High-performance 2507 super duplex stainless steel tube with excellent corrosion resistance, high strength, and low thermal expansion. Ideal for seawater and chemical processing. OEM customization available from certified Chinese factory.
At Jiuguang Metal, we specialize in manufacturing high-performance 2507 stainless steel tubes, also known as UNS S32750 super duplex stainless steel. With 25% chromium, 4% molybdenum, and 7% nickel, this alloy delivers exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, even in aggressive environments.
With its high tensile strength, excellent thermal conductivityund low thermal expansion, 2507 is widely used in chemical processing plants, petrochemical systems, offshore platformsund seawater desalination facilities. Our tubes are manufactured to precise tolerances and comply with global standards including ASTM, AISI, EN, DIN, and JIS, with full OEM customization supported.

2507 contains a higher level of chromium, molybdenum, and nitrogen than standard duplex grades, offering superior corrosion resistance and mechanical strength in harsh environments.
It’s used in seawater equipment, heat exchangers, pressure vessels, desalination plants, and chemical/petrochemical industries due to its extreme corrosion resistance and durability.
Yes. We offer complete OEM customization, including non-standard wall thicknesses, shapes, and pre-cut lengths based on your project drawings.
Yes. We manufacture both types to suit different pressure and cost requirements.
Each order is delivered with Mill Test Certificates (EN10204 3.1/3.2). We also support SGS, TUV, BV, ABS, and LR third-party inspections upon request.
While 2507 performs excellently in corrosive environments, it’s generally recommended for use in temperatures below 600°F (316°C) to avoid embrittlement.
