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.
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.
