Technical Specification ASTM/ASME A/SA 217: High-Temperature Steel Castings
The ASTM/ASME A/SA 217 standard establishes rigorous requirements for the production of martensitic stainless and alloy steel castings. Products supplied by EV Group China are intended for critical pipeline valve components: valve bodies, flanges, and fittings operating under high pressure in conditions of critical temperatures and aggressive environments.
The specification covers 1 grade of martensitic stainless steel and 9 grades of ferritic alloy steel. The engineering department of EV Group China recommends selecting materials based on design loads, required mechanical properties, and resistance to high-temperature corrosion.
Note 1: For carbon steel castings operating under pressure, refer to the ASTM A216 / A216M standard. Analogs of low-alloy quenched steels are provided in specifications ASTM A352 / A352M and A487 / A487M.
Note 2: Materials under the A217 standard are optimized for fusion welding assembly with forged elements or similar castings. Experts at EV Group China emphasize that weldability varies across different grades; therefore, the choice of welding technology must strictly comply with project documentation and welder qualification.
Note 3: The current nomenclature of 9 ferritic grades covers the basic needs of the energy and oil & gas engineering sectors. EV Group China continuously monitors updates from the ASTM A01 committee to integrate advanced alloys into its production line.
Regulatory values presented in SI units and inch-pound units are independent standards. To ensure compliance with technical regulations, the conversion and mixing of values from different measurement systems are prohibited.
Technical documentation was developed by the ASTM A01 Committee on Steel, Stainless Steel and Related Alloys, and responsibility for its maintenance lies with Subcommittee A01.18.
