Q490RW quenched and tempered container plate, Q490RW large line energy welded steel plate, Q490RW st

Q490RW large line energy welded steel plate, Q490RW is a quenched and tempered high-strength steel plate for pressure equipment, and it is a steel plate for large oil storage tanks.

Q490RW steel plate rolling: cxysteel@126.com

The grade of Q490RW steel is composed of the Chinese pinyin letter "Q" representing the yield strength "yield", the specified small yield strength value, the Chinese pinyin initial letter "R" of the pressure vessel "capacity" or the Chinese pinyin initial letter "DR" of the low temperature pressure vessel "low capacity", and the temperature grade "L". For the steel required for large-wire energy welding, the first letter "W" of the English word "Weld" representing the word "welding" of large-wire energy welding is added to the grade specified above, such as: Q490RW

Q490RW material features

Q490RW steel plate is a high-strength low-alloy structural steel, where Q represents the yield strength of this steel, 490 indicates the yield strength value, R indicates that this steel is hot-rolled steel, and W indicates that this steel is a wide steel strip. Q490RW steel plate has the following characteristics:

1. High strength: The yield strength of Q490RW steel plate is as high as 490MPa, and the tensile strength is as high as 630MPa, which has high strength and good bearing capacity.

2. Good toughness: The toughness index of Q490RW steel plate, including section shrinkage, impact toughness, etc., is better than that of ordinary carbon structural steel, so that the steel plate has higher safety when bearing shock and vibration loads.

3. Wear resistance: Q490RW steel plate contains high alloying elements, which makes it have good wear resistance and prolongs the service life of the steel plate.

4. Corrosion resistance: The corrosion resistance of Q490RW steel plate is better than that of ordinary steel, so that it can maintain good performance in corrosive environments.
