What is S690QL materiale equivalent material in JIS standard

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of S690QL materiale steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special S690QL materiale materials and specifications can be ordered in advance.

A514 Gr P steel plate is high strength quenched and tempered alloy steel, which is an American standard steel plate. S690QL materiale, A514 Gr P steel plate has high tensile strength and yield strength. It is commonly used in the manufacture of offshore platform, mining and various construction machinery and other structural parts. With the development of industry and the discovery of more and more offshore oil, the market demand for A514 Gr P steel plate is increasing.

Our quality control department will do inspection for details of the steel materials S690QL materiale before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The weldability of S690QL materiale is good. It means that under certain process and construction conditions, S690QL materiale 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.
