DIN1.3343 high speed tool steel,high speed steels for metal-cutting
tools, Dia: 2-400mm
Standard high-speed steel grade. High toughness and good cutting
power owing to its well-balanced alloy composition, making it
suitable for a wide variety of applications. For all metal-cutting
tools for roughing or finishing, such as twist drills, all kinds of
milling cutters, screw taps, screw dies, broaches, reamers,
countersinks, chasers, segments for circular saws, shaping tools
and woodworking tools. Also highly suitable for cold-forming tools,
such as cold extrusion rams and dies, as well as for cutting and
precision cutting tools, plastics moulds with elevated wear
resistance and screws.

High Speed Steel got hardness method: 1. Salt bath hardening or
vacuum hardening 2. the temperature 1180-1200°C, if need high
hardness add 10°C 3. in the temperature 560°C, tempering more than
3 times. The most important: control hardening temperature and
