. It is a kind of cobalt-containing powder high-speed steel. Suitable for making multi-edged tools, such as twist drills, reamers, taps, milling cutters, broaches, hobs and forming tools. Single-edged tools such as cutting tools and forming tools.
In terms of performance, it is suitable for The production requires a certain degree of hardness and multi-edged blades.
.It is also suitable for making single blades with general requirements.
.It is also suitable as a cold work mold that has strict requirements on wear resistance. For example: punching, forming, stamping dies, etc.
.This steel type has excellent wear resistance and toughness, which is better than other high-alloy cold work steels.
.Forming ability, hot forming has good hot forging and hot rolling properties due to its very uniform structure. These properties are useful for other applications such as punch head upsetting, etc. Thermal processing occasions are also important.
.The uniform structure of cold forming enables plastic forming at room temperature. However, due to the composition of its alloy elements, steel has a tendency to work harden under rapid processing, so it has certain limitations on plastic forming.
