Production growth of S690QL steel mechanical properties mill slows down

ASTM A514 Gr Q is quenched and tempered alloy steel with high yield strength and tensile strength, good notch toughness and corrosion resistance. Under the premise of meeting the strength requirements and not increasing the C content, S690QL steel mechanical properties, A514 Gr Q steel can improve its hardenability and anti-tempering softening tendency by adding appropriate amounts of Cr, Mo, V, Cu and other elements.

Heat treatment is a very important process to improve the performance of S690QL steel mechanical properties etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the S690QL steel mechanical properties steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

S690QL steel mechanical properties, Welded pipe plays an important role in modern industrial production and engineering construction, and has become one of the irreplaceable steel pipe products. Welded pipe is a kind of steel pipe made of rolled plate and steel plate after crimping and forming. Therefore, the diameter of welded pipe can be made very large and can be made according to the requirements of customers. Welded pipes can be used for water diversion, transportation of gas, air, oil and heating steam and other generally lower pressure fluids.
