What is Astm A48 Class 30 and How to Download Its Pdf Specification
Astm A48 Class 30 is a grade of gray iron castings that are used for general engineering purposes where tensile strength is a major consideration. Gray iron castings are made of iron with graphite flakes in the metallic matrix, which give them a grayish color when fractured. Gray iron castings have excellent vibration and sound damping properties, thermal conductivity, compressive strength, and machinability. They are widely used in automotive, machine-tool, pump, valve, pipe, and municipal-street applications.
