Solid copper-coated wire for submerged arc welding. Nominal composition of 1%Ni-0.5%Mo capable of achieving 90ksi (620MPa) tensile strength. Supplied to NACE MR0175 1.0%Ni maximum on request.
Applications
WB36 is a high-temperature construction steel for service up to 450°C; typical applications are below 400°C designed based on tensile rather than creep properties. It is mainly used for feedwater piping systems in place of standard carbon steels (e.g. A106 grade C) in conventional and nuclear power stations. WB36 also finds applications for headers, manifolds and fittings in power stations.
