The standard covers five groups of materials, divided into twelve classes according to their yield strength \u2014 from 345 to 827 MPa (50\u2013120 ksi). The products supplied by EV Group China are designed for use in high-load assemblies of power equipment, pressure vessels, and flange connections for shut-off valves.<\/p>\n<p>Materials in this category undergo specific thermal and mechanical processing to ensure dimensional stability and mechanical characteristics during prolonged heating. These products are not intended for general-purpose fastening and require strict adherence to the parameters described in the ASTM A962\/A962M standard.<\/p>\n<h3>Ordering and standardization requirements<\/h3>\n<p>To ensure compliance with design characteristics, the following aspects must be considered when placing an order with EV Group China:<\/p>\n<ul>\n<li>All technological processes must be based on the fundamental requirements of the ASTM A962\/A962M specification.<\/li>\n<li>Supplementary requirements are performed only upon the customer&#8217;s direct request and are stipulated in the contract.<\/li>\n<li>The standard includes both the imperial system of measurement and the metric system (SI). If the designation &#8220;M&#8221; is not specified in the order, the inch-pound units are applied by default.<\/li>\n<\/ul>\n<p>EV Group China engineers emphasize: metric and imperial values in the specification are not direct mathematical equivalents. When designing assemblies, one system of units should be selected to avoid discrepancies in strength calculations.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69961","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69961","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\/69961\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69961"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69961"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
