S690QL weldability vs s355jr steel material

ABS AH36 ship steel plate is a structural steel with high strength for hull. Shipbuilding steel generally refers to the steel used for hull structure, which refers to the steel used to make the hull structure produced in accordance with the requirements of the classification society. This kind of product is often ordered, scheduled, and sold as special steel, ship steel plates, section steel, S690QL weldability, angle steel bars, bulb flats.

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S690QL weldability production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of S690QL weldability leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

The hot rolling method is to heat the S690QL weldability steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of S690QL weldability rolling process is usually called semi-finished product production, also called blank production.

The chromium plays an important role in S690QL weldability, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
