Boiler steel (20g) is a general term, which includes boiler steel pipe and boiler steel plate. Steel pipe is mainly used for heating surface, and steel plate is mainly used for the production of boiler drum. 20# steel contains "high-quality steel calm" (Class A) and "boiling steel" two kinds of steel mechanical properties are basically the same, the difference is that the oxygen content of boiling steel is greater than the calm steel, boiling steel is mainly used for the production of section steel, such as Angle steel, I-steel, etc. The killed steel can be made into ordinary pressure vessels and steel tubes.
