Offer Ability:5 000MT/Per Month GB/T 1591 Q390C hot rolled high strength steel plates
For GB/T 1591 Q390C hot rolled high strength steel plates, the steel grade Q390C is composed of three parts. Among them, Q represents the steel yield strength "Qu" Chinese phonetic alphabet first letter; 390 is yield strength value, unit MPa; C is quality grade, which is classified into grades B/C/ D/E.
GB/T 1591 Q390C hot rolled high strength steel plates enjoy good comprehensive mechanical properties, good welding performance, cold and hot processing performance and corrosion resistance, as well as good low temperature toughness.
GB/T 1591 Q390C hot rolled high strength steel plates chemical composition:
| Grade | C % | Si % | Mn | P % | S % |
| Q390C | ≤ 0.20 | ≤ 0.55 | 1.00-1.60 | ≤ 0.035 | ≤ 0.035 |
GB/T 1591 Q390C hot rolled high strength steel plates mechanical property:
| Grade | Thickness | Yield Strength (Mpa) | Tensile Strength | Elongation(%) | Impact Energy | |
| (mm) | (MPa) | Min | ||||
| Q390C | ≤16 | 390 | 490-650 | 20 | 0 | 34 |
| >16-35 | 370 | 490-650 | 20 | 0 | 34 | |
| >35 | 350 | 490-650 | 20 | 0 | 34 | |
| The min impact energy is longitudinal energy | ||||||
When needs the thickness direction property of the GB/T 1591 Q390C hot rolled high strength steel plates, the symbol of the performance level representing the thickness direction (Z direction) is added after the Q390C grade. Q390C steel plates are mainly used in ships, boilers, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other welded structures with higher loads.
