This grade still provides a higher yield strength than other super duplex grades, whilst its higher copper content of 2.0% ensures excellent resistance to corrosion from a range of acids including sulphuric acid, nitric acid and phosphoric acid.
Improvements in the 1950s included the development of grades that used nitrogen to reduce the likelihood of cracking during casting and welding. Second generation duplex These

The corrosion resistance is comparable to the standard austenitic steel grades like 304/304L (4301/4307) and 316/316L (4401/4404) respectively high alloyed ferritics like 444 (4521). Super duplex stainless steel grades. Our duplex steel
Langley Alloys specialise in the distribution of duplex and super duplex stainless steels. We invented the very first super duplex stainless steel, Ferralium 255 (F61, UNS S32550, 1.4507), more than 50 years ago. Since

- Are super duplex grades suitable for high or low temperature service?
- Like other duplex (ferritic/austenitic) grades the super duplex grades are not suitable for high or low-temperature service. UNS S32750 is not recommended for temperatures below -50°C or above +300°C, because of reduced toughness outside this range. High mechanical strength.
- Which is better SS316 or SDSS?
- SDSS has higher yield strength, which allows for the design of thinner and lighter components, and better resistance to pitting, crevice corrosion, and stress corrosion cracking. However, SS316 may be preferred in less demanding environments due to its lower cost and easier machinability. 2. Is 2205 Duplex or Super Duplex?
- What is Grade 2205 used for?
- Pulp and paper industry: Grade 2205 is used in pulp and paper production equipment, where corrosion resistance is crucial. This super duplex grade has very high pitting and crevice corrosion resistance thanks to its high molybdenum and chromium content.
- What is a super duplex SDSS?
- Notable Super-Duplex grades include 2507, Zeron 100, UR 52N+, and DP-3W. The chemical composition of SDSS is carefully balanced to optimize its mechanical and corrosion-resistant properties. The typical composition includes: Other elements: Iron (Fe), Manganese (Mn), Silicon (Si), and minor amounts of elements like Copper (Cu).
