Since iron metallurgy began, constant effort has been expended to improve the normal product. A major method of improving the metallurgical properties of iron and steel is by alloying with other elements. Committee A-9 of ASTM on Ferroalloys and Alloying Additives is devoted to standardizing these alloying additives so that all within the industry will obtain comparable products.
The concept for A-9 occurred in 1923 when the first standards for ferroalloys were established. The next 50-odd years of operation have seen these standards expanded, deleted, altered, and new additions created to reflect the changes in steel technology. The complexity of this technology has involved A-9 with other ASTM committees and also with other domestic associations, not to mention the interrelationship with comparable foreign associations to establish worldwide standards on ferroalloys.
To prepare for the future of ferroalloys, A-9 will incorporate various facets into their present standards to constantly improve their performance and acceptance by not only domestic steel industry but worldwide as well. The flexibility of the committee's structure and membership permits attaining this goal.
