Our ASTM A213 T9 Alloy Steel Heat Exchanger Tube is a premium-grade 9Cr-1Mo (9% Chromium, 1% Molybdenum) ferritic alloy steel tube specifically engineered for high-temperature heat exchanger services in petrochemical plants, power generation facilities, and refinery operations. The cold-drawn manufacturing process ensures precise dimensional tolerances, superior surface finish, and exceptional mechanical properties essential for critical heat transfer applications with operating temperatures reaching up to 595°C (1,100°F).
Key Features & Advantages
Exceptional High-Temperature Performance: The 9Cr-1Mo composition provides outstanding creep resistance and mechanical strength stability under continuous high-temperature service, making it the preferred choice for superheater and reheater tube applications.
Superior Oxidation and Corrosion Resistance: Chromium content of 8.0-10.0% forms a protective oxide layer that effectively resists high-temperature oxidation, sulfidation, and steam corrosion in harsh industrial environments.
U-Bend Fabrication Capability: Available in straight lengths or U-bend configurations with stress-relief heat treatment after bending to eliminate residual stresses, ensuring long-term reliability in shell-and-tube heat exchangers.
Strict Chemical Control: Carbon content limited to 0.15% max, with controlled manganese (0.30-0.60%), phosphorus (≤0.025%), and sulfur (≤0.025%) for optimal weldability and formability.
Verified Mechanical Properties: Tensile strength ≥415 MPa, yield strength ≥205 MPa, elongation ≥30% at room temperature, with full compliance to ASTM A213/ASME SA213 standards.
Application Scenarios
Shell-and-tube heat exchangers in refinery crude oil processing units
Boiler superheaters, reheaters, and economizers in thermal power plants
Steam generators and high-pressure feedwater heaters
Ethylene cracker furnace tubes in petrochemical complexes
Nuclear power plant secondary and auxiliary heat exchange systems
Concentrated Solar Power (CSP) thermal receiver tubes
Company Capabilities
Triple Certified: BV, SGS, ABS certified with full material traceability from mill to delivery
Advanced Testing: 100% eddy current, ultrasonic, and hydrostatic testing with comprehensive chemical and mechanical property analysis
U-Bend Processing: In-house CNC bending with post-bend stress-relief heat treatment and dimensional verification
Annual Capacity: 10,000 tons with MOQ of 1 ton, delivery within 7-10 working days
Flexible Terms: T/T or L/C payment, pricing USD 600-1,500 per ton
Export Packaging: Individual tube protection with end caps, seaworthy wooden cases for U-bend assemblies
