Our quality control department will do inspection for details of the steel materials A588 grade B structural steel plate before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A588 grade B structural steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A588 grade B structural steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of A588 grade B structural steel plate, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of A588 grade B structural steel plate enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the A588 grade B structural steel plate enterprise as the community and belonging of their own interests.
