GB/T 4171 Q310GNH steel sheet,ArcelorMittal USA said it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

GB/T 4171 Q310GNH steel sheet,Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). . Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.

On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project Many old customers keep asking about Din17155 steel grade-15Mo3 Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel product with low cost and better service,GB/T 4171 Q310GNH steel sheet.

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.
