Notre billette ronde de 350 mm de diam\u00e8tre est fabriqu\u00e9e en acier alli\u00e9 40Cr de premi\u00e8re qualit\u00e9 (\u00e9quivalent \u00e0 AISI 5140), offrant des propri\u00e9t\u00e9s m\u00e9caniques et une fiabilit\u00e9 exceptionnelles pour les applications lourdes les plus exigeantes. Ce billette de grand diam\u00e8tre combine l'am\u00e9lioration du chrome avec des processus de fabrication pr\u00e9cis pour offrir une solidit\u00e9, une t\u00e9nacit\u00e9 et une r\u00e9sistance \u00e0 l'usure sup\u00e9rieures. La nuance 40Cr offre une excellente trempabilit\u00e9 et d'excellentes performances en fatigue, ce qui la rend id\u00e9ale pour les composants critiques des \u00e9quipements miniers, des machines lourdes, de la production d'\u00e9nergie et des grands syst\u00e8mes automobiles, o\u00f9 la d\u00e9faillance n'est pas une option.<\/p>","protected":false},"featured_media":2443,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[24],"product_tag":[],"class_list":["post-2456","product","type-product","status-publish","has-post-thumbnail","product_cat-round-billets","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product\/2456","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/comments?post=2456"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media\/2443"}],"wp:attachment":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media?parent=2456"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_brand?post=2456"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_cat?post=2456"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_tag?post=2456"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
