Chemical composition for A709Gr50 low alloy steel (Heat Analysis Max%)

ASTM A709GR.50 steel plate is a kind of low alloy structural steel which is for building bridges in normal constructions.For a better weathering resistance,generally steel plate A709 Grade 50W is better used for outside situiations.When rolling these steel materials A709 Grade 50,for each reduction of 0.01% below the specified carbon maximum,an increase of 0.06 manganese above the specified maximum will be permitted up till maximum of 1.35%.Ourengineers suggest customer choose low temperature impacting test for steel plates A709 grade 50 at zero centigree,because these steel plates A709Gr50 normally used in this temperature.
