Product Description

 ASTM A179 20# black cold drawn carbon seamless steel tube used in gas, oil, liquid

ASTM A179 20# black cold drawn carbon seamless steel tube  is a standard published by the American Society for Testing and Materials that deals with the specification requirements for seamless medium carbon steel boiler tubes. The ASTM A179 20# black cold drawn carbon seamless steel tube  standard is suitable for the manufacture of seamless medium carbon steel boilers and superheater tubes for high pressure boilers, ultra-high pressure boilers and ultra-high temperature furnaces. Here are some of the features and applications of ASTM A179 seamless tubing: ASTM A179 seamless pipe is usually made of low carbon steel (C ≤ 0.27), with good weldability and mechanical properties. The material is suitable for high temperature and high pressure environment, and has good corrosion resistance and oxidation resistance. Specification requirements: ASTM A179 standard specifies the seamless pipe size, chemical composition, mechanical properties and testing requirements in detail. The outer diameter, wall thickness, length, straight or curved pipe and other specifications of the pipe are clearly specified.
