A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. Corten B plate thickness, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. Corten B plate thickness, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
Peritectic reaction often occurs in the process of cooling and solidification of wear-resistant steel plate, Corten B plate thickness, and accompanied by this reaction, there will be greater volume change and linear shrinkage, which is mainly due to the hot cracking of continuous casting slab in the casting process. In the mold, the heat load transmitted from the billet is too much or uneven around the meniscus of molten steel, resulting in uneven heating, which is more likely to produce longitudinal cracks.
Corten B plate thickness, A572 Grade 50 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A572 Grade 50 steel coil thickness should not exceed 25 mm. For A572 Grade 50 steel, the C element content is 0.23%, the Si element content is 0.4% max, the Mn element content is 1.35% max, the P element content is 0.004% max, the S element content is 0.05% max, the V element content is 0.06%, the Ni element content is 0.015%, the Co element content is 0.05%.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another Corten B plate thickness magnificent projects.
