PostSubject: T1 speed tool steel   Wed Feb 16, 2011 11:55 pm



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:

Carbon
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.
Vanadium
Forms special carbides of supreme hardness, increases high temperature wear resistance, retention of hardness and high temperature strength.
Chromium
Promotes depth hardening, produces readily soluble carbides.
Cobalt
Improves red hardness and retention of hardness.
Aluminum
Improves retention of hardness and red hardness



Advantages

_ Can be used for red-hot (1400F) applications

_ Good shock resistance

_ Good abrasion resistance

Typical Uses

_ wide variety of cutting applications

Don,

I hope our Undercutters are not similiar in design.... Would not be good !

62 Rock is what I have been told for Ti

you probable want to aim between 40-50, anything higher is meant for cutting operations and wouldn't handle the constant shock of impacts.

HSS (and carbide especially) is actually pretty brittle when it gets that hard--ever dropped an endmill by accident, and ended up with a useless chunk of metal (or two)? (happened to me with a nice 1/2 inch 4 flute carbide one just yesterday) Or tried to mill something several inches longer than your vise? The shock/impact just ruins it.

Don't get me wrong--I hope it works for you, but I have my doubts--I fear it might be a case of one good hit and it's game over.

From glancing at some overviews of the materials, I would shy away from using T1 or any other HSS as a large weapon component - they're far more brittle and prone to fracture than the more common flavors of tool steel on the market (like A2 & S7). However, if you used it exclusively for teeth I don't see any problem with that choice of steel.

I left my heat treating up to my professional friend but what he did was heat treat our metal to what he deemed optimal then did a quick reheat to give it a slight softness back to it. He stated that this was standard for the super heavy duty machining and stamping machines he does work for. He does it for a living and did it for free. Can you really argue against that?

Optimally, I wouldn't use HSS for a major structural element of a weapon - if cost is an issue (ie: if you HAVE to use HSS), there may be an appropriate heat treating procedure to get you the necessary toughness and strength for the weapon to last. Heat treating steel to a high temperature for a quench and then tempering it is fairly standard across an extremely wide variety of steel grades; it's a common method for ensuring a material has a specific set of properties. I am not familiar enough with T1 to say whether it is possible to obtain the desired characteristics for this specific application.
