S690QL1 material equivalent Comparison

Many people will mix strip steel and steel plate together, which can usually be distinguished from the following points. First of all, the thickness of the steel plate is much thicker, and the thinner the strip steel is required, the better. Secondly, in appearance, the steel strip can be crimped and the steel plate is too thick to bend, even if it is bent, it is difficult to recover, because it is easy to break if it is bent too much. Thirdly, the strength of S690QL1 material equivalent, steel plate is higher than that of strip steel. The steel plate is suitable for construction engineering, while strip steel is only suitable for processing into hardware products.

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 company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

S690QL1 material equivalent controlled rolling is that, on the basis of adjusting the chemical composition of S690QL1 material equivalent, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S690QL1 material equivalent.
