Welding q345r steel steel yield strength

The common uses of q345r steel, boiler and pressure vessel steel plate are as follows. First, make boilers and pressure vessels. Boiler and pressure vessel steel plate not only has a certain strength, but also has a certain ability to withstand impact. The boiler and pressure vessel steel plate should be resistant to abrasion and high temperature. Second, the boiler and pressure vessel steel plate is used to make spherical tank, oil gas tank, liquefied gas tank and other tanks. The boiler and pressure vessel steel plate should have the characteristics of corrosion resistance and pressure resistance.
