ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. A709 grade 50 bridge steel plate, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, A709 grade 50 bridge steel plate etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.
The main raw material of A709 grade 50 bridge steel plate, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
