Product Description
1.3255 high speed steel is a kind of complex steel with a carbon content of generally 0. 70~1.65%. It contains more alloy elements, with a total amount of 10-25%. According to the different alloy elements, it can be divided into:
1. tungsten high-speed steel (containing 9~18% tungsten);
2. Tungsten molybdenum high-speed steel (containing 5~12% tungsten and 2~6% molybdenum);
3. High molybdenum high-speed steel (containing 0~2% tungsten and 5~10% molybdenum);
4. Vanadium high speed steel can be divided into general vanadium content (1~2% vanadium) and high vanadium content (2% vanadium) according to different vanadium content. High speed steel is 5~5%;
5. Cobalt high-speed steel (containing 5~10% cobalt)
