General attributes:
UNS S32760 / F55 / 1.4501 is a super duplex stainless steel. Contains 0.75% tungsten and copper, 25% chromium (austenite / ferrite) steel. The alloy's PREn (pitting equivalent) number is> 40.0, which ensures high pitting resistance. UNS S32760 / F55 / 1.4501 has high mechanical strength, good ductility, and corrosion resistance to the marine environment at both atmospheric and sub-zero temperatures. Good resistance to abrasion, corrosion and cavitation and can also be used in the working environment of acid media.
Mainly used in oil and gas and offshore applications, typically in pressure vessels, choke valves, Christmas trees, flanges and piping systems.
Chemical composition of S32760 / F55 / 1.4501 Super Duplex Seamless Pipe:
| Grade: S32760 | Standard: UNS | W: 0.5-1.0 | Others: Cr + 3.3Mo + 16N≥40 | |
| C: ≤0.03 | Si: ≤1.0 | Mn: ≤1.0 | P: ≤0.03 | S: ≤0.01 |
| Cr: 24-26 | Ni: 6.0-8.0 | Mo: 3.0-4.0 | N: 0.2-0.3 | Co: 0.5-1.0 |
Material description: The main chemical components Cr, Ni, Mo, N, etc. have a certain degree of improvement over 2205, 2304, 2101. It has better performance in terms of oxidation resistance, acid corrosion resistance, seawater corrosion resistance, chloride ion corrosion, etc. It also has good strength.
