45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of ship construction use A131 DH36 structural steel, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.
On March 17 th 2018, our Sudan customer purchased the SG295 cylinder steel coils through other country such as UAE,Turkey before they cooperate with us. After they research our regular customer in Uganda, UAE, and his friends in China, he is satisfied with our company. Our produced SG295 cylinder steel is mainly used to fabricate low temperature pressure vessels like gas cylinder. The customer is very satisfied to our ship construction use A131 DH36 structural steel quality control and professional arrangement for the SG295 steel order.
Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. ship construction use A131 DH36 structural steel, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.
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.
