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.
