Product Details

Product Introduction: ASTM A213 T9 Chromium-Molybdenum Alloy Seamless Heat Exchanger Tubes

1. Material & Chemical Composition

ASTM A213 T9 tubes are crafted from a chromium-molybdenum (Cr-Mo) alloy steel, engineered for exceptional heat resistance and structural stability in high-temperature heat exchange systems. Their chemical composition adheres strictly to ASTM standards:

Element	Content Range	Function
Carbon (C)	0.15-0.25%	Enhances high-temperature strength
Chromium (Cr)	8.00-10.00%	Improves oxidation and corrosion resistance
Molybdenum (Mo)	0.90-1.10%	Boosts creep resistance at elevated temps
Manganese (Mn)	≤0.60%	Aids in grain refinement
Silicon (Si)	≤0.50%	Enhances oxidation resistance
Phosphorus (P)	≤0.025%	Minimized to prevent brittleness
Sulfur (S)	≤0.025%	Controlled to reduce corrosion risk

2. Mechanical Properties

Designed for extreme thermal stress, these tubes deliver superior mechanical performance in high-heat environments:

Property	Value	Advantage in Applications
Tensile Strength	≥515 MPa	Resists rupture under pressure
Yield Strength	≥205 MPa	Maintains integrity under load
Elongation (in 50mm)	≥30%	Accommodates thermal expansion
Maximum Operating Temp	650°C (1202°F)	Ideal for high-temperature heat exchangers

3. Equivalent Materials & Standards

For global project compatibility, ASTM A213 T9 aligns with these international equivalents:

Standard	Material Grade	Region
ASTM A213 T9	Cr-Mo Alloy Seamless	USA
DIN 17175	10CrMo9-10	Europe
JIS G3462	STBA 26	Japan
GB 5310	12Cr1MoVG	China

4. Processing Technology

Our ASTM A213 T9 tubes undergo precision manufacturing to ensure reliability:

Seamless Production: Hot-rolled from alloy billets, ensuring uniform wall thickness and no weak seams.
Solution Annealing: Heat-treated at 900-980°C to optimize grain structure and enhance creep resistance.
Cold Finishing: Optional cold drawing for tight dimensional tolerances (±0.3% on diameter).
Quality Validation: 100% ultrasonic testing, eddy current inspection, and hydrostatic pressure testing (at 30% above design pressure).

5. Application Scenarios

Perfect for high-temperature heat exchange systems in:

Petrochemical Industry: Refinery heat exchangers, reformers, and hydrocrackers.
Power Generation: Boiler superheaters, reheaters, and turbine cooling systems.
Chemical Processing: High-temperature reactors and process heat exchangers.

6. Product Advantages

Extreme Temp Resistance: Maintains strength at up to 650°C, outperforming standard carbon steel tubes.
Creep Resistance: Cr-Mo alloy minimizes deformation under long-term high-temperature stress.
Corrosion Resistance: Chromium content resists oxidation and chemical attack in harsh environments.
Seamless Reliability: Eliminates leak risks, critical for high-pressure heat exchange applications.

7. FAQ

Q1: Can these tubes be customized for specific lengths or wall thicknesses?
A: Yes, we offer diameters from 12mm to 168mm, wall thicknesses from 1.5mm to 12mm, and cut-to-length options (1-12m) with precision end finishes.

Q2: What certifications are provided with each order?
A: All tubes include ASTM A213 certification, mill test reports (MTR), and optional ASME BPVC Section I/II stamps for pressure vessel applications.

Q3: How do these compare to carbon steel tubes in high-heat applications?
A: ASTM A213 T9 offers 30% higher creep resistance and 50% better oxidation resistance than carbon steel, extending service life in temperatures above 450°C.
