W6Mo5Cr4V2 high-speed tool steel blade
Lack of this entry card figure, add more complete, relevant content to make entry also can rapid upgrade, hurriedly to edit!
W6Mo5Cr4V2 steel W6 or 6542 for short, is a representative of the general type high speed steel tungsten molybdenum steel grade. It is contains many of the high alloy steel, alloy elements leydig shape steel. With high hardness, high wear resistance, high hardness, high hardenability and enough plasticity and toughness, and have good casting, forging, welding and machining performance, so it occupies in the tool steel and the important position.
Chinese high speed tool steel W6Mo5Cr4V2 material name High-speed tool steel bar card number W6Mo5Cr4V2 standards GB/T 9943-1988
