High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of A633 Grade C steel density, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
The difference of chemical composition between A633 Grade C steel density, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between A633 Grade C steel density, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.
In the process of A633 Grade C steel density steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose A633 Grade C steel density different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

A Uganda client purchased 2100 tons SG255 gas cylinder steel coils in 2018. It is the first company in Uganda to provide re-furbishing, re-certification and manufacturing of new lpg cylinders. They have regular demands for sg255 coils A633 Grade C steel density every 3 months. Limited by inland location, we can only ship container to mombasa, and then transfer to kampala. OurJISG3116 SG255 steel product is grade for gas cylinder steel with the tensile strength of 400MPa and the yield strength of 255MPa.
Welcome to our company to purchase, our products are exported to all parts of the world every month, the quality is guaranteed, the A633 Grade C steel density price is very preferential. Therefore, it has won great trust and praise from customers. Every month, it needs to purchase some steel plates, steel pipes and other major products. If you have any need, please contact us in time!
