Alloy gray iron automotive camshafts of grade designation Gd shall conform to the required values of casting hardness, chemical compositions of chromium, molybdenum, and nickel and microstructure.
These should appear as product speci? These may be annealed castings for exhaust manifolds in order to avoid growth and cracking due to aatm. Originally published as A — 35 T. Grade General data G Miscellaneous soft iron castings as cast or annealed in which strength is not of primary consideration. Used in automotive, truck, and tractor brake and clutch applications.
Drillings are not reliable because of the probable loss of graphite. The composition ranges for such special applications as heavy duty brake drums and clutch plates and camshafts are shown in Table X1.

When higher strength is obtained by a reduction in the carbon or carbon equivalent, castings are more difficult to machine, have lower damping capacity, higher modulus of elasticity, and asfm be more difficult to manufacture. This specification applies to gray iron castingscast in sand molds, used in the products of the automobile, truck, tractor, and allied industries.
