Introduction
ASTM A283 /
A283M covers low and intermediate tensile strength carbon steel plates intended
for general structural and engineering applications. These plates are designed
to provide good formability, weldability, and moderate strength for use in
non-critical pressure and structural applications.
ASTM A283
carbon steel plates are widely used in fabrication, construction, and
industrial projects where cost-effectiveness and ease of processing are
important.
