41Cr4 Scr440 5140 Alloy Steel Plate 10 - 140mm Cutting
41Cr4 Alloy Steel Plate Scr440 5140 Steel Plate 10 - 140mm Steel Plate Cutting
41Cr4 steel is a Chrome Manganese steel used in the manufacture of quenched and tempered bars where strength required is less than SAE 4140 steel bars.
It is also suitable for induction hardening with a minimum hardness of 52HRC.
The cold-upsettable steel 41Cr4 can be cold-formed with suitable tools with a low to medium rate of forming according to the usual forming methods on single-stage and multi-stage presses. It is used for normed screws and screws manufactured according to drawings of strength class 8.8 in the thick dimension range. Also used for high-strength parts manufactured according to drawings (eg. ball studs).
