High-speed steel W18Cr4V Dalian Jingtai has a large inventory of spot W18 round bars

Introduction
It is a tungsten series high-speed tool steel with high hardness, red hardness and high temperature strength. The hardness is at
℃
and
℃
It can still be maintained at
and
respectively. In addition, it also has good high-temperature strength and wear resistance. Its heat treatment temperature range is wide, quenching is not easy to overheat, it is easy to grind, and the heat processing and heat treatment processes are not easy. Oxidative decarburization. It has good cutting performance for general processed materials.
The carbide unevenness and high-temperature plasticity of this steel are worse than those of molybdenum-based high-speed tool steel.
The as-cast structure includes skeletal, carbide flakes and martensite or troostite alternately arranged ledesite, and black structure
(
Segregation
)
and white structure
(
martensite and retained austenite
)
. The as-cast structure and chemical composition of high-speed steel are particularly uneven and cannot be changed by heat treatment. Therefore, pressure processing must be performed to break the coarse eutectic carbides and distribute them evenly, and then use them to make various cutting tools and cutting tools. mold.
