M2/1.3343 Tool Steel

AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series.  The M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade T1 in most applications because of its superior properties and relative economy.

M2 Steel Round Bar:
-diameter 2 mm–200 mm
Steel Plate:
-thickness 2-200 mm x width 200-610 mm
 
Mechanical property：
-Hardness
Factory hardness: ≤255HB.
Hardness after quenching: The hardness after quenching can reach 62-66HRC.
High temperature hardness: At 600℃, the hardness can still be maintained at 48.5HRC.
-Strength
Tensile strength: about 1800 MPa.
Flexural strength: 3.5-4.0 GPa.
-Toughness
Impact toughness: 0.18-0.32 MJ/m².
Overall toughness: M2 high-speed steel has higher toughness, better than some high-hardness high-speed steels (such as M4), and is suitable for bearing impact loads.
-Wear performance
M2 high-speed steel has high wear resistance and is suitable for manufacturing cutting tools and molds.
-Thermal stability
M2 high-speed steel has good red hardness, that is, it can still maintain high hardness at high temperatures and is suitable for high-temperature cutting environments

Application

FAQ

M2 is a high-carbon, high-chromium, and molybdenum-alloyed high-speed steel that offers excellent wear resistance and toughness. It is commonly used for making cutting tools, such as drills, taps, and milling cutters.

M2 high-speed steel is known for its high hardness, excellent wear resistance, good red hardness, and the ability to maintain cutting performance at high temperatures. It also provides a balance of toughness and strength.

M2 is widely used in the manufacturing of tools that require high wear resistance and the ability to withstand high temperatures, such as drills, taps, reamers, milling cutters, and saw blades.

M2 is typically heat-treated by hardening at high temperatures followed by tempering to improve its strength and toughness. The steel is often subjected to processes like quenching and sub-zero treatment to enhance its performance further.

M2 and M35 are both high-speed steels, but M35 contains cobalt, which enhances its wear resistance and red hardness compared to M2. M35 is generally more suitable for cutting harder materials or high-performance applications. However, M2 offers a better balance of toughness and cost-effectiveness for general-purpose cutting tools.
