This composition, widely known in the industry as 85-5-5-5, complies with the international standard UNS C83600. Products supplied by EV Group China are focused on critical components for valves, flange connections, and specialized fittings that require high corrosion resistance and stable properties in operating environments.<\/p>\n<p>Castings produced according to this standard are intended for further mechanical processing or direct installation within engineering systems.<\/p>\n<h3>Regulatory framework and standardization<\/h3>\n<p>The requirements of the ASTM B62 standard are closely integrated with the provisions of ASTM B824. In case of conflicts between standards, the ASTM B62 document takes precedence. The terminology used for material classification and defect definition is based on the ASTM B846 standard.<\/p>\n<h3>Ordering parameters at EV Group China<\/h3>\n<p>To ensure the correct execution of an order for UNS C83600 alloy castings, the technical documentation must contain the following data:<\/p>\n<ul>\n<li>Exact volume of the casting batch in pieces or weight units.<\/li>\n<li>Material identification: UNS C83600.<\/li>\n<li>Specification article number indicating the current revision year.<\/li>\n<li>Drawing specification and required stage of readiness (as-cast or after finish machining).<\/li>\n<li>Requirement for hydraulic leak testing (optional).<\/li>\n<li>Requirements for providing quality certificates and laboratory test reports.<\/li>\n<li>Requirement for acceptance inspections with the customer&#8217;s representative.<\/li>\n<li>Specific requirements for marking finished products.<\/li>\n<\/ul>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69761","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69761","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\/69761\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69761"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69761"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
