online quote acier S690QL equivalent

The weldability of acier S690QL equivalent is good. It means that under certain process and construction conditions, acier S690QL equivalent can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe acier S690QL equivalent for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, acier S690QL equivalent based on a high starting point and high technology, the company has vigorously developed various steel products acier S690QL equivalent and deep-processed parts, steel structures, precision castings, seamless pipes.

The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. acier S690QL equivalent, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
