M2 High Speed Steel
M2 high speed steel stockholders and suppliers, delivering to the whole of the Middle East. Nifty Alloys LLC are suppliers of M2 high speed steel in round bar, sheet and plate which can be bandsaw cut to your specific requirements. As a tungsten molybdenum, general purpose high speed steel, it is widely used in the production of machine tool bits, cold forming tools and cutting tools. M2 high speed steel offers high toughness combined with good cutting powers and will withstand increases in temperature without losing its temper.

M2 Ground Flat Stock
Precision ground flat stock / gauge plate can be produced in M2 tool steel. Subject to size suitability and availability pieces can be produced in approximately 2 to 3 weeks. Standard and non-standard sizes are available.
M2 Tool Bits
M2 high speed steel tool bits are supplied in flats, squares and rounds. Commonly supplied in standards sizes though non standard sizes can be produced within a few weeks, subject to availability of suitable raw material.
Forging
Pre heat slowly and uniformly to 850-900°C. The heat should then be increased more quickly to the forging temperature of 1050-1150°C. If during the forging the temperature of the material drops below 880-900°C, re heating will be necessary. Cool the M2 component very slowly after forging.
Annealing
Annealing is recommended after hot working and before re hardening. Heat the M2 high speed steel to 850°C at a rate of no more than 220°C per hour. Always hold at temperature for one hour per 25mm of thickness (with two hours being minimum). Furnace cool slowly. The annealed hardness achieved should be 248 Brinell or lower.
Stress Relieving
If tools produced from M2 high speed steel are heavily machined or ground it is recommended to stress relieve after machining and prior to hardening to minimise the possibility of distortion. To stress relieve heat the component to 675-725°C and soak well (for approximately two hours), then cool in air. The tools can be finish machined before heat treatment.
