Hot sell sheet metal S690QL steel plate spec

ASME SA 53 seamless pipe is a low carbon S690QL steel plate spec steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized S690QL steel plate spec steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.

The Performance requirements of low alloy structural steel, S690QL steel plate spec:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

The hot rolling method is to heat the S690QL steel plate spec 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 steel plate spec rolling process is usually called semi-finished product production, also called blank production.
