ASTM A74-SV Grey Cast Iron Pipe

Description

ASTM A74-SV refers to the standard specification for gray iron castings for valves, flanges, and pipe fittings. This specification covers gray iron castings used in various industrial applications, such as plumbing, water distribution, and wastewater systems.

Gray cast iron is a type of cast iron that contains graphite flakes, which give it its characteristic gray appearance. It has excellent machinability and good wear resistance, making it suitable for applications where strength and durability are required.

ASTM A74-SV establishes the requirements for chemical composition, tensile strength, hardness, microstructure, and other mechanical properties of gray iron castings used for specific purposes. This standard ensures that the castings meet certain quality and performance standards, making them safe and reliable for their intended applications.
