The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the S690QL1 steel mechanical properties steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the S690QL1 steel mechanical properties steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate S690QL1 steel mechanical properties provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.
Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between S690QL1 steel mechanical properties, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company!
