Forgings have a far-reaching significance in our daily life, and there are also many categories and types. Some of them are called die forgings. The die forgings need to be used in the forging process, so will the forgings affect the life of the die?The following is your detailed introduction:

According to the alloying degree of die steel, the conventional hot die steels in China are 5CrNiMo and 5CrMnM.Such ordinary grade of mold steel and 4Cr5W2VSi, 4Cr5MoVlSi, 4Cr5MoVSi, 3Cr2W8V and the self-made 3Cr3Mo3VNb, 3Cr2MoVNi (B2), 3Cr2MoWVN (B3), 35Cr3Mo3W2V (HM1), 25Cr3Mo3VNb (HM3), 4Cr3Mo3W4VTiNb (GR), 5Cr4W5Mo2V (RM2),50Cr4Mo3SiMnVAl (012A1), 6Cr4Mo3Si2WV(CG20), SRM-1, etc.

Die steels with higher alloying degree;Common conventional cold die steels include CrWMn, Crl2, Crl2MoV, etc., 7CrSiMnMoV(CH), 65Cr4W3Mo2VNb(65Nb), SLM-LL, 6W8Cr4VTi(LMl), and cemented carbide and steel-bonded cemented carbide developed by China.

The former price is cheap, but the comprehensive use is poor, the life is short;And latter performance is better, life is longer, but the price is more expensive also.Its life and economy should be analyzed according to the forging parts, die forging technology and forging equipment conditions.Generally speaking, choose a slightly higher price but cost-effective advanced mold materials more economic.
