A 572 Grade 50 high-strength low-alloy columdium-vanadium structural steel plate which is according to ASTM A 572/A 572M standard to produce. A 572 Grade 50 [345] is intended for riveted, bolted or welded structures. It is applied in welded bridge construction, where notch toughness is important, notch toughness requirements are to be negotiated between the purchaser and the producer. The available size is (T*W*L): 6--100mm * 1500--3700mm * 3000--18000mm. The ordinary delivery condition is hot rolled. But you can request to choose others such as normalized. Charpy V-Notch impact test, maximum tensile strength can be choosed.
