Q580R steel plate is a kind of tempered high-strength steel plate, Q580R is a new grade, the implementation of the new national standard GB/T713.6-2023, can be rolled. Delivery status: quenched and tempered tempered state, tempering temperature not less than 600 ℃, the same grade and Q580DR (-50 ℃ impact).
Q580R Brand name expression
Q - a yield strength "yield" the first letter of the word hanyu pinyin;
580 - the lower limit of the yield strength of the provisions of the lower value, the unit is MPa (MPa);
R - pressure vessel "Rong" of the first letter of the hanyu pinyin.
Q580R steel plate chemical composition should be consistent with the new national standard GB/T713.6-2023 "Pressure Equipment Steel Plate and Strip Part 6: Tempered High Strength Steel". Among them, the main elements include carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and so on. The content and proportion of these elements directly affect the strength, toughness, corrosion resistance of the steel plate.
Q580R steel plate has excellent mechanical properties such as high strength, high toughness, fatigue resistance and impact resistance. Its tensile strength can be up to 690MPa or more, yield strength is about 580MPa, and elongation is more than 16%. After certain heat treatment process, its strength and toughness can be further improved.
