Technical Features of the ASTM A216 / ASME SA 216 Specification
The ASTM/ASME A/SA 216 standard sets stringent requirements for the production of carbon steel castings intended for use in equipment operating under pressure at elevated temperatures. Products supplied by EV Group China fully comply with these regulations, ensuring high reliability for pipeline valve components, including flange connections, valve bodies, and fittings.
Alloys regulated by this standard possess optimal fusion weldability and high compatibility with forged steel parts, which is critical during the installation of complex engineering systems.
Classification and Marking of Steels
The specification identifies three primary grades of steel: WCA, WCB, and WCC. The selection of a specific grade depends on design loads, calculated operating temperatures, and required mechanical characteristics. EV Group China engineers recommend referring to the data in the table below to ensure compliance with project parameters.
| Steel Grade | Application | Temperature Range |
|---|---|---|
| WCA | General engineering | High temperatures |
| WCB | Pipeline valves | High temperatures |
| WCC | Specialized castings | Extreme loads |
Important note: The values presented in SI units and inch-pound units are independent standards. To avoid errors during design and ordering from EV Group China, strictly adhere to one chosen system of measurement without mixing them.
This specification is developed and maintained by the ASTM A01 Committee (Steel, Stainless Steel, and Related Alloys) with the direct involvement of Subcommittee A01.18 on Castings.
