W18Cr4V

Description

W18Cr4V为钨系高速钢,具有高的硬℃、红硬性及高温硬℃。其热处理范围较宽淬火不易过热,热处理过程不易氧化脱碳,磨削加工性能较好。该钢在500℃及600℃时硬℃分别保持在HRC63~64及HRC62~63,对于大量的、一般的被加工材料具有良好的切削性能。

W18Cr4V is a tungsten high speed steel with high hardness, red hardness and high temperature hardness. Its heat treatment range is wide, quenching is not easy to overheat, oxidation decarburization is not easy in the heat treatment process, and grinding performance is good. The hardness of the steel is maintained at HRC63 ~ 64 and HRC62 ~ 63 at 500 ℃ and 600 ℃, respectively. It has good cutting properties for a large number of general processed materials.

W18Cr4V Steel is a widely used tungsten general-purpose high-speed steel with high hardness, red hardness and high temperature hardness, which is easy to grind. It is suitable for cutting tools whose working temperature is below 600 ℃ and can still maintain cutting performance, such as turning, planing, milling, reaming, broach, drill bit, various gear tools, taps and dies. It is suitable for processing soft or medium hardness (below 300 ~ 320hb). And making high temperature wear-resistant mechanical parts
