CrWMn is the most commonly used high-carbon alloy tool steel to make molds.
As improved type of 9CrWMn die steel, CrWMn is known as "non-deformable steel" and has a long history of application and widely use in China.
Hardenability, hardening capacity, toughness, wear resistance, and controllability of deformation after heat treatment are better than T10A steel.
Because tungsten forms carbides, the steel has more excess carbides, higher hardness and wear resistance after quenching and low-temperature tempering than chromium steel and 9SiCr steel.
In addition, tungsten also helps to preserve the fine grains, so that the steel obtains better toughness.
The steel is widely used to machine thin steel plates. It is the basic material for non-ferrous metal light-loaded and complex-shaped cold stamping dies, especially in the fields of clocks, instruments, toys, and food industry.
The steel can be used to make complex shapes of blanking dies of thickness<1mm, such as concave dies, convex dies and insert dies.
It is used for concave dies, convex dies and insert dies in bending dies that require high wear resistance and have complex shapes.
It is used for concave dies and convex dies in cold extrusion dies for aluminum parts.
It is used for the cold extrusion concave die of copper parts, and cold extrusion convex and concave dies of steel parts
Focus on manufacturing special steel cast and forged
components for more than 25 years.
