ASTM A53 is a standard specification for seamless and welded black and hot-dipped galvanized steel pipe. It has a maximum carbon content of 0.30% and a maximum manganese content of 1.20%, making it a low-carbon steel with good strength and toughness. It also has good weldability and formability and is suitable for use in high-temperature and high-pressure applications. Additionally, it has excellent corrosion resistance and can be used in outdoor environments without requiring additional protection.

The normal use cases for ASTM A53 include plumbing, heating, and air conditioning systems, as well as steam and water pipelines. It is also commonly used in the manufacturing of mechanical and pressure applications, such as boilers and pressure vessels. Its strength, toughness, and corrosion resistance make it a popular choice for a wide range of applications that require durability and reliability.

At, ASTM A53 is available in black and galvanized steel pipe. The black steel pipe is available in sizes ranging from .5 inch to 4-inch diameters and can be cut to length.
