强韧化处理是热处理工艺的一项新技术。同样的材料在经过强韧化处理以后,可以获得较好的机械性能。用它制成的产品,具有性能稳定、可靠,延长使用寿命等优点。因此,它是一项能发挥材料潜在能力的好的工艺。通常用的制造锻模的材料有5CrMnMo、3Cr2W8V,以及某些新型的无镍,铬材料等。由于我局每年都有成批量的车轮报废,因此,我厂常用含碳量0.5～0.7%的轮箍钢代替上述材 Toughening is a new technology for heat treatment. The same material after toughening treatment, you can get better mechanical properties. Made with it products, with stable performance, reliability, extend the service life and so on. Therefore, it is a good process that can exert the potential of materials. Commonly used forging die materials are 5CrMnMo, 3Cr2W8V, as well as some new nickel-free, chromium materials. Since our bureau scrapped the wheels of the car in batches every year, the steel commonly used by our factory instead of the above materials is the wheel steel with the carbon content of 0.5 ~ 0.7%
