ASTM A213 T9 Alloy Steel Heat Exchanger Tube for Petrochemical and Power Plant

Product Overview

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.
