The properties of a cast-on test piece cannot reflect exactly the properties of the casting itself, but can be a better approximation than those obtained on a separately cast sample. Sand Casting Foundries Introducing some sand casting foundries in USA and China, whose main products are various gray iron, ductile iron and steel sand castings. Yield strength, Proof stress, R po. Impact strength energy loss J.

ASTM A571/A571M:01(2011)

A wide variety of properties are possible. While not itself a specification, the UNS designation is gaining some degree of acceptance in North America as a useful means of simplifying and correlating the various existing specifications. A Additions of 0. Mechanical properties of separately cast test sample.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods.


UNS numbers and corresponding American specifications. Introducing some sand casting foundries in USA and China, whose main products asrm various gray iron, ductile iron and steel sand castings. Mean value from 3 tests. A fully automated FBO-III Sinto 20″ x 26″ molding machine and handling system that produces casting with unmatched quality During the entire process, lab checks are made on metal and casting sand to assure high quality finished products.

Grade Tensile strength, R m1 min. Casting Company pours a wide variety of carbon, low alloy steel along with grey and ductile iron in weights ranging from 10 aetm 8, pounds. Before using any specification, the designer should obtain a complete copy of the a751 issue from the specifying body to familiarize himself with both the properties specified and the conditions under which they are to be measured.

Melting is accomplished in three ton coreless furnaces. Silicon-Molybdenum Ductile Irons C.

There are many additional standards for Ductile Iron, some national, and others valid only within a specific technical or commercial organization. The benefits of a subscription: It is up to the designer to specify a set of properties – mechanical, physical, chemical or dimensional satm which best suit astn casting to its purpose. Historical Version s – view previous versions of standard. Whatever the method used for obtaining the castings, the grades are based on the mechanical properties measured on test pieces taken from samples separately cast in a sand mould or a mould of comparable thermal diffusivity.


Conversions for SI, metric non-SI, and non-metric units are given at the end of this section to assist in comparing specifications. This abstract is a71 brief summary of the referenced standard.
