The hot rolling method is to heat the EN10025 S690QL for sale 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 EN10025 S690QL for sale rolling process is usually called semi-finished product production, also called blank production.

Oxygen is a harmful element in EN10025 S690QL for sale steel. With the increase of oxygen content, the strength of EN10025 S690QL for sale steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of EN10025 S690QL for sale steel.
