Products from EV Group China, manufactured according to the ASTM B569 standard, are optimized for the high-tech production of heat exchanger tubes used in internal combustion engine cooling systems and industrial closed-loop heat exchange circuits.<\/p>\n<p>The manufacturing process of the workpiece (cast bar, slab, or plate) guarantees a high degree of alloy purity, ensuring stability during hot and cold deformation, as well as subsequent thermal annealing. The result is the formation of a homogeneous metallurgical structure, which is essential for the reliable operation of products under cyclic loads.<\/p>\n<p>EV Group China supplies rolled products in the following tempers:<\/p>\n<ul>\n<li>H01 (1\/4 hard);<\/li>\n<li>H02 (1\/2 hard);<\/li>\n<li>O81 (annealed before tempering, 1\/4 hard);<\/li>\n<li>O82 (annealed before tempering, 1\/2 hard).<\/li>\n<\/ul>\n<p>Each batch of products undergoes multi-stage quality control, including precision geometric measurements, comprehensive mechanical testing, grain size evaluation, and spectral analysis of chemical composition in accordance with ASTM protocols.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69880","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69880","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\/69880\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69880"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69880"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
