Our gas cylinder steel materials are hot selling in 2019. The order quanitity for gas cylinder steel coils and sheets amount to 10,000 tons. Among them, a large portion of the gas cylinder steel coils and sheets are exported to Uganda, Kenya and so on Africa countries for gas cylinder production companies. Now our gas cylinder steel has taken a large market share in local. We supply both gas cylinder steel coils and gas cylinder steel sheets. The dimension is customizable. shipbuilding use GL-D hull structural steel
Shipbuilding use GL-D hull structural steel,Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
Shipbuilding use GL-D hull structural steel,The thickness of our pressure vessel plates, generally ranges 5 to 200mm According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel,shipbuilding use GL-D hull structural steel.
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 quality control and professional arrangement for the SG295 steel order.

Shipbuilding use GL-D hull structural steel,40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
After extrusion, the tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
