ASME SA709 Grade HPS 70W Bridge Building Steel Plate Products Description
A709HPS70W is used for bridge carbon steel and low alloy high strength structural steel, A709HPS70W implementation standard is ASTM A709/A 709M-2007, tensile and hardness requirements to implement A6/A6M standards. The A709HPS70W has improved atmospheric corrosion resistance and is used to make road Bridges and railway Bridges (including cross-sea Bridges) with riveted and bolted welding structures.
A709HPS70W smelting method: fine grain steel operation method should be used for smelting, should be vacuum process of low hydrogen steel; Controlled soaking of ingot and billet; Controlled rolling ingot, billet, steel plate slow cooling, or combination slow cooling.ASME SA709 Grade HPS70W is exposed to low temperatures or certain environmental media for long periods of time and therefore must have good low temperature toughness and weather resistance.
