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 astm 633c industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate astm 633c market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

ASTM A387 Grade 91 astm 633c is a high level steel grade for outstanding heat and anti corrosion and oxidation resistance characteristics, it astm 633c satisifies most applications in fierce working environment with higher requirements.

S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, astm 633c, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.

astm 633c, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
