Introduction to A36 hot rolled steel plates

ASTM A36 steel plate is a standard carbon steel material specified by the ASTM (American Society for Testing and Materials). It is one of the most commonly used steel grades for structural and fabrication purposes.

“A36” refers to the standard specification under ASTM A36.

“Hot rolled” means the steel was rolled at high temperatures (above recrystallization temperature), resulting in a rougher finish but better workability for forming and welding.
