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.<\/p>\n
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.<\/p>\n
Note 1:<\/strong> 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.<\/p>\n Note 2:<\/strong> 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.<\/p>\n Note 3:<\/strong> 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.<\/p>\n 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.<\/p>\n 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.<\/em><\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69746","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69746","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69746\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69746"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69746"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
