100CrMo7 tool steels
The 100CrMo7 is chromium high-purity steels with high hardness, equivalent to tool steels, and with significant resistance to fatigue stress.100CrMo7 material is a much better alternative and the equivalent of the 100Cr6 material. Molybdenum-containing products have better hardening capacity and can be used with much larger cross-sections compared to the 100Cr6 grade.
100CrMo7 Steel equivalent standards:
| UNI/DIN | AFNOR | W-Nr | GB | JIS | W-Nr |
| 100CrMo7 | 100CD7 | 1.3537 | GCr18Mo | SUJ4 | 1.2303 |
