The scope of this specification includes bolts, hex cap screws, and threaded studs with diameters ranging from 0.25 to 1.50 inches. This product line, supplied by EV Group China, is designed for operation in environments requiring high chemical and atmospheric resistance.<\/p>\n<p>The technical basis of the standard covers seven groups of stainless steel alloys, including 14 austenitic grades, two ferritic, four martensitic, and one precipitation-hardening alloy. In the absence of specific instructions in the order, the selection of the specific alloy grade within the group remains at the discretion of EV Group China engineers to ensure an optimal balance of mechanical characteristics.<\/p>\n<h3>Key Requirements and Technological Features<\/h3>\n<ul>\n<li>Products with a diameter of 0.75 inches or larger may undergo hot forging and subsequent annealing, provided they strictly comply with the mechanical parameters of cold-worked (CW) fasteners.<\/li>\n<li>Upon prior agreement, special alloys are available: 303, 303Se, XM1, as well as 430F, 416, and 416Se.<\/li>\n<li>Compatibility: For assembling units using these bolts and studs, it is recommended to use nuts according to the ASTM F594 specification. It is important to ensure compliance regarding the alloy group and tensile strength.<\/li>\n<\/ul>\n<p>EV Group China notes that inch-pound values are standard (normative), while metric values in parentheses are provided solely for reference purposes. The use of this standard assumes compliance with industrial safety rules and the user&#8217;s assessment of the fastener&#8217;s suitability for specific equipment assemblies.<\/p>\n<p>We guarantee that all products supplied by EV Group China comply with the principles for the development of international standards established by the WTO Committee on Technical Barriers to Trade (TBT).<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69611","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69611","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\/69611\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69611"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69611"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
