ASTM A709 Grade HPS 50W channel Steel

ASTM A709 Grade HPS 50W is a kind of weathering steel with Cr, Ni, Mo alloy. The ASTM A709 Grade HPS 50W channel steel shall have an atmospheric corrosion resistance index of 6.0 or higher calculated from the heat analysis in according to steel guide G 101-predictive method. When properly exposed to the atmosphere, these weathering steel sheet A709 Grade HPS 50W can be used bare and unpainted.

ASTM A709 Grade HPS 50W channel steel is a high strength low alloy structural carbon steel used in building bridge projects. Compare A709 Gr.100, and A709 Gr.50 grade, A709 Grade HPS 50W steel has a lowest yield strength in 345Mpa in usual.
Low alloy steel A709 Grade HPS 50W channel steel can be used to manufacture the plants of factory ,bridge, the common constructor and construction machinery and equipment.

Mechanical property for ASTM A709 Grade HPS 50W channel steel:
