Product Introduction
A214 is a steel grade produced according to American ASTM standards, which belongs to American standard. Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.
Carbon (C): Typically ranges between 0.18% to 0.27%. Carbon provides strength and hardness to the steel.
Manganese (Mn): Usually ranges between 0.27% to 0.93%. Manganese enhances the hardenability, strength, and wear resistance of the steel.
Phosphorus (P): Maximum allowable content is 0.035%. Phosphorus is a residual element that can affect the steel's strength and toughness.
Sulfur (S): Maximum allowable content is 0.035%. Sulfur is another residual element that can impact machinability and weldability.
Silicon (Si): Typically ranges between 0.10% to 0.35%. Silicon enhances the strength and elasticity of the steel and is commonly found in carbon steels.
Electric-Resistance-Welded Construction: ASTM A214 tubes are manufactured using electric-resistance welding (ERW) processes. This method involves passing an electric current through the steel strip or plate, heating it to the point where it forms a bond, creating a seamless weld.
Carbon Steel Composition: The tubes are made from carbon steel, which typically includes elements such as carbon, manganese, phosphorus, sulfur, and silicon. The exact composition is specified to ensure the desired mechanical properties and resistance to corrosion and oxidation.
Specific Size and Dimension Requirements: ASTM A214 specifies the dimensions, tolerances, and lengths of the tubes. These specifications ensure uniformity and compatibility with boiler economizer designs and installation requirements.
Heat Treatment: Depending on the manufacturing process and intended application, ASTM A214 tubes may undergo heat treatment to achieve specific mechanical properties such as hardness and tensile strength.
Application-Specific Design: ASTM A214 tubes are specifically designed for use as economizers in boilers. They are engineered to withstand the high temperatures and pressures associated with exhaust gas heat recovery in boiler systems.
Compliance with Standards: ASTM A214 carbon steel tubes comply with the ASTM A214/A214M standard specifications, ensuring they meet industry standards for quality, performance, and reliability in boiler economizer applications.
