Product Description
T11 Steel/ DIN 1.6580 Overview:
T11 steel, also known as ASTM A213 T11, is a low alloy steel commonly used in high-temperature service applications such as boiler tubes and heat exchangers. It offers good mechanical properties and high temperature strength, making it suitable for demanding industrial environments.
Chemical Composition:
Properties:
1.High Temperature Strength: T11 steel exhibits excellent strength and creep resistance at elevated temperatures, making it suitable for use in high-temperature service environments.
2.Good Mechanical Properties: T11 steel offers good tensile and yield strength, along with adequate toughness, ensuring reliable performance in demanding applications.
3.Excellent Weldability: T11 steel is easily weldable using conventional welding techniques, allowing for the fabrication of complex structures and assemblies.
4.Corrosion Resistance: With its alloying elements, T11 steel provides good resistance to oxidation and corrosion, enhancing its durability and longevity in corrosive environments.
5.Dimensional Stability: T11 steel maintains dimensional stability during heat treatment and service, minimizing distortion and ensuring dimensional accuracy in finished components.
6.Versatile Applications: T11 steel is commonly used in the construction of boiler tubes, heat exchangers, and superheaters for power generation, petrochemical, and refining industries.
Heat Treatment:
T11 steel is typically supplied in the normalized, annealed, or quenched and tempered condition, depending on the specific requirements of the application. Heat treatment processes may include:
Normalizing: Heating to a temperature of 870-920°C, followed by air cooling to achieve uniform grain structure and improve machinability.
Annealing: Heating to a temperature of 760-815°C, followed by slow cooling in the furnace to relieve internal stresses and refine the microstructure.
Quenching and Tempering: Heating to a temperature of 960-1020°C, followed by rapid cooling in water or oil and tempering at 710-775°C to achieve the desired combination of hardness and toughness.
Surface Treatment:
Surface treatments such as shot blasting or pickling may be applied to T11 steel to remove surface impurities and improve surface finish and cleanliness.
Quality Assurance:
T11 steel is produced and tested according to international standards such as ASTM A213/A213M or equivalent, ensuring consistent quality, mechanical properties, and performance in various applications.
Environmental Considerations:
In the production and processing of T11 steel, environmental considerations such as energy efficiency, waste management, and emissions control should be addressed to minimize environmental impact and promote sustainability in the industry.
