Im making a undercutter weapon made out of T1 to harden it should I go 62-67 HRC or should I go lower
Theres some info about it below thanks
High-Speed Tool Steels
(T for tungsten based and M for molybdenum based) High-speed alloys include all molybdenum (M1 to M52) and tungsten (T1 to T15) class alloys. High-speed tools steels can be hardened to 62-67 HRC and can maintain this hardness in service temperatures as high as 540 °C (1004°F), making them very useful in high-speed machinery. Typical applications are end mills, drills, lathe tools, planar tools, punches, reamers, routers, taps, saws, broaches, chasers, and hobs.
For modern industrial production, in particular mass production, machining is one of the most important shaping and forming processes. Almost all tools employed for this purpose are made from high speed steels.In recent times, the use of high speed steels has gained increasing importance for chipless shaping, e.g. for extrusion, blanking and punching tools.
With regard to chemical composition, a clear distinction is made between 'Tungsten', 'Molybdenum' and 'Tungsten-Molybdenum' alloyed high speed steel grades, which depending on the dominant stresses they will be exposed to, contain different amounts of Carbon, Vanadium and Cobalt.
The characteristic properties of all high speed steel grades include:
- High working hardness
- High wear resistance
- Excellent toughness
- High retention of hardness and Red hardness
The influence of alloying elements on steel properties:
Forms carbides, increases wear resistance, responsible for the basic matrix hardness.
Tungsten & Molybdenum
Improves red hardness, retention of hardness and high temperature strength, forms special carbides of great hardness.
Forms special carbides of supreme hardness, increases high temperature wear resistance, retention of hardness and high temperature strength.
Promotes depth hardening, produces readily soluble carbides.
Improves red hardness and retention of hardness.
Improves retention of hardness and red hardness
_ Can be used for red-hot (1400F) applications
_ Good shock resistance
_ Good abrasion resistance
_ wide variety of cutting applications
