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. Heavy-duty irons for such service require high carbon contents for resistance to thermal shock and to minimize heat checking.
No other units of measurement are included in this standard. Data sheets for overmetals, plastics, ceramics, and composites.
A — 83 Reapproved Standard Speci? These may be annealed castings for exhaust manifolds in order to avoid growth and cracking due to heat. This specification covers gray iron castings for products of the automobile, truck, tractor and allied industries. These include excellent machinability, high thermal conductivity, vibration dampening properties, and resistance to wear or scuffing.
We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Questions or comments about MatWeb? Typical chemical analyses and mechanical properties are listed in Table X1. See Method A for information concerning the B transverse test bar and the transverse test. The values stated in inch-pound units are to be regarded as the standard.
ASTM A – Standard Specification for Automotive Gray Iron Castings This specification applies to gray iron castingscast in sand molds, used in the products of the automobile, truck, tractor, and allied industries. Asttm abstract is a brief summary of the referenced standard. 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 aztm elasticity, and may be more difficult to manufacture.
