American Society of Automotive Engineers Inc. However, most of the specifications identify either minimum properties, or ranges of properties, inferring that all castings whose properties either exceed the minimum or awtm anywhere within the range, are equally acceptable. Further values are given in annex D for guidance.
The castings shall conform to the following chemical requirements: Their castings are all in the gray iron classeswith a base iron tensile of 30, It aetm the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The values for the materials normally apply to castings with thicknesses between 30 mm and mm and with a mass greater than kg or when the relevant wall thickness may vary between w571 mm and mm.
Conversions for SI, metric non-SI, and non-metric units are given at the end of this section to assist in comparing specifications. The mechanical properties are given for information only.
Mean value of 3 pieces J. FCAD min. Yield strength, Proof stress, R po. Historical Version s – view previous versions of standard.
Over 30, up to and incl. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Dandong Ruiding Foundry Main casting materials: GLC provides castings in weights ranging from a few ounces up to fifty pounds. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Minimum tensile strength R m MPa. The castings shall have a carbon equivalent of 3. Yield strength, min, psi. The benefits of a subscription: Minimum impact resistance values measured on V-notch test pieces machines from separately cast samples.
The raw materials and production methods used by the foundry to provide conforming castings are not normally restricted by the designer or the specification unless the specification includes such instructions, a751 the designer and foundry agree to append additional instructions s571 a specification. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Deivam Foundry Deivam Foundry is one of the leading manufacturers of steel castings spheroidal graphite iron castings and sand castings.
Tensile strength, R m1 min.
UNS numbers and corresponding Ashm specifications. It allows to quickly produce a wide range of casting sizes on one production line.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Silicon-Molybdenum Ductile Irons C. The castings shall be made in the electric-arc furnace, induction furnace, cupola, or any other furnace which is capable of producing castings. Mean value from 3 tests. Specifications should be chosen carefully and used sparingly to ensure that they adequately define the designer’s needs without adding superfluous constraints which needlessly restrict the suppliers’ options, complicate the casting process and increase the cost of the casting.
