What are the common types of steel used for various components of boilers?
The common steel grades used for manufacturing pressure components of boilers include low-carbon steel, low-alloy structural steel, low-alloy heat-resistant steel, austenitic stainless heat-resistant steel, and martensitic heat-resistant steel, among others.
Steels suitable for manufacturing boilers, including steel for steam drums and steel for boiler tubes. The steel used for steam drums must possess high heat strength, toughness, and structural stability, so as to avoid excessive permanent deformation or rupture under the action of high-pressure warm steam over a long period of time. The steel used for boiler tubes is required to have sufficiently high high-temperature strength, ductile toughness, oxidation resistance and corrosion resistance, structural stability, as well as good workability. Common steels used for steam drums include 12Mn steel, 16Mn steel, 19Mn6 steel, 15MnV steel, 14MnMoV steel, and 13MnNiMoNb steel. Common boiler tube steels include 12CrMo steel, 12Cr1MoV steel, 12MoVWBSiRE steel, 12Cr2MoWVB steel, and 12Cr3MoVSiTiB steel.
What are the common types of steel used for various components of boilers? The common steel grades used for pressure vessels and steel tubes of heating surfaces in pressurized components are mainly low-carbon steel, low-alloy steel, austenitic heat-resistant steel, etc.; for example, 16Mn and 15MnV are commonly used for pressure vessels ； Commonly used steel pipes include 12Cr1MoV, 12Cr2MoWVB, etc.
