XW-5 Tool Steel Mechanical & Performance Properties

1. Extremely high wear resistance: The combination of high carbon and high chromium with tungsten to form a hard carbide network is suitable for long-life blanking or shearing tools.
2. Strong compressive strength: It can still withstand a large compressive load in the hot state. The common compressive strength after quenching with HRC 62 is about 2200 MPa.
3. Good resistance to tempering softening: It has excellent stability after heat treatment and is not prone to significant hardening due to changes in tempering temperature.
4. Hardness range: After quenching at 920-980 °C and tempering with heating, it can reach HRC 64-66. It can also be hardened to HRC 65.5-66.5 at 960-1000 °C.

XW-5 Tool Steel Product Applications

It is widely used in cold working tools with extremely high wear resistance requirements, such as:

1. Blanking dies, shearing dies, trimming knives and cutting tools for thin and hard plates.
2. Long-term operating stamping dies, deep drawing dies and cold extrusion dies.
3. Making ceramics, grinding plastic molds, measuring processing tools, etc.
