Due to its ability to achieve a high-polish finish and maintain good durability, this grade is widely used in the manufacture of cutlery, knives, scissors, and surgical instruments.<\/p>\n<p data-start=\"310\" data-end=\"331\"><strong data-start=\"310\" data-end=\"329\">Key Characteristics<\/strong><\/p>\n<ul>\n<li data-start=\"333\" data-end=\"426\"><strong data-start=\"333\" data-end=\"359\">Corrosion Resistance:<\/strong> 420J2 offers excellent resistance to moisture, water, and mildly corrosive atmospheric environments, making it suitable for everyday applications where exposure to humidity is common.<\/li>\n<li data-start=\"428\" data-end=\"543\"><strong data-start=\"428\" data-end=\"449\">Hardness and Strength:<\/strong> This grade can be heat-treated to achieve high strength and hardness. Owing to its higher carbon content, 420J2 generally provides better hardness and wear resistance than 420J1.<\/li>\n<li data-start=\"545\" data-end=\"613\"><strong data-start=\"545\" data-end=\"563\">Impact Toughness:<\/strong> 420J2 exhibits good impact resistance and overall mechanical durability, allowing it to withstand routine mechanical stresses during use.<\/li>\n<li data-start=\"615\" data-end=\"761\"><strong data-start=\"615\" data-end=\"641\">Edge Retention:<\/strong> Edge retention is generally considered moderate. Therefore, 420J2 is commonly used for affordable, everyday cutting tools rather than premium high-end knives requiring long-lasting sharpness.<\/li>\n<\/ul>\n<p data-start=\"810\" data-end=\"834\"><strong data-start=\"810\" data-end=\"832\">Common Applications:<\/strong><\/p>\n<ul>\n<li data-start=\"836\" data-end=\"879\"><strong data-start=\"836\" data-end=\"848\">Cutlery and Personal Care Tools:<\/strong> Kitchen knives, scissors, nail clippers, nail files, tweezers<\/li>\n<li data-start=\"881\" data-end=\"951\"><strong data-start=\"881\" data-end=\"904\">Medical and Industrial Applications:<\/strong> Surgical instruments, medical tools, general industrial tools<\/li>\n<li data-start=\"953\" data-end=\"1014\"><strong data-start=\"953\" data-end=\"970\">Mechanical Components:<\/strong> Gears, shafts, various mechanical parts and components<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<ul>\n<li>Grade: 410J2 (30Cr13, 1.4028)<\/li>\n<li>Type: Wire, coil, sheet, round bar<\/li>\n<li>Thickness, size, surface: as required<\/li>\n<li>Packaging: as requested<\/li>\n<li>Origin: Germany, China, India<\/li>\n<li>MOQ and delivery time: please contact for more details<\/li>\n<\/ul>","protected":false},"featured_media":32196,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[1449],"product_tag":[],"class_list":["post-32095","product","type-product","status-publish","has-post-thumbnail","product_cat-thep-khong-gi","first","instock","shipping-taxable","product-type-simple"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/product\/32095","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/comments?post=32095"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/media\/32196"}],"wp:attachment":[{"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/media?parent=32095"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/product_brand?post=32095"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/product_cat?post=32095"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/tranmi.com\/en\/wp-json\/wp\/v2\/product_tag?post=32095"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
