It offers relatively high yield strength while maintaining a practical balance of impact toughness, weldability, and manufacturing cost. Common applications include machine bases, mounting plates, load-bearing brackets, connecting components, and large structural frames, many of which require precise S355 steel machining after cutting or welding. However, S355 is not a single material with completely fixed properties. Different suffixes indicate specific impact requirements or delivery conditions, while material thickness also affects the guaranteed minimum yield strength. For this reason, material selection, structural design, and CNC process planning should consider the exact S355 grade, thickness, and [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":11696,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-11694","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/11694","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/comments?post=11694"}],"version-history":[{"count":3,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/11694\/revisions"}],"predecessor-version":[{"id":11701,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/11694\/revisions\/11701"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/media\/11696"}],"wp:attachment":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/media?parent=11694"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/categories?post=11694"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/tags?post=11694"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
