Tensile strength R m min. Mechanical property values are given in the units normal to the particular specifying body. 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.

Daily capacity exceeds tons. The material designation is in accordance with EN 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. Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Other Standards This section also summarizes the national standards for Ductile Iron for the other major industrialized countries and the international ISO standard.

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. FCAD min. B Not intentionally added. 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. Introducing some sand casting foundries in USA and China, whose main products are various gray iron, ductile iron and steel sand castings.


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. Mean value from 3 tests. The other standards cover austenitic and special Ductile Iron applications.

UNS numbers and corresponding American specifications. There are many additional standards for Ductile Iron, some national, and others valid only within a specific technical or commercial organization. Start Webshop Product catalog Product presentation.

Brinell hardness range HB. 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. Bremen Castings Bremen Castings, Inc. Chemical Requirements The castings shall conform to the following requirements for chemical composition Note 3: Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.

Designers should take advantage of these capabilities to obtain assured quality which is superior to that required by specifications. The production scope of the castings: Minimum impact resistance values measured on V-notch test pieces machines from separately cast samples. FCD min. 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, or the designer and foundry agree to append additional instructions to a specification.

Before using any specification, the designer should obtain a complete copy of the current issue from the specifying body to familiarize himself with both the properties specified and the conditions under which they are to be measured. Austenitic Ductile Irons D.

This ensures that you are xstm up-to-date and saves you both time and money. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.


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 range, are equally acceptable.
