Brake drums and clutch plates for heavy-duty service where both resistance to wstm checking and higher strength are de? Originally published as A — 35 T. Due to its low freezing temperature for a ferrous alloy, high fluidity, and low shrinkage properties it is more readily cast in complex shapes than other ferrous metals.

The area or areas on the casting where hardness is to be checked shall be established by agreement between supplier and purchaser and shall be shown on the drawing. These include excellent machinability, high thermal conductivity, vibration dampening properties, and resistance to wear or scuffing.

The cam areas of camshaft casting shall undergo selective hardening by flame or induction hardening and shall conform to the required values of depth and surface hardness.
