In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product ship construction use A131 DH36 structural steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel ship construction use A131 DH36 structural steel supplier in the world.
SA516Gr60 meets the requirements of (ASME) ASTMA516/A516M standards, and meets the needs of oil gas with high content of sulfur and hydrogen, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing equipment life. The steel ship construction use A131 DH36 structural steel has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layer cracking performance, microalloying, high purity, low carbon equivalent, and strong resistance to sulfur and hydrogen.
EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.
Although ship construction use A131 DH36 structural steel, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.
As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of ship construction use A131 DH36 structural steel, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate ship construction use A131 DH36 structural steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
