Introduction EN 10025-6 S690QL high strength steel or EN 10025-6 S690QL high strength steel materail

Steel plate EN 10025-6 S690QL high strength steel cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick EN 10025-6 S690QL high strength steel steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

The difference of chemical composition between EN 10025-6 S690QL high strength steel, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between EN 10025-6 S690QL high strength steel, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has EN 10025-6 S690QL high strength steel strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and EN 10025-6 S690QL high strength steel pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate EN 10025-6 S690QL high strength steel shaped parts.
