Carbon Steel A216 WCB

Designations: A216 Gr WCB · UNS J03002 · ISO 3755 Gr 270-490WASTM A216 Grade WCB is the general-purpose carbon steel casting grade for pressure-containing parts at temperatures where carbon steel remains suitable. Its controlled carbon and manganese give weldability without preheat in most sections, and the standard caps residual elements so the steel responds predictably to normalizing. It is specified for valve bodies, pump casings, flanges and fittings. Kormax casts A216 WCB to order.
