Product Description
CARBON STEEL bar

Carbon steel bar is a kind of general-purpose steel bar that offers excellent formability and weldability, being used in a wide variety of applications including auto manufacturing, shipbuilding, aerospace industry, petrochemical plants, auto-power and wind-engine, metallurgical machinery, precision tools, etc.

 

A36 is an American standard specified in ASTM A36. This standard is applicable to riveted, bolted and welded structures for bridges and construction, as well as to carbon steel sections, plates and rods for general purpose structural steels. A36 is the most common used hot-rolled carbon constructional steel. It has a minimum yield strength of 36k psi and easily welding.
