Basic Profile:
W6Mo5Cr4V2 high-speed steel tool steel referred to senior engineers or high-speed steel, commonly known as "front steel" or "wind of steel", is a suitable high-speed cutting of high-carbon high alloy tool steel.
Salient features:
It features high hardness, wear resistance and hot hardness (also known as red hardness), when the cutting tool temperature up to 500 ~ 600 degrees Celsius, the hardness is no noticeable decline in low-alloy cutting tools can be of steel than the higher speed cutting, mainly for the manufacture of high cutting speed, heavy load, high temperature variety of cutting tools, such as turning, milling, hob, planer, broaches, drills, taps, etc., can also be used to make required resistance hot and cold deformation wear high mold temperature springs, high temperature bearings.
