BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's A588 grade B structural steel plate industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate A588 grade B structural steel plate market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.
27SiMn steel plate has high strength and wear resistance, high hardenability, good machinability, moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn steel does not decrease much during heat treatment, but it has quite high strength and wear resistance, especially when water quenching still has high toughness; but this steel is highly sensitive to white spots and has temper brittleness during heat treatment. Tendency and sensitivity to overheating.
Difference between Q345R boiler vessel plate and ordinary Q345 plate, A588 grade B structural steel plate:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, A588 grade B structural steel plate.
Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. A588 grade B structural steel plate, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.
The carbon content of A588 grade B structural steel plate, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
