Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. S690QL material equivalent, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of S690QL material equivalent, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

Vanadium is a weak deoxidizer. Adding vanadium into S690QL material equivalent steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

The executive standard of P235TR1 steel is EN 10216-1. S690QL material equivalent, P235TR1 steel is suitable for manufacturing pipes, vessels, equipment, pipe fittings and steel structures. Chemical composition of P235TR1 steel: C ≤ 0.16, Si ≤ 0.35, Mn ≤ 1.2, P ≤ 0.025, S ≤ 0.02, Cr ≤ 0.30, Mo ≤ 0.06, Ni ≤ 0.30, Cu ≤ 0.30, Nb ≤ 0.01, Ti ≤ 0.04, V ≤ 0.02. Chemical composition of P235TR1 steel: tensile strength 360-500 MPa, yield strength ≥ 235 MPa, elongation ≥ 25%. The main steel pipe grades under EN 10216-1 are P195TR1, P195TR2, P235TR1, P235TR2, P265TR1 and P265TR2.
