AISI M2 Steel Factory Supply offers high-speed tool steel known for its exceptional wear resistance and toughness. This alloy steel, also referred to as SKH51 and 1.3343 steel, provides outstanding hardness and red hardness, making it a reliable choice for cutting tools that endure large impact forces. With its balanced carbon composition, it has become the preferred material for manufacturing various industrial tools, including pinion cutters, planers, milling cutters, and drill bits.

1.3343 Steel Characteristics
Hardness (factory state): ≤255HB
Curing Temperature: 1220℃-1240℃
Hardness (after heat treatment): ≤ 63 HRC
It is a good choice for cutting applications due to its high wear resistance and toughness.
Carbide evenly distributed and high toughness.
Can be used to make milling cutters, reamers, broaches, gear cutters and other industrial tools.

The material undergoes processes like ESR, hot rolling, and forging to ensure a consistent output. Its hardness in the factory state is ≤255HB, and it can achieve a hardness of up to 63 HRC after heat treatment. Due to its even carbide distribution, this steel maintains excellent thermoplasticity and toughness, which are crucial for applications requiring high wear resistance.
