What is S690QL1 chemical composition equivalent Indian material

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. S690QL1 chemical composition steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished S690QL1 chemical composition steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing S690QL1 chemical composition steel plate distribution services, so as to save customers manpower and material resources.
