■ Overview
ASTM A709GR.50 steel angles ASME SA709 Grade 50 angle bars is a kind of low alloy structural steel which is for building bridges in normal constructions.Xinsteel’s engineers suggest customer choose low temperature impacting test for steel angles A709 grade 50 at zero centigree,because these angle steels A709Gr50 normally used in this temperature.
