introduction

ASTM A36 is a carbon structural steel pipe, equivalent to Q235 material.
ASTM A36 implements the standard ASTM A36/A36M-03a. This standard is applicable to riveted, bolted and welded structures for bridges and buildings, as well as general-purpose structural steel quality carbon steel sections, steel plates and bars.
The tensile strength of A36 is 58~80 Ksi (approximately 400~550MPa), and the yield strength is 36 Ksi (approximately 250MPa).
The tensile strength of Q235 steel pipe is 370~500 MPa and the yield strength is 235MPa.
These two materials can often be substituted for each other in real life.
ASTM A36 seamless steel pipe is a material of certain shape, size and performance made of steel ingots, billets or steel through pressure processing. Most steel processing is through pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.). According to the different processing temperatures of steel, it can be divided into two types: cold processing and hot processing.ASTM A36 carbon steel pipe has good weldability and can be welded using a variety of welding techniques, such as gas shielded metal arc welding, shielded metal arc welding, and oxyacetylene welding.
