Description
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.
A179 tubes are used widely due to its excellent tensile strength and yield strength. The properties of the SA179 grade is highly unmatched, some of them are good corrosion resistance, oxidation resistance, pitting resistance, resistance to acid, crevice corrosion resistance and excellent strength.
