High-speed steel/
Introduction
/ / / /
/ / / /
High-speed steel (
is a high-cobalt toughness high-speed steel, mainly used for high-toughness precision wear-resistant hardware Cold stamping dies can also be used for cooling in cutting tools and knives. The steel has high hardness, up to
good thermal hardness, high hardness at high temperatures, and easy grinding. Cutting tools made of this steel can cut iron-based high-temperature alloys, Cast high-temperature alloys, titanium alloys and ultra-high-strength steels, etc., but the toughness is slightly lower, and the lower limit should be used for quenching temperature. Due to its good grindability, it can be used to manufacture various high-precision complex tools.
