ASTM A588 Grade B Introduction
ASTM A588 Grade B corrosion resistant steel is a weather resistant steel which could more accurately be termed as an "Atmospheric Corrosion Resistant Steel".
It is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. Its chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.

ASTM A588 Grade B Application
The fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneys and boilers.
Construction of tanks, containers, bridges, frame structures, vehicles, etc with the request of welded, bolted, etc.
The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes protects the steel beneath it. The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.
