Common specifications of S690QL high tensile steel

16Mo3 steel plate is used for pressure vessel, and it is EN10028-2 designated chromium molybdenum steel alloy that is used for increasing working temperature. 16Mo3 steel plate is used to make industrial boilers and pressure vessels for the petroleum, natural gas and chemical industries. 16Mo3 steel plate is different from other raw materials in welding: S690QL high tensile steel preheating shall be carried out first, and the weld joint shall be kept for about 30 minutes after the completion of welding.

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel S690QL high tensile steel products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our S690QL high tensile steel business. We also provide third-party inspection and approval services and inventory management for our customers.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S690QL high tensile steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S690QL high tensile steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

After extrusion, the S690QL high tensile steel 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.

Provide special product requirements to meet the personalized needs of customers.
