DCCr12MoV——耐磨铬钢
DCCr12MoV——耐磨铬钢
1国产.较Cr12钢含碳量低,且加入了Mo和V,碳化物不均匀有所改善,MO能减轻碳化物偏析并提高淬透性,V能细化晶粒增加韧性.此钢有高淬透性,截面在400mm以下可以完全淬透,在300~400℃仍可保持良好的硬度和耐磨性,较Cr12有高的韧性,淬火时体积变化小,又有高的耐磨性和良好的综合机械性能.所以可以制造截面大,形状复杂,经受较大冲击的各种模具,例如普通拉伸模,冲孔凹模,冲模,落料模,切边模,滚边模,拉丝模,冷挤压模,冷切剪刀,圆锯,标准工具,量具等。
Compared with Cr12 Steel, the carbon content of domestic steel is lower, and the carbide inhomogeneity is improved by adding Mo and V. Mo can reduce carbide segregation and improve hardenability, V can refine grains and increase toughness. This steel has high hardenability, can be completely quenched when the cross section is less than 400mm, and can still maintain good hardness and wear resistance at 300 ~ 400 ℃. Compared with Cr12, it has higher toughness and smaller volume change during quenching, It also has high wear resistance and good comprehensive mechanical properties. Therefore, it can manufacture various dies with large cross-section, complex shape and large impact, such as ordinary drawing die, punching die, punching die, blanking die, trimming die, rolling die, drawing die, cold extrusion die, cold cutting cutter, circular saw, standard tools, measuring tools, etc.

11. SKD11 -- ductile chromium steel
日本日立株式生产.在技术上改善钢中的铸造组织,细化了晶粒.较Cr12mov的韧性和耐磨性有所提高.延长了模具的使用寿命.
The casting structure of the steel was improved and the grain size was refined. Compared with Cr12MoV, the toughness and wear resistance of the steel were improved and the service life of the die was prolonged
12、D2——高碳高铬冷作钢
12. D2 -- high carbon and high chromium cold working steel
美国产.具有高的淬透性,淬硬性,耐磨性,高温抗氧化性能好,淬火和抛光后抗锈蚀能力好,热处理变形小,宜制造各种要求高精度,长寿命的冷作模具,刀具和量具,例如拉伸模,冷挤压模,冷剪切刀等。
It is made in USA. It has high hardenability, hardenability, wear resistance, high temperature oxidation resistance, good corrosion resistance after quenching and polishing, and small heat treatment deformation. It is suitable to manufacture various cold working dies, tools and measuring tools with high precision and long service life, such as drawing die, cold extrusion die, cold shear knife, etc.
