Direct Factory M35 High Speed Steel Bar | 1.3243 SKH55 HSS Rod
M35 is a high-cobalt high-speed steel that not only has good abrasion resistance, compression resistance, and sintering resistance, but is also widely used in high-hardness cutting tools and industrial tools. We are a specialized producer of high-speed steel, our products are dedicated to use in high-temperature high-speed applications of cutting tools and blades, making us an upscale supplier.
The M35 cobalt-contained high-speed steel gets high hardness, high red hardness, and high wear resistance by heat treatment, and it has the toughness and the bending strength that is not lower than common high-speed steel, which can avoid the jam of early damage, such as die edge collapse and crack.

The heat treatment of M35 high-speed steel plays an important role in enhancing hardness, red hardness, wear resistance, and toughness. The heat treatment process generally consists of three stages: Annealing, Quenching, and Tempering. Each step is explained in more detail below:
The primary goal of heat treatment to anneal M35 is to soften the steel, which eliminates internal stress and can enhance the machinability.
In M35 heat treatment, Quenching is made by rapid cooling, its purpose is to increase the hardness, red
hardness and wear resistance of the steel.
In M35 heat treatment, tempering removes quenching stress and adjusts the hardness and toughness of steel at the same time, while ensuring red hardness and wear resistance.
