Combining values from the two systems may result in non-conformance with the standard. The specifications of gray iron: The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.

While each specification may have its own distinguishing characteristics, there are also many similarities between a5771. Tensile strength, min, ksi MPa. This standard specifies that all castings shall be heat treated by annealing between and o F for 1 hour per inch of casting section and furnace cooling.

UNS numbers and corresponding American specifications. Brinell hardness range HB. There are many additional standards for Ductile Iron, some national, and others valid only within a specific technical or commercial organization.

Axtm Requirements Tensile Properties – The Ductile Iron as represented by the test zstm shall conform to the following requiremenets for tensile properties: Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes astk or new editions of the standards required in your work.

Yield strength, min, MPa. A wide variety of properties are possible. Great Lakes Castings Great Lakes Castings foundry produces gray iron castings, ferrous castings, and asmt sand castings for a variety of applications in American.


It is 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.

Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods. The castings shall undergo tension tests and impact tests, and shall conform to the following mechanical requirements: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Elongation in 2 in. Read more about subscriptions. Further values are given in annex D for guidance. Main sand casting products include truck, tractor and machinery parts, pump and valve parts, stove and boiler parts, manholes and pipe fittings. It is up to the designer to specify a set of properties – mechanical, physical, chemical or dimensional – which best suit the casting to its purpose. The values for the materials apply to castings cast in sand moulds of comparable thermal diffusivity.

Relevant wall thickness t mm. Through commitments to SPC and continual quality improvement, many foundries have developed the capability to produce castings whose higher quality can be demonstrated statistically.

ASTM A571 Grade D-2M-1

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. Mean value from 3 tests. There is own machining workshop to complete all rough machining and some finish machining works.

Range specified by agreement. 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. This service is not available if you are a URL user where you do not log in with an email address.
