EN10025-2 S235/S275/S355 Carbon Steel Coil
EN10025-2 steel coil is a low-alloy high-strength structural steel, which is made of carbon structural steel (Wc = 0.16%~ 0.2%) by adding a small amount of alloying elements. EN10025-2 steel coil has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature.
EN 10083-3 4135/4140/4142/6150 Alloy Structural Steel Coil
EN 10083-3:2006 steel is an alloy steel used for quenching and tempering. This standard regulates the technical delivery conditions of alloy steels. Under the steel 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, 27MnCrB5-2. EN 10083-3 steel plate has high strength, high toughness and good hardenability. The alloy requires high temperature preheating before welding to eliminate the stress after welding.
A285 Pressure Vessel Carbon Steel Coil
ASTM A285 Boiler Vessel Rolls are plain carbon steel used for fusion welding of pressure vessel equipment such as boilers, storage tanks, heat exchangers, etc. ASTM A285 Boiler vessel steel consists of 3 grades: Grade A, Grade B, and Grade C. The ASTM A285 boiler vessel coil has good welding performance and can meet the fusion welding requirements of pressure vessel equipment.
A709/S355J0W Carbon Steel Coil
ASTM A709 steel coil is in accordance with the standard specification for bridge structural steel, ASTM A709 steel coil is a carbon, high strength low alloy and quenched and tempered alloy steel mainly used in bridge construction. BBN offers the following 5 grades of steel coils: A709,36, 50, 50W, HPS 50W. The atmospheric corrosion resistance index of 50W, HPS 50W and HPS 70W are 6.0.
GB/T11251 1345 Alloy Structural Steel Coil
GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steel coils. GB/T 11251 Hot-rolled coil has high strength and wear resistance, high hardenability, moderate cold deformation plasticity, good cutting performance and good welding performance. During the heat treatment, the toughness of the steel decreases less. GB/T 11251 alloy steel can still maintain high toughness under water cooling conditions, but it has a tendency of overheating sensitivity, white spot sensitivity and temper brittleness.
