Super Duplex Stainless Steel Dss Sa182 F60 F61 F65 2507 2205 Hexagon Torx Slotted Cross Recess Pan Head Metal Screw Din Iso

Super Duplex Stainless Steel Dss Sa182 F60 F61 F65 2507 2205 Hexagon Torx Slotted Cross Recess Pan Head Metal Screw Din Iso 

This pan head screw is manufactured from Super Duplex Stainless Steel grades including SA182 F60 (2205), F61, F65, and 2507. These alloys offer extremely high strength (yield strength over twice that of 316) and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (PREN >40). Drive options include hexagon head, Torx, slotted, and cross recess – accommodating global assembly preferences. Conforms to DIN and ISO standards. The pan head provides a large bearing surface. This material is the ideal choice for extreme corrosive environments such as marine engineering, chemical plants, desalination, and offshore oil and gas platforms. Grade 2507 offers the highest level of corrosion resistance and strength.

• Offshore oil and gas platform equipment – 2507 super duplex resists seawater and H₂S.

• Desalination plant high-pressure pipe flanges – F61 resists high chloride levels.

• Chemical reactor manway covers – 2205 (F60) resists acids and chlorides.

• Coastal bridge fasteners – super duplex outlasts 316 significantly.

• Flue gas desulfurisation (FGD) units – F65 resists acidic slurry corrosion.

• Super Duplex material – PREN >40, far superior to 316 in chloride resistance.

• Extremely high strength – yield strength ≥550 MPa, double that of 316.

• Four drive options – hex, Torx, slotted, cross – globally versatile.

• Pan head design – large bearing surface suitable for thin sheets or composites.

• Extreme environment ready – offshore, chemical, desalination, FGD.
