ASTM A532 is a standard specification for abrasion-resistant cast iron alloys used in a variety of applications that involve high wear and impact resistance. These castings are suitable for use in mining, construction, cement, and other industries where the casting is exposed to high abrasion, impact, or heat.
The ASTM A532 specification covers several different grades of abrasion-resistant cast iron, which vary in their chemical composition, microstructure, and hardness. Some of the most common grades of ASTM A532 castings include:
Ni-Hard: This grade of cast iron contains nickel and chromium, which provide excellent wear resistance and toughness. Ni-Hard castings are used in applications such as grinding mills, crushers, and cement mixers.
Hi-Chrome: This grade of cast iron contains high levels of chromium and other alloying elements, which provide exceptional wear resistance and hardness. Hi-Chrome castings are commonly used in mining equipment and machinery, where the casting is exposed to high abrasion and impact.
White Iron: This grade of cast iron is known for its high hardness and abrasion resistance. It is commonly used in applications such as pump and valve components, where the casting is exposed to abrasive wear.
ASTM A532 castings are made using a variety of casting methods, including sand casting, investment casting, and centrifugal casting. The casting process can be customized to produce castings of various shapes, sizes, and complexities that meet the customer's specific requirements.
In summary, ASTM A532 castings are abrasion-resistant cast iron alloys used in various applications where the casting is exposed to high abrasion, impact, or heat. They are available in several different grades, each with its own unique properties, and can be made using a variety of casting methods to produce high-quality, custom parts.
