Sim. A norma DIN\/EN 1.2344 \u00e9 o equivalente europeu do a\u00e7o H13.<\/p>\n\n\n\n

H13 is the AISI \/ SAE \/ ASTM designation. 1.2344 is the DIN \/ EN material number. In European specifications, 1.2344 is also known as X40CrMoV5-1. The P\u00e1gina do a\u00e7o ferramenta 1.2344<\/a> breaks that number down and lists the other tool steel grades that carry a 1.23 number.<\/p>\n\n\n\n

Em compras, os a\u00e7os H13 e 1.2344 s\u00e3o geralmente tratados como equivalentes. O comprador deve, no entanto, confirmar se o pedido exige alguma norma, como ASTM, DIN\/EN, JIS, GB ou outra norma previamente acordada. Isso \u00e9 importante quando o projeto possui requisitos rigorosos em rela\u00e7\u00e3o \u00e0 composi\u00e7\u00e3o qu\u00edmica, testes ultrass\u00f4nicos, toler\u00e2ncia dimensional ou certifica\u00e7\u00e3o.<\/p>\n\n\n\n

Caso um comprador envie uma solicita\u00e7\u00e3o para SKD61, o fornecedor dever\u00e1 confirmar se o cliente aceita material equivalente a H13\/1.2344\/SKD61. O pedido tamb\u00e9m dever\u00e1 especificar as dimens\u00f5es, condi\u00e7\u00f5es, toler\u00e2ncias, acabamento superficial, n\u00edvel de inspe\u00e7\u00e3o e requisitos de certifica\u00e7\u00e3o.<\/p>\n\n\n\n

A nomenclatura chinesa reflete a composi\u00e7\u00e3o da liga. O "4" indica aproximadamente 0,4% de carbono. "Cr5" indica aproximadamente 5% de cromo. "Mo", "Si" e "V1" indicam adi\u00e7\u00f5es de molibd\u00eanio, sil\u00edcio e van\u00e1dio, respectivamente.<\/p>\n\n\n\n

Para fins de comunica\u00e7\u00e3o com exportadores, os fornecedores chineses costumam escrever esse material como H13 \/ 1.2344 \/ SKD61 \/ 4Cr5MoSiV1. Isso esclarece a equival\u00eancia para compradores internacionais e reduz mal-entendidos durante consultas, or\u00e7amentos e an\u00e1lises de documentos.<\/p>\n\n\n\n

O \u201cT\u201d em UNS T20813 identifica o material como um a\u00e7o ferramenta. Em documentos t\u00e9cnicos, a norma UNS T20813 ajuda a evitar confus\u00e3o quando v\u00e1rios sistemas de nomenclatura de classes s\u00e3o usados em conjunto.<\/p>\n\n\n\n

Se um desenho especificar UNS T20813, um fornecedor normalmente pode cotar a\u00e7o ferramenta H13, desde que o material atenda aos requisitos de padr\u00e3o, condi\u00e7\u00e3o, inspe\u00e7\u00e3o e documenta\u00e7\u00e3o exigidos.<\/p>\n\n\n\n

Por que essas notas s\u00e3o consideradas equivalentes a H13?<\/h2>\n\n\n\n

Os a\u00e7os H13, 1.2344, SKD61, 4Cr5MoSiV1, X40CrMoV5-1 e UNS T20813 s\u00e3o considerados equivalentes por serem baseados no mesmo projeto de a\u00e7o para trabalho a quente \u00e0 base de cromo-molibd\u00eanio-van\u00e1dio.<\/p>\n\n\n\n

Uma composi\u00e7\u00e3o t\u00edpica de H13 \u00e9:<\/p>\n\n\n\n

Essa composi\u00e7\u00e3o de ligas confere aos a\u00e7os H13 boa resist\u00eancia a quente, tenacidade, temperabilidade e resist\u00eancia \u00e0 fadiga t\u00e9rmica. O cromo contribui para a temperabilidade. O molibd\u00eanio melhora a resist\u00eancia ao amolecimento em altas temperaturas. O van\u00e1dio contribui para a resist\u00eancia ao desgaste e \u00e0 t\u00eampera.<\/p>\n\n\n\n

O desempenho final ainda depende da qualidade da fabrica\u00e7\u00e3o do a\u00e7o, da qualidade da forja, da dimens\u00e3o da se\u00e7\u00e3o, do tratamento t\u00e9rmico e dos requisitos de inspe\u00e7\u00e3o. \u00c9 por isso que as classes equivalentes devem ser confirmadas tanto pelo nome da classe quanto pela especifica\u00e7\u00e3o do pedido.<\/p>\n\n\n\n
