Nov 17, 2025 Leave a message

What is A179 material?

ASTM A179: A179 is a low-carbon steel grade specifically designed for heat exchanger and condenser tubes. It offers excellent thermal conductivity and is suitable for both seamless and welded applications.

 

What is ASTM A179 specification?

ASTM A179 (SA 179) standard specification covers seamless cold drawn low-carbon steel pipe, for tubular heat exchanger, condensers, and other similar heat transfer equipment. The ASTM A179 tube covers the OD from 1/8" to 3", which is 3.2m m to 76.2 mm.

 

What is the difference between ASTM A106 and A179?

A179 is a low carbon steel tube that is used for heat exchangers and condensers, while A106 is a seamless carbon steel tube that is used for high-temperature service.

 

What is the chemical composition of A179?

ASTM A179 Low Temperature Carbon Steel Tube
Chemical composition contains carbon, manganese, phosphorus, and sulfur. Test required: hardness test, flattening test, flaring test, flange test, and hydrostatic test.

What is the hardness of A179?

The ASTM A179 tubes shall have a hardness number not exceeding 72 HRB.

 

What is SA 179 material?

SA179 tubes are made of carbon steel with low carbon content, offering excellent heat transfer, high corrosion resistance, and durability. They are widely used in condensers, heat exchangers, and other high-pressure applications.

 

What is the difference between ASTM a214 and A179?

SA-214 and SA-179 are both carbon steel pipe standards for heat exchangers and condensers. The core difference is the different manufacturing processes. SA-214 uses the ERW process, while SA-179 uses the seamless cold drawing process.
