It is supplied in a square cross-section. Its core components are high carbon(C) and high chromium(Cr). It has the key characteristics of high hardness(HRC 60-64 after quenching),high wear resistance,and good hardenability(but relatively low toughness). It is mainly used to manufacture cold working dies(such as stamping dies, cold heading dies, shearing dies)that bear cold stamping, shearing ,forming, and other loads, as well as high-wear-resistance mechanical parts under cold working conditions.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"384\" src=\"http:\/\/qilusteelgroup.com\/wp-content\/uploads\/2024\/09\/interior-view-steel-factory-.jpg\" alt=\"d2 tool steel hardness\" class=\"wp-image-8819\" srcset=\"https:\/\/qilusteelgroup.com\/wp-content\/uploads\/2024\/09\/interior-view-steel-factory-.jpg 576w, https:\/\/qilusteelgroup.com\/wp-content\/uploads\/2024\/09\/interior-view-steel-factory--300x200.jpg 300w, https:\/\/qilusteelgroup.com\/wp-content\/uploads\/2024\/09\/interior-view-steel-factory--18x12.jpg 18w, https:\/\/qilusteelgroup.com\/wp-content\/uploads\/2024\/09\/interior-view-steel-factory--500x333.jpg 500w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-are-the-main-applications-of-cr12-square-steel\">What Are the Main Applications of Cr12 Square Steel?<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p>Due to its core characteristics of high hardness, high wear resistance, and good hardenability, Cr12 square steel is primarily used in two fields: cold working die manufacturing and the production of high-wear resistance parts under cold working conditions. The specific scenarios are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cold working die manufacturing(core application):<\/strong> Can be processed into various cold forming\/cutting dies, such as cold stamping dies for automotive parts\/electronic components\/hardware, cold heading dies for bolts\/nuts\/rivets, shearing dies for steel plates\/wires, and powder metallurgy dies for products such as magnetic cores\/gears. Its high wear resistance extends the service life of the dies and ensures forming accuracy.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Production of high-wear-resistant parts: <\/strong>Used to manufacture mechanical parts that withstand friction and wear under cold working conditions, such as cold crushing teeth of crushers, wear-resistant liners of conveying equipment, guide rollers of cold rolling mills, etc., to meet the wear resistance requirements in low-impact environments.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"advantages-of-cr12-square-steel\">Advantages of Cr12 Square Steel<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Advantage<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td><strong>High Wear Resistance<\/strong><\/td><td>Contains abundant chromium carbides; hardness reaches HRC 60-64 after quenching, significantly extending the service life of dies and parts.<\/td><\/tr><tr><td><strong>Good Hardenability<\/strong><\/td><td>Even large-section steel can be hardened through to the core, making it suitable for large molds and preventing soft spots.<\/td><\/tr><tr><td><strong>Excellent Dimensional Stability<\/strong><\/td><td>Minimal deformation after heat treatment and low thermal expansion coefficient ensure precision in mold processing.<\/td><\/tr><tr><td><strong>Ease of Machining<\/strong><\/td><td>Easy to rough machine in the annealed state and can be finished by grinding after quenching, balancing efficiency and accuracy.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/encrypted-tbn0.gstatic.com\/images?q=tbn:ANd9GcR8A-PaYM-F29GL8_TNw5_s1IRbdjLjxnTV-Q&amp;s\" alt=\"\" style=\"width:329px;height:auto\"\/><\/figure>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p>High wear resistance: Contains high chromium carbide, with a hardness of HRC 60-64 after quenching, which can significantly extend the service life of cold-working dies and wear-resistant parts.<\/p>\n\n\n\n<p><strong>Good hardenability:<\/strong> Even after quenching, large-section square steel can be hardened even at the core, which makes it suitable for large cold-working molds and prevents localized soft spots.<\/p>\n\n\n\n<p><strong>Dimensional stability:<\/strong> After heat treatment, deformation is minimal, and the coefficient of linear expansion is low, ensuring product accuracy in precision mold processing.<\/p>\n\n\n\n<p><strong>Easy to process and adapt: <\/strong>It is easy to rough machine in the annealed state, and it can be refined by grinding after quenching, taking into account both efficiency and precision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq\">FAQ<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list\">\n<div id=\"faq-question-1758611014149\" class=\"rank-math-list-item\">\n<h5 class=\"rank-math-question\"><strong>What\u2019s the difference between Cr12 square steel and ordinary steel (such as Q235)?<\/strong><\/h5>\n<div class=\"rank-math-answer\">\n\n<p>The core difference lies in performance positioning&#8211;Q235 is a low-carbon structural steel that focuses on toughness and easy processing, and it is used in construction and general components.Cr12 square steel is a mold steel that focuses on high hardness(HRC 60-64 after quenching) and high wear resistance,and is designed specifically for cold working molds.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1758611030159\" class=\"rank-math-list-item\">\n<h5 class=\"rank-math-question\"><strong>What\u2019s the core advantage of Cr12 square steel?<\/strong><\/h5>\n<div class=\"rank-math-answer\">\n\n<p>High wear resistance,because it contains a large amount of chromium carbide hard phase,can withstand the high-frequency friction of cold stamping and shearing,greatly extending the life of the mold. Secondly, it has good hardenability,and the core of large-section square steel can also be hardened,making it suitable for large molds.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1758611038691\" class=\"rank-math-list-item\">\n<h5 class=\"rank-math-question\"><strong>What is the toughness of Cr12 square steel?<\/strong><\/h5>\n<div class=\"rank-math-answer\">\n\n<p>The toughness is relatively low, and it is only suitable for cold,low-impact scenarios(such as cold stamping and cold heading). If it is subjected to a large impact (such as hot forging and heavy hammer stamping), it is easy to crack and needs to be replaced with steel with better toughness(such as Cr12MoV).<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Buy Cr12 Square Steel\u2014durable, wear-resistant, and ideal for molds, tools, and industrial applications requiring strength and precision.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_gspb_post_css":"","footnotes":""},"categories":[42,37],"tags":[],"class_list":["post-12809","post","type-post","status-publish","format-standard","hentry","category-blog","category-tool-steel"],"blocksy_meta":[],"_links":{"self":[{"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/posts\/12809","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/comments?post=12809"}],"version-history":[{"count":2,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/posts\/12809\/revisions"}],"predecessor-version":[{"id":12811,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/posts\/12809\/revisions\/12811"}],"wp:attachment":[{"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/media?parent=12809"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/categories?post=12809"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/qilusteelgroup.com\/pt\/wp-json\/wp\/v2\/tags?post=12809"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
