Quais s\u00e3o as classes equivalentes do a\u00e7o ferramenta D3?<\/h1>\n\n\n\n

A\u00e7o ferramenta D3<\/a> \u00e9 geralmente compat\u00edvel com DIN 1.2080, EN X210Cr12, JIS SKD1 e GB Cr12<\/a> Em normas internacionais de a\u00e7o, essas classes s\u00e3o usadas como refer\u00eancias equivalentes por compartilharem uma composi\u00e7\u00e3o semelhante com alto teor de carbono e cromo.<\/p>\n\n\n\n

Para a maioria das aplica\u00e7\u00f5es de ferramentas de trabalho a frio, essas classes s\u00e3o consideradas equivalentes na pr\u00e1tica. Elas s\u00e3o usadas principalmente onde resist\u00eancia ao desgaste abrasivo<\/a> \u00e9 mais importante do que a resist\u00eancia ao impacto.<\/p>\n\n\n\n

Compara\u00e7\u00e3o da composi\u00e7\u00e3o qu\u00edmica<\/h2>\n\n\n\n

O principal motivo pelo qual essas classes de a\u00e7o s\u00e3o consideradas equivalentes \u00e9 o seu teor semelhante de carbono e cromo. Todas as quatro classes s\u00e3o formuladas com alto teor de carbono e cerca de 12% de cromo.<\/p>\n\n\n\n

Essa composi\u00e7\u00e3o confere alta dureza e forte resist\u00eancia ao desgaste abrasivo a esses a\u00e7os ap\u00f3s tratamento t\u00e9rmico<\/a>. O alto teor de carbono contribui para a dureza, enquanto o cromo forma carbonetos duros que resistem ao desgaste.<\/p>\n\n\n\n

D3, 1.2080, SKD1 e Cr12 s\u00e3o exatamente iguais?<\/h2>\n\n\n\n

N\u00e3o. S\u00e3o notas equivalentes, mas n\u00e3o s\u00e3o 100% iguais.<\/p>\n\n\n\n

A diferen\u00e7a reside na norma. ASTM, DIN, EN, JIS e GB nem sempre utilizam exatamente a mesma gama de componentes qu\u00edmicos. Um lote de Cr12 pode funcionar como equivalente a D3 em muitas ferramentas, mas n\u00e3o deve ser certificado como ASTM D3 a menos que sua composi\u00e7\u00e3o atenda aos limites da norma ASTM D3.<\/p>\n\n\n\n

Para uso normal em ferramentas, os usu\u00e1rios podem selecionar essas classes como alternativas. Para projetos mais rigorosos, a norma exigida deve ser claramente especificada no pedido de compra. A composi\u00e7\u00e3o qu\u00edmica, a dureza ap\u00f3s recozimento, as condi\u00e7\u00f5es de entrega e o certificado de teste de f\u00e1brica tamb\u00e9m devem ser verificados antes do envio.<\/p>\n\n\n\n

Em termos simples, D3, 1.2080, SKD1 e Cr12 s\u00e3o equivalentes pr\u00e1ticos para ferramentas de trabalho a frio de alto desgaste, mas a aceita\u00e7\u00e3o final deve sempre seguir a norma especificada.<\/p>","protected":false},"excerpt":{"rendered":"

What Are the Equivalent Grades of D3 Tool Steel? D3 tool steel is commonly matched with DIN 1.2080, EN X210Cr12, JIS SKD1, and GB Cr12 in international steel standards. These grades are used as equivalent references because they share a similar high-carbon and high-chromium composition.
