The company cooperates with CCS F40 offshore platform steel plate steel plants such as Maanshan Iron and Steel, Youdan, Liugang, Tangshan Iron and Steel, Xinyu, Jinan Iron and Steel, Shougang, Shagang, Rizhao, Pinggang, Xicheng, Dachang and other steel mills all year round. Alloy plate, CCS F40 offshore platform steel plate boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.
The mechanical properties of CCS F40 offshore platform steel plate steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel CCS F40 offshore platform steel plate to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate CCS F40 offshore platform steel plate should also have good welding performance and low notch sensitivity.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, CCS F40 offshore platform steel plate, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.
The chemical composition difference between CCS F40 offshore platform steel plate, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between CCS F40 offshore platform steel plate, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
