The equivalent grades of 100Cr6 are 100CrMo7, 1.3537, CSN 19501 and 100CrMo7-3, 1.3536.

This material contains a higher molybdenum content and can be hardened to a higher hardness. Compared to the 100Cr6 grade, 100CrMo7 allows the material to be used in components with much larger cross-sections. This steel has high purity and good homogeneity, which improves its mechanical properties and increases its hardness after quenching and tempering. This steel is found in bearing components that are subjected to high speeds, pressures and temperatures, such as bearings in turbochargers, compressors, pumps or gearboxes. 100CrMo7 is also used for other machine components that require high tensile strength and hardness, such as agitators, sliders, quick couplers or locking mechanisms.

100CrMo7, 1.3537 steel contains the following elements:

• Carbon (C): 0.95–1.05%
• Silicon (Si): 0.10–0.40%
• Manganese (Mn): 0.25–0.45%
• Chromium (Cr): 1.35–1.65%
• Molybdenum (Mo): 0.15–0.25%
• Phosphorus (P): Max. 0.025%
• Sulphur (S): Max. 0.035%

Even a relatively small amount of molybdenum in the alloy significantly increases its hardness, mechanical and corrosion resistance. It has a similar effect on the material as chromium, but it increases the resistance of steel to chlorides and acids, and also increases the hardenability and creep limit.
