Seamless steel tubes for high-pressure boilers are mainly used in pipes, headers, economizers, superheaters and heat exchangers of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. The main grades of seamless steel tubes for high pressure boilers are 15CrMoG, 12CR2MOG, 12Cr1MoV, sa573 gr 70 high strength carbon steel, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.

sa573 gr 70 high strength carbon steel, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. sa573 gr 70 high strength carbon steel, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. sa573 gr 70 high strength carbon steel, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

After adding a small amount of niobium, vanadium and titanium to sa573 gr 70 high strength carbon steel etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

sa573 gr 70 high strength carbon steel, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.
