Super Duplex SAF 2507 UNS S32750 Hardness
Super Duplex SAF2507 / UNS S32750 / 1.4410 offers significantly higher strength compared to conventional austenitic and duplex stainless steels. Its dual-phase microstructure, consisting of roughly equal parts of austenite and ferrite, contributes to its superior strength, enabling it to withstand high mechanical loads and stresses. Despite its high strength, SAF 2507 material retains excellent toughness, which is essential for resisting impact loads and preventing brittle fracture in demanding applications.
Mechanical Property For Super Duplex Saf2507 Stainless In Annealed Condition:
1. Sandvik Saf 2507 Super Duplex Tensile Strength: Typically ranges from 800 MPa to 1050 MPa (116,000 psi to 152,000 psi).
2. SAF 2507 S32750 Yield Strength (0.2% Offset): Typically ranges from 550 MPa to 800 MPa (80,000 psi to 116,000 psi).
3. SAF 2507 UNS S32750 Elongation: Typically ranges from 15% to 25%.
4. Super Duplex SAF 2507 Hardness:
- Brinell Hardness (HB): Typically around 270 to 320 HB.
- Rockwell C Hardness (HRC): Typically around 25 to 35 HRC.
- Vickers Hardness (HV): Typically around 250 to 310 HV.
5. Impact Toughness: Generally exhibits good impact toughness at both room temperature and low temperatures, with Charpy V-notch impact values typically exceeding 100 J (74 ft-lbf).
These values can vary slightly depending on factors such as heat treatment, processing conditions, and product form. It's essential to refer to the specific material datasheet or manufacturer's specifications for precise mechanical property values for a particular batch or product form of SAF2507 super duplex stainless steel.
