ASTM A709 Grade 50 structural stee lproducts furnished under this specification shall conform to the requirements of the current edition of Specification A6/A6M, for the specific structural product ordered, unless a conflict exists in which case this specification shall prevail.
When rolling these steel material 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%. Our engineers 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.
