Product Introduction
Titanium alloy screws represent the pinnacle of modern fastener technology, combining an exceptional strength-to-weight ratio with outstanding corrosion resistance. These premium fasteners are engineered for applications where reliability, durability, and weight savings are critical. Unlike conventional steel screws, titanium alloy variants maintain their integrity in harsh environments, including marine, chemical, and aerospace conditions.

2. Hardness (Maximum Limit)
Brinell Hardness (HBW): ≤290
Rockwell Hardness (HRC): ≤32
3. Charpy V-notch Impact Toughness (Longitudinal Specimen)
At 20°C (room temp): Min average impact energy ≥100 J
At -10°C: ≥100 J
At -50°C: Min average 45 J, single specimen ≥35 JExcellent low-temperature toughness, no brittle fracture under cryogenic working conditions
4. Elevated Temperature Yield & Tensile Strength (Reference)
| Temperature | 0.2% Yield Strength | Tensile Strength |
|---|---|---|
| 212°F (100°C) | 65 ksi / 448 MPa | 101 ksi / 696 MPa |
| 392°F (200°C) | 58 ksi / 400 MPa | 95 ksi / 655 MPa |
| 482°F (250°C) | 55 ksi / 379 MPa | 94 ksi / 648 MPa |
Note: Long-term service above 280°C will precipitate brittle sigma phase, sharply reduce impact toughness and corrosion resistance
5. Key Mechanical Characteristics for Product
Ultra-high strengthYield strength is more than twice that of 316L austenitic stainless steel. Thinner wall pipes can be adopted under the same pressure requirement to save material cost.
Balanced strength & ductilitySufficient elongation supports cold forming, including cold bending, U-tube processing and flaring operations.
Outstanding fatigue & erosion resistanceResist cyclic fluid impact and corrosion fatigue, ideal for high-pressure circulating pipeline & heat exchanger service.
Work hardening during cold processingHardness and yield strength rise sharply after cold drawing / cold bending. Stress relief or full solution heat treatment is recommended for anti-corrosion critical projects to avoid chloride stress corrosion cracking (SCC).
Welded joint performanceWeld metal with ER2594 filler maintains qualified mechanical properties; interpass temperature must be controlled below 150°C to prevent toughness drop.

Frequently Asked Questions
What is S32750 Stainless Steel Pipe?
+
-
S32750 is a super duplex stainless steel pipe with approximately 25% chromium, 7% nickel, 4% molybdenum, and added nitrogen. It offers excellent corrosion resistance and high mechanical strength for demanding industrial applications.
What is the difference between S32750 and 2205 Duplex?
+
-
S32750 has a higher chromium, molybdenum, and nitrogen content than 2205, providing a higher PREN value (>40), better pitting resistance, and improved performance in seawater and chloride-rich environments.
Is S32750 suitable for seawater applications?
+
-
Yes. S32750 is widely used in seawater cooling systems, desalination plants, offshore platforms, and marine piping due to its excellent resistance to chloride corrosion and stress corrosion cracking
Can you supply seamless and welded pipes?
+
-
Yes. We manufacture both seamless and welded S32750 stainless steel pipes in standard and custom dimensions.
Do you provide EN 10204 3.1 certificates?
+
-
Yes. Every shipment can be supplied with EN 10204 3.1 Mill Test Certificates, with third-party inspection reports available upon request
