ASTM's ferroalloy and casting standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of iron alloys and their castings. The iron castings can be of the ferritic, austenitic, gray, cupola, pearlitic, ductile, or malleable types. The end-products to which these materials are produced from include valves, flanges, pipe fittings, plumbing systems, sanitary pipes, and pressure vessels. These ferroalloy and casting standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other end-users of cast iron and its alloys in their proper processing and application procedures to ensure their quality towards safe use.
