Products from EV Group China, supplied in accordance with this standard, include UNS grades N06600, N06601, N06603, N06690, N06693, N06025, N06045, N06696, N06617, and N06674.\n<\/p>\n<p>\n    Key quality requirements for products from EV Group China include strict adherence to chemical composition according to UNS specifications, as well as ensuring microstructural homogeneity across the entire cross-section of the product. The surface of the finished rolled stock must be free from technological defects, laps, cracks, and scale, which is critical for further machining and operation in aggressive environments.\n<\/p>\n<p>\n    Mechanical properties (yield strength, tensile strength, elongation, and hardness indicators) are determined by conducting static tensile tests and hardness measurements in accordance with regulated inspection procedures.\n<\/p>\n<p>\n    In EV Group China&#8217;s technical documentation, inch-pound units are preferred, which corresponds to the original text of the ASTM specification. Values in SI units provided for reference are for informational purposes only.\n<\/p>\n<p>\n    Operational safety of products compliant with the ASTM B166 standard is ensured based on current Material Safety Data Sheets (MSDS) provided by EV Group China for each specific alloy grade. Section 12 of the specification regulates exclusively test methods and is not a safety manual for the design or installation of equipment.\n<\/p>\n<p>\n    <b>Technical Notes:<\/b>\n<\/p>\n<ul>\n<li><sup>a<\/sup> Products intended for the manufacture of boilers and pressure vessels must comply with the ASME SB-166 specification (Section II of the ASME Code).<\/li>\n<li><sup>b<\/sup> Alloy marking is carried out according to the Unified Numbering System (UNS) in compliance with the requirements of ASTM E527 and SAE J1086.<\/li>\n<\/ul>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69535","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69535","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\/69535\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69535"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69535"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
