The ASTM B649 specification (identical to ASME SB 649) establishes strict requirements for the quality and chemical composition of finished bars and wire manufactured from high-alloy corrosion-resistant alloys. The list of regulated materials includes nickel-iron-chromium-molybdenum-copper-nitrogen compositions (UNS N08925, UNS N08031, UNS N08354, UNS N08926), chromium-nickel-iron-nitrogen alloys (UNS R20033), as well as wire made from nickel-chromium-iron-molybdenum-nitrogen alloy (UNS N08936).<\/p>\n
EV Group China ensures the supply of metal products that fully comply with these engineering standards. It is important to note that the classification of certain alloys, such as UNS N08904, has been revised by the ASTM International committee. Due to their high iron content, these materials are now legally classified as stainless steels and are governed by the relevant ASTM A479 \/ A479M and A484 \/ A484M standards.<\/p>\n
Technical documentation and quality control of the products are carried out under the auspices of the ASTM A01 Committee. When designing and selecting materials, it should be noted that the ASTM B649 standard is based on the inch-pound system of units. Metric equivalents, presented in parentheses, are for reference purposes to facilitate calculations in the global market.<\/p>\n
The operational safety of the products supplied by EV Group China is ensured by strict adherence to manufacturer specifications. All matters related to occupational health and safety when working with these alloys are regulated by current Material Safety Data Sheets (MSDS) provided along with the shipping documentation for the metal batch.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-70175","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70175","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\/70175\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70175"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70175"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
