr. 5A and 6A.
Super Duplex valves are at times denominated UNS S32205 equivalent to Sandvik`s popular 2205, whilst UNS S32750 matches the properties of A182 F53 and the universal code S32760 squares up with F55. The chemical compostion can be described as X2CrNiMoN22-5-3 or alternatively the more chrome-laden X2CrNiMoCuWN25.7.4. 1.4410, 1.4501, 1.4507, 1.4462, Super Duplex also trades under commercial designations Ferralium 255, and the similar URANUS 45N as well as the higher alloy 52N.
