ADI (Austempered Ductile Iron) Casting News & Technical Articles – SMEMACH

​Today, metal materials are widely used in aerospace, automobile manufacturing, mechanical processing and many other fields. The stability of product quality and performance is crucial. Metallographic Testing, as a method of in-depth observation and analysis of the microstructure of metal materials, is like a precise scalpel, providing a key basis for the quality control of metal materials.

In the production, research and development, and quality control of metal products, tensile testing is a crucial experiment. It is like a precise ruler that can accurately measure the mechanical properties of metal materials under stress, providing a key basis for material selection, process optimization, and product safety and reliability assessment.

In today's manufacturing industry, where competition is fierce and product quality requirements are almost stringent, accurate dimensional measurement is like a solid foundation, supporting the building of product performance, reliability and consistency. Coordinate measuring machine (CMM) testing is the core technical means to ensure that products meet strict quality standards and safeguard the quality pursuit of many companies.

ISO 17804:2005 "Classification of Cast Austempered Ductile Iron" is an ISO standard rather than a standard from a single country. This standard specifies the grades and corresponding requirements for austempered ductile iron, and classifies austempered ductile iron based on the mechanical properties measured from machined test pieces. These test pieces may also be made from separate cast samples, cast sample(s), or cut from castings. And it also sets up two levels according to the division of hardness function. ISO 17804:2005 has been replaced by ISO 17804:2020, which is the current version. But ISO 17804:2005 still has a certain historical significance and reference value in the foundry industry.

Now, we’ll study the international American ADI Austempered Ductile Iron standards in chronological order for today.
