SA-210C (25MnG) boiler tube is a kind of pearlitic heat-strength steel. It is a steel grade in the ASMESA-210 standard and a steel in my country's GB5310 standard. It is a carbon-manganese steel small-diameter pipe suitable for the manufacture of boilers and superheaters. The chemical composition of this steel is relatively simple. Except for the higher carbon and manganese content, the other elements are similar to 20G. Therefore, its yield strength is about 20% higher than 20G, while its plasticity and toughness are equivalent to 20G.
The production process of 25MnG structural steel pipe is relatively simple, and its hot and cold processing properties are also very good. This makes it a very practical steel. It can replace 20G, thin the wall thickness, reduce the amount of material, and improve the heat transfer of the boiler. This kind of steel has high economic benefits and practicality during production and use.
