Performance index of S690 steel equivalent grades steel sheet/coil

What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. S690 steel equivalent grades, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. S690 steel equivalent grades, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.

S690 steel equivalent grades, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.
