M42 steel (W2Mo10Cr4Co8) is a high-cobalt toughness high-speed steel, mainly used for high-toughness precision wear-resistant hardware cold stamping dies, and can also be used for cutting tools and knife cooling.
The M42 steel has a high hardness of 68~70HRC, good heat hardness, high temperature hardness and easy grinding. but the toughness is slightly poor, and the lower limit should be used for quenching. Due to its good grindability, it can be used to manufacture a wide range of high precision and complex tools.

The hardening and tempering process can greatly improve the hardness and wear resistance, and toughness of M42 high-speed steel. The standard heat treatment process is shown below:
To anneal the steel, stress relieve, and improve machinability.
Increases hardness and wear resistance through rapid cooling
Gets accomplished after quenching to relieve internal stress and adjust hardness for improved performance.
Remarkable Hardness:
65-67 HRC, very good for demanding cutting tasks.
Superior Wear Resistance:
Dense matrix structure designed for large-scale, long-time cutting.
Stress-relieved material that can withstand high impact for new machining styles.
Strict control of the cooling speed of quenching to prevent uneven hardness or cracking.
Minimum two cycles to remove internal stress and increase toughness.
Too much heat raises the risk of the grain getting scorched and burned.
Better value for money
M42 high-speed steel provides proper quality, as Japanese, European, and American brands, but at a more competitive price. Through an intense smelting process and strict quality control, we provide great convenience to our clients with an excellent quality/price ratio.
Our M42 steel features a consistent microstructure and refined carbide distribution with the use of FAF + IF + VD + RS ESR technology, which enables high toughness and wear resistance.
Advanced Heat Treatment:
We use an advanced heat treatment process that trains toughness and hardness, severely increasing their performance under high stress and high temperature conditions.
Consistent Material Quality:
From raw material selection to final product manufacturing, we own the production process from start to finish. This bodes for uniform quality and performance from every batch.
International Standards Compliant:
Use of domestically produced M42 high-speed steel has been adopted for our products, and the quality standard of products meets the domestic standard GB/T 9943-2008 as well as the international standard AISI M42, JIS SKH59, and DIN1.3247, providing the customers with an international sense of security.
Research and Development:
Our company follows the "13th Five-Year Plan" of the National Ministry of Science and Technology, and enjoys government funding and technical support, which can ensure our sustained innovation.
Our unique technology:
We can create a proprietary rapid solidification electro-slag remelting (RS ESR) process in partnership with Shanghai University and Beijing Iron & Steel Research Institute. However, for high-performance applications, it is crucial to improve the purity of the materials and achieve a consistent distribution of the carbides
We have independently developed a spray forming process for high-speed steel, in cooperation with the Baosteel Groupand other advanced enterprises. it is the only one for this new manufacturing process of M42 steel in the whole of china.
Working with M42 High-Speed Steel in Application:
Applicable to the production of drill, tap, screw die, milling cutter, gear cutter, cold die mold and other cutting tools, and molds with high wear resistance and strength.
Precusuib Dies
Best for punches, stamping dies, and forming tools in high-stress applications.
M42 vs Other High Speed Steels
M42's cobalt-enhanced makeup also gives it hot hardness and wear resistance superior to many other grades, especially in high-stress conditions.
Are M42 materials customizable?
As a manufacturer of raw materials, our main mindset includes the demand for our high-speed steel raw materials, but we also provide semi-finished and finished product customization services according to customer requirements, such as size and surface requirements, repeatability, and high-performance raw materials.
Has your M42 high-speed steel been certified for passing quality?
M42 Hss is are ISO 9001 quality management system certified material and is closely monitored through each production cycle before it leaves the factory, as numerous internal tests are performed to confirm material performance meets industry standards and customer expectations.
