Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The depth and surface hardness of the hardened case shall be as agreed upon between supplier and purchaser. The values stated in inch-pound units are to be regarded as the standard. Small cylinder blocks, cylinder heads, air cooled cylinders, pistons, clutch plates, oil pump bodies, transmission cases, gear boxes, clutch housings, and light-duty brake drums.

In like manner, light sections will contain small graphite? Gb Gc 25 Current edition approved July 29, Grade Ga Suggested Usage Brake drums and clutch plates for moderate service requirements, where high carbon iron is desired to minimize heat checking see Section 8. The relative amounts of each of these constituents depends on the analysis of the iron, casting design, and foundry techniques as they aatm solidi?

Data sheets for overmetals, plastics, ceramics, and composites. Camshaft iron with chemistry as given in Table X1. If a section solidi?
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 may be more difficult to manufacture.
We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Typical chemical analyses and mechanical properties are listed in Table X1. Typical mechanical properties for such specialized applications as heavy-duty brake drums and clutch plates are shown in Table X1. Grade General data G Miscellaneous soft iron castings as cast or annealed in which strength is not of primary consideration.
