Hardware tools for high carbon steel or chrome vanadium steel.
Cr4W2MoV, Cr6WV, Cr5MoV and other high carbon chromium tool steel used in the mold, the chromium content of their low eutectic carbides, carbides distribution, heat treatment, small deformation, good hardenability and dimensional stability. Compared with the high carbon high chromium steel and carbide segregation is relatively serious, the performance improved.
Low alloy tool steel is based on carbon tool steel with the proper amount of alloying elements. Compared with the carbon tool steel, the quenching deformation and cracking tendency are reduced, and the hardenability of the steel is improved, and the abrasion resistance is better. The low-alloy steels used for the manufacture of dies include CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD), etc..
The carbon tool steel used in the mould is T8A, T10A and so on. The advantages are good processing performance and low price. But the hardenability and red hardness are poor, the heat treatment deformation is large, and the bearing capacity is low.
With better chrome vanadium steel hardware tools, but the high cost of high carbon steel.The materials for manufacturing hardware and moulds are steel, carbide, steel bonded carbide, zinc based alloy, low melting point alloy, aluminum bronze, high polymer material, and so on. The manufacture of metal mold material mostly by steel products, type of die components materials commonly used are: low carbon tool steel, alloy tool steel, high carbon high chromium or chromium tool steel, carbon steel, high speed steel, steel matrix and hard alloy, steel bonded hard alloy and so on.
