Notre billette ronde de 250 mm de diam\u00e8tre est fabriqu\u00e9e en acier au carbone 45# de haute qualit\u00e9 (\u00e9quivalent \u00e0 l'ASTM 1045), offrant une solidit\u00e9 sup\u00e9rieure, une excellente r\u00e9sistance \u00e0 l'usure et des performances fiables pour les applications lourdes. Cette billette de grand diam\u00e8tre est con\u00e7ue pour r\u00e9pondre aux exigences des machines industrielles, des syst\u00e8mes automobiles et de la fabrication d'\u00e9quipements pour lesquels des propri\u00e9t\u00e9s m\u00e9caniques et une durabilit\u00e9 accrues sont essentielles. La nuance 45# offre une duret\u00e9 et une r\u00e9sistance \u00e0 la traction optimales, ce qui la rend id\u00e9ale pour les composants critiques qui subissent des contraintes et une usure importantes.<\/p>","protected":false},"featured_media":2433,"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":"","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-2454","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\/2454","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=2454"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media\/2433"}],"wp:attachment":[{"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/media?parent=2454"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_brand?post=2454"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_cat?post=2454"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/fr\/wp-json\/wp\/v2\/product_tag?post=2454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
