        60SiCr7 Spring Steel<\/p>\n

        Spring steel DIN 17221 60SiCr7 is a kind of pre-hardened material well suited for fabrication requiring shaping by blanking, bending, drawing, extrusion and swaging. Spring steel DIN 17221 60SiCr7 allows for closer dimensional tolerances and improved finish and available in several grades. Grade selection is important when considering higher levels of wear resistance.<\/p>\n

        DIN 17221 60SiCr7 spring steels are mainly used for the manufacture of railway rolling stock, cars and tractors on the leaf spring and coil spring, the safety valve spring, shock absorber on a variety of heavy machinery, instrument springs, friction plate.<\/p>","protected":false},"featured_media":3862,"comment_status":"open","ping_status":"closed","template":"","meta":{"_gspb_post_css":""},"product_brand":[],"product_cat":[17,19],"product_tag":[],"class_list":{"0":"post-3861","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-all-products","7":"product_cat-spring-steel","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/product\/3861","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/comments?post=3861"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/media\/3862"}],"wp:attachment":[{"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/media?parent=3861"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/product_brand?post=3861"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/product_cat?post=3861"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/qilusteelgroup.com\/es\/wp-json\/wp\/v2\/product_tag?post=3861"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
