The characteristics of A514 Gr.B section steel
Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
The A514 Gr.B section steel processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the A514 Gr.B section steel steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
In today's A514 Gr.B section steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of A514 Gr.B section steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
Rizhao Steel 5#ESP Headless Strip Production Line Project is a key construction project in Shandong Province. It is also the fifth domestic ESP production line introduced by Rizhao Steel and the sixth ESP production line in the world. Its thinnest design is 0.5mm, which is at the world's leading level. The more than 20 important nodes set by the entire project have been basically completed, and the equipment has entered the commissioning stage. It is expected to be put into operation at the end of November.
