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:

100CrMo7 steel mechanical properties:
Hardness in spheroidized annealing condition +AC: < 217 HB

Hardness in spheroidized annealing condition after drawing +AC+C: < 251 HB

Hardness of tubes and sleeves <321 HB

Density ρ 7,79 g/cm3

1.3537 bearing steel

1.3537 steel is bearing steel. Small amount of Chromium and trace amounts of Molybdenum provides for some carbide formation, and it can hold decent polished edge.It has characteristics similar to 100Cr6 steel(1.3537 vs 100Cr6). The addition of molybdenum guarantees toughness for diameters up to 200mm.it has good wear resistance, with good non-deformability.

1.3537 Steel equivalent standards:

1.3537 steel  mechanical properties:
Hardness in spheroidized annealing condition +AC: < 217 HB
Hardness in spheroidized annealing condition after drawing +AC+C: < 251 HB
Hardness of tubes and sleeves <321 HB
Density ρ 7,79 g/cm3

1.3537 steel Application

1.3537 works better  for small to medium knives, after appropriate heat treatment might do well in a larger blade. It’s suitable for the construction of bearings,cylinders, small rolling mills, knives, etc.

100Cr6 bearing steel

The comprehensive properties of 100Cr6 bearing steel are good. After quenching and tempering, the hardness is high and uniform, the wear resistance is good, and the contact fatigue strength is high. The steel has good hot workability and good machinability after spheroidizing annealing. 100Cr6 has better toughness, better tempering stability, smaller deformation and better hardenability than chromium steel.

100Cr6 steel equivalent grade:

100Cr6 mechanical properties:

Bulk modulus:140 GPa

Shear modulus:80 GPa

Elastic modulus:190-210 GPa

100CrMn6 bearing steel

100CrMn6 is a kind of bearing steel, Chromium ball bearing steel.

100CrMn6 steel equivalent grade:

100CrMn6 mechanical properties:

Tensile strength:115-234MPa

Yield Strength:154MPa

Elongation:56δ5≥(%)
