What material is the q345r pressure vessel steel plate made of?
q345r is a steel plate, which is a boiler vessel plate. q is the first letter of Chinese Pinyin, 345 means yield strength, and r is the first letter of Chinese Pinyin. Its numbering method is the number of low-alloy high-strength structural steel, using the bending of yield strength value. The word and the first letter of the pinyin of pressure vessel represent.
Its technical and mechanical properties are very stable and it is a low alloy steel. Compared with Q345, Q345R has higher requirements in terms of tensile strength and elongation. Therefore, in order to ensure toughness, the yield strength needs to reach 345MPA.
Q345R is mainly used in boilers and pressure vessels. Its process and mechanical properties are very stable and it is a low alloy steel. Q345R steel is widely used in boilers or petroleum industries. Can be made into liquefied gas tanks or oil cylinders, etc.
Q345R material chemical composition:
| Grade | C % | Si % | Mn % | Cu % | Ni % | Cr% | Mo % | V % | Ti % | Alt % | P % | S % | Nb |
| Q345R | 0.20 | 0.55 | 1.2-1.7 | 0.30 | 0.30 | 0.30 | 0.08 | 0.050 | 0.030 | 0.020 | 0.025 | 0.010 | 0.050 |
