100Cr6 - B1
Base steel for the production of balls, rollers and rings for bearings, and for all small parts that must be subjected to localized and repeated loads. The high carbon and chromium content allows high hardness and perfectly transformed structures to be obtained after tempering. When it must be machined by chip removal or cold deformation, it must always be provided at the globulization annealing state.

* the hardness of the wire for the manufacture of needle roller bearings (with the “needles”) may increase up to 331HB. The maximum value of Vickers hardness (HV) should be agreed at the time of inquiry and order.
