Notre billette ronde de 300 mm de diam\u00e8tre est fabriqu\u00e9e \u00e0 partir d'un acier alli\u00e9 40Cr de haute qualit\u00e9 (\u00e9quivalent \u00e0 l'ASTM 5140). Elle offre une solidit\u00e9, une t\u00e9nacit\u00e9 et une r\u00e9sistance \u00e0 l'usure exceptionnelles pour les applications industrielles les plus exigeantes. Ce billette de grand diam\u00e8tre combine l'am\u00e9lioration de l'alliage de chrome avec des processus de fabrication pr\u00e9cis pour offrir des propri\u00e9t\u00e9s m\u00e9caniques sup\u00e9rieures. La nuance 40Cr offre une excellente trempabilit\u00e9 et r\u00e9sistance \u00e0 la fatigue, ce qui la rend id\u00e9ale pour les composants critiques des industries automobile, a\u00e9rospatiale et de l'\u00e9quipement lourd o\u00f9 la fiabilit\u00e9 et la performance sont primordiales.<\/p>","protected":false},"featured_media":2438,"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-2455","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\/2455","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=2455"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media\/2438"}],"wp:attachment":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media?parent=2455"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_brand?post=2455"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_cat?post=2455"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_tag?post=2455"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
