The main difference is their minimum yield strength: <strong class=\"font-semibold text-stone-950\">S235 has a minimum yield strength of 235 MPa<\/strong>, while <strong class=\"font-semibold text-stone-950\">S275 has a minimum yield strength of 275 MPa<\/strong>. This means S275 can withstand a greater load before permanently deforming.<\/p>\n<p class=\"an-md-p my-2.5 max-w-[48rem] text-[15px] leading-[1.62] text-stone-800 first:mt-0 last:mb-0\">Both grades offer good weldability, machinability and value for general fabrication. S235 is often used for hollow sections and general structural applications, while S275 is commonly specified for flat bar, round bar, square bar, angles and channels where additional strength is beneficial. Always check the required material grade against the project&#8217;s structural specification.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>S235 and S275 are both commonly used structural mild steel [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"footnotes":""},"faq_category":[186],"class_list":["post-22791","avada_faq","type-avada_faq","status-publish","format-standard","hentry","faq_category-mild-steel"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.1 (Yoast SEO v28.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>What is the difference between S235 and S275 mild steel?
