Hot Rolled Steel Plate 1/2" x 8" x 8" steel S690QL Carbon Steel

steel S690QL, Manganese steel plate is a low alloy high strength steel plate with good weldability. Manganese steel plate is the main material of general pressure vessel. Manganese steel plate is mainly used to make engineering structural parts, roof beam of workshop and tower crane tower body. Manganese steel plate has high rupture strength and creep strength at high temperature and good impact toughness at low temperature. High strength steel is a kind of wear-resistant steel for heavy industry. Its application fields include quarrying, mining, mining, coal industry, casting and steel industry, etc.

The Performance requirements of low alloy structural steel, steel S690QL:(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 steel S690QL steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the steel S690QL internal quality of the steel.

If you are in the search of best quality of steel S690QL structural steel plate then you have landed on the right place. These high quality structural steel plates are used for a long time as they have a long life due to their best and advance manufacturing techniques. These steel S690QL plates are best and ideal for temperature rise work, high pressure and tank fabrication work where accurate & excellent toughness is required for better results.
