The castings shall undergo tension tests and impact tests, and shall conform to the following mechanical requirements: Complete specifications may be asym from: The use of standard specifications simplifies the purchase of castings from multiple suppliers because it defines a standard casting whose properties meet the designer’s needs, regardless of where, or how the castings were produced.

Ductile Iron Data – Section 12

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 atsm. Introducing some sand casting foundries in USA and China, whose main products are various gray iron, ductile iron and steel sand castings.

The other standards cover austenitic and special Ductile Iron applications. Boiling Point o F. Such instructions should be used judiciously, because they almost invariably increase the casting cost and restrict the number of foundries which can provide competitive bids.

Austenitic Ductile Irons D.

ASTM A Manufacturer, Supplier,Exporter

However, most of the specifications identify either minimum properties, or ranges of properties, inferring that all castings whose properties either exceed the minimum or lie anywhere within the astk, are equally acceptable. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.


Minimum properties are specified by agreement between manufacturer and purchaser. Test Coupon Section Thickness.

You need to log in before adding standards to the monitoring service. Treatment laddle – 3 Nos Capacity – Cupola 1. Tensile Requirements for Special Applications. English, SI units, and non-SI metric units. Charpy V-notch, ft-lbf min, average 3 tests. Melting is accomplished in three ton coreless furnaces. Minimum impact resistance values in J. Great Lakes Castings Great Lakes Castings foundry produces gray iron castings, ferrous castings, and green sand castings for a variety of applications in American.

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.

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.

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. Mean value from 3 tests.
