ASTM A709 Grade HPS70W ,A709- hps70w Grade angle steel

High strength low alloy steel ASTM A709 Grade HPS 70W owned the minimum yield strength at 485 Mpa and tensile strength between 585Mpa and 760Mpa.So ASTM A709/ A709M standard specification for structural steel for bridges. Shanghai katalor is specialized in supplying angle steel in A709 Grade HPS 70W.

A 709 Gr.hps70w angle steel requests killed or semi-killed in manufacture. ASTM A709 Grade HPS70W Low alloy angle steels are used to manufacture the plants of factory ,bridge, the common constructure and construction machinery and equipment. ASTM A709 Grade HPS 70W’s higher strength level should result in lighter superstructures and the use of shallower girders that may permit bridge designers to reuse the existing substructure elements.
