S890QL properties main useage

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and S890QL properties general weldments that do not need heat treatment.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of S890QL properties steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main S890QL properties production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Ultrasonic flaw detection emits ultrasonic waves to the S890QL properties steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the S890QL properties steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, S890QL properties has good atmosphere corrosion resistance.
