It is also used for certain types of shear blades.<\/p>\n<div class=\"ads2-gal\"><figure class=\"ads2-fig\"><img decoding=\"async\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/Cr5Mo1V.avif\" alt=\"Cr5Mo1V\"><figcaption>Cr5Mo1V steel<\/figcaption><\/figure><figure class=\"ads2-fig\"><img decoding=\"async\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/03\/A2-MATERIAL.webp\" alt=\"A2 tool steel\"><figcaption>A2 tool steel<\/figcaption><\/figure><figure class=\"ads2-fig\"><img decoding=\"async\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/A2-STEEL.webp\" alt=\"A2 STEEL\"><figcaption>A2 tool steel plates<\/figcaption><\/figure><\/div>\n<div class=\"ads2-cta popmake-16052\"><a class=\"ads2-btn\" href=\"#\">Open RFQ Form<\/a><\/div>\n<\/section>\n<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Cr5Mo1V Cold Work Tool Steel Aobo Steel- Trusted Global Tool Steel Supplier Send Inquiry Now Cr5Mo1V is a medium alloy air-hardening cold work tool steel, also classified as a high carbon medium chromium tool steel.
