10mm-12mm thickness S690QL welding welded property

BBN STEEL supply S690QL welding plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm, single weight maximum 30.00 tons. Various special specification sheets can be rolled according to customer requirements. Types of steel products: carbon structural steel pipes, low-alloy high-strength steel sheet, steel angles for bridges, steel section for building structures, steel plates for shipbuilding and offshore platforms, steel for boilers and pressure vessels and alloy structures.

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep S690QL welding processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and S690QL welding steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as S690QL welding high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold

Oxygen is a harmful element in S690QL welding steel. With the increase of oxygen content, the strength of S690QL welding steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S690QL welding steel.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
