Material and Hardness
All the Circlips are manufactured from steel of grade such as 70C6 or 75C6 confirming to IS : 2507 - 1975 specification for cold rolled steel for springs (first revision)
Hardness of Circlip is between 460 to 580 HV (Corresponding to 46 to 54 HRC)
Finish
Unless the purchaser specifies any alternative finish, the circlip shall be chemically of thermally blackened.
Note
In case of Circlip with electroplated surface protection, the upper limit of thickness 'S' may be exceeded according to the film thickness of the plating required. This shall be taken into account in the design of the groove.
