Learn more about the properties of ASTM A216 Gr WCB and its benefits in this guide.

What is ASTM A216 Gr WCB?

ASTM A216 Gr WCB is a type of casting alloy made up of iron and carbon, developed to meet the demands of applications requiring high strength and excellent resistance to corrosion. This material offers superior wear and heat-resistance capabilities and is commonly used in demanding fabrication scenarios when welding operations are required.


Key Benefits of ASTM A216 Gr WCB

ASTM A216 Gr WCB offers several benefits when used in fabrication and welding operations. It is known for its superior strength, excellent corrosion resistance, and superior wear-resistance capabilities. In addition, this type of alloy is incredibly easy to work with and can be cut, machined or welded with ease. Furthermore, it provides an excellent bonding surface due to its ability to retain heat energy during welding operations.

Uses of ASTM A216 Gr WCB in the Petrochemical Industry

ASTM A216 Gr WCB is a particularly useful material in the petrochemical industry, due to its superior corrosion resistance and superior wear-resistance. This type of alloy is often used in the manufacture of vessels, pipe fittings, centrifuges, valves, pumps, and other components of machines used in oil refineries and petrochemical plants. Furthermore, it can also be used as an effective lining for tanks containing hydrocarbons or other hazardous materials.

Welding of ASTM A216 Gr WCB and Typical Welding Procedure Recommendations

Welding of ASTM A216 Gr WCB is highly effective, and welders have a few processes available to them when fabricating with this material. Shielded Metal Arc Welding (SMAW) and Gas Tungsten Arc Welding (GTAW) are the two most commonly used techniques for welding ASTM A216 Gr WCB components. For optimal results, operators should use GTAW as it provides an inert shielded environment that helps reduce chemical exposure while it also produces minimal thermal distortion compared to SMAW.
