ASTM A709M HPS50W structural steel

Shanghai Katalor steel offer ASTM A709M HPS50W structural steel stock in China.
ASTM A709 HPS50W steel is American standard specification for for structural steel in bridge with hot rolled processing. Therefore, ASTM A709M HPS50W structural steel is widely used in bridge constructions to atmospheric corrosion resistance. Furthermore, ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of ASTM A709M HPS50W structural steel in most environments is substantially better than carbon steel with or without copper addition. ASTM A709-50W shall have an atmospheric corrosion index of 6.00 or higher.
ASTM A709M HPS50W structural steel 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 A709M HPS50W structural steel are in a variety of sizes and thicknesses, and are available as ex–stock or directly shipped from the mill. As with all our steels, our plates come with mill test certification, stampings and fully traceable. We can arrange for a variety of tests to be performed on the material if specified.More about ASTM A709M HPS50W structural steel,please contact Shanghai Katalor steel.
