ASTM A871 material is a kind of low alloy high strength structural weathering resistance steel,or corten steel,or atmosphere corrosion resistance steel.There is two grades they are A871 Gr 60 and A871 Gr 65.ASTM A871 has for types:A871 TYPE I
JIS G 3125 SPA-C corten steel sheet anti corrosive steel SPA-C corten steel sheet resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of SPA-C corten steel sheet can form a coating of dark brown oxidation, which inhibits deeper penetration, so SPA-C corten steel sheet save the cost of need for painting and costly rust-prevention maintenance over the years.
weathering steel is that it doesn't have to be painted, In suitable environments weathering steel forms an. adherent protective rust patina, that inhibits further corrosion. The corrosion rate is so low that bridges. fabricated from unpainted weathering steel can What is the welding procedure for - BEBON steel expertDifferent from ordinary steel plates, ASTM A588 Gr.A weathering steel has good corrosion resistance. Under severe weather such as acid rain, many buildings began to show different degrees of corrosion, which not only affected the buildings, but also affected the people in the buildings. At the same time it also brings some security risks. 1.
