High Speed Steel

High speed steel is a type of steel alloys, typically used during steel for cutting tools. This is also used in propellers bits and drill on electric-saw. High-speed steels provide specialized mechanical and physical characteristics which make them better proponents for production processes with such an optimized series of good strength , wear resistance, hardness and durability.Commonly used during metal cutting like bent drill bits, taps, cutters for grinding, saws, knives etc. High speed and light slashes also generally used during cold work uppercuts and dies and cutting procedures. Globally, the M2 sort is perhaps the most prominent high speed steel simply replacing T1 high speed due to its excellent characteristics and relative efficiency in most methods.

M2

M2 is a tungsten-molybdenum high-speed steel. It is a popular grade for general purpose cutting and non-cutting application. It has a wider heat-treating range than most of the molybdenum high-speed steels, coupled with a resistance to decarburization that is a characteristic property of tungsten types. M2 offers an excellent combination of red-hardness, wear resistance, and toughness. We have made M2 available in a wide variety of shapes and sizes. As with all Alro Specialty Metal products, M2 is subjected to a variety of inspection and rigid quality control tests to ensure quality, uniformity, and reliability.

High-speed steel featuring high resistance to adhesive and abrasive wear in combination with high toughness and compressive strength. Blocks for eroding, cold forming tools such as cutting, fine blanking and impact extrusion punches and dies inserts with a very high wear resistance.

Application:

Broaches, Boring Tools, Chasers, Cold Forming Rolls, Cold Heading Inserts, Drills, End Mills, Form Tools, Hobs, Lathe and Planer Tools, Punches, Milling Cutters, Taps, Reamers, and Saws.

M42

M42 is a molybdenum-cobalt high-speed steel capable of being hardened to 70 Rockwell C. The carbon content is higher than in most high-speed steels, and with this balanced composition, contributes to wear resistance and hot hardness as well as the high hardness capability. M42 exhibits good grindability and relatively good toughness at high hardness levels. M42 is being used for the machining of heat treated materials (high hardness) and high temperature alloys.

 Application:

Broaches, Circular and Dovetail Form Tools, Drills, End Mills, Lathe Tools, Milling Cutters, Punches, Reamers, Slitting Saws, and Twist Drills.
