Product Description

ASTM A790 S32750 Super Duplex Seamless Boiler Tube – High Corrosion & Pressure Resistance

1. Product Overview

ASTM A790 S32750 Super Duplex Seamless Boiler Tubes are engineered for extreme environments in boilers, heat exchangers, and offshore platforms. Manufactured under ASTM A790/ASME SA790 standards, these tubes combine exceptional corrosion resistance with high mechanical strength, ideal for chloride-rich and high-pressure applications.

2. Material & Chemical Composition

Material: Super Duplex Stainless Steel (UNS S32750, equivalent to 2507).
Key Chemical Properties:

Element	Content (%)
Chromium (Cr)	24.0–26.0
Nickel (Ni)	6.0–8.0
Molybdenum (Mo)	3.0–5.0
Nitrogen (N)	0.24–0.32
Carbon (C)	≤0.030

3. Mechanical Properties

Property	Value
Tensile Strength	≥800 MPa
Yield Strength	≥550 MPa
Elongation	≥15%
Hardness	≤310 HB

4. Key Features & Advantages

Superior Corrosion Resistance: Resists pitting, crevice, and stress corrosion cracking (PREN >40).
High-Temperature Performance: Suitable for -50°C to 300°C environments.
Seamless Design: No welds, ensuring leak-proof performance under high pressure.
Certified Quality: Complies with ASTM A790, ASME SA790, and EN 10216-5.

5. Applications

Oil & Gas: Subsea pipelines, FPSO systems.
Chemical Processing: Acid transport, flue gas desulfurization (FGD).
Power Plants: High-pressure steam boilers.

6. FAQ

Q: How does S32750 compare to standard duplex grades like 2205?
A: S32750 has higher Cr, Mo, and N content, offering 50% greater strength and better chloride resistance.

Q: Can you supply custom sizes?
A: Yes! We support OD: 10–1200mm, thickness: 1–50mm, and lengths up to 18m.
