Increasing durability of hammer dies’ steel by carbonization in paste carburizing material
https://doi.org/10.22349/1994-6716-2018-95-3-13-21
Abstract
The paper considers carbonization features of die steels such as 5Kh2MNF (5Х2МНФ) and 5KhNSV (5ХНСВ) in azotic-carbonic paste in order to use it as a material for die makers. The results of examination of cemented carbide tools made of mentioned steel grades are given and the microstructure of carburized layers is shown. The changes of carbon concentration according to the depth of diffusion layers of examined samples are analyzed.
