Technical specifications and scope of the EN 10302 standard<\/h2>\n

The European standard EN 10302 sets requirements for wrought steels and special alloys designed for operation at high temperatures (above 500\u00b0C). These materials possess high creep resistance and heat resistance, making them indispensable for the production of critical industrial equipment components operating under prolonged mechanical stress.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

    EV Group China supplies metal products that comply with these technical specifications. If necessary, the use of heat-resistant steel grades according to EN 10095 is permitted, provided it is stipulated by project requirements and agreed upon with the customer.<\/p>\n

    The EN 10302 standard regulates the supply of various types of metal products: hot-rolled and cold-rolled sheets, strips, bars, wire, and shaped profiles. General requirements for quality and acceptance of products comply with the provisions of EN 10021.<\/p>\n

    It should be noted that this standard does not apply to products for the aerospace industry and pressure equipment, nor does it cover parts that have undergone additional processing capable of altering their original physical and mechanical properties.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70099","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70099","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\/70099\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70099"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70099"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
