Stainless metal structures in swimming swimming pools are identified to be susceptible to SCC. The use of ordinary austenitic stainless steels like 304 and 316 is forbidden on this application. The finest steels to use for this purpose are the excessive nickel austenitic steels such as the 6% Mo grades.

At the opposite finish of the scale, there is a restriction on the low temperature use of duplex stainless steels in comparison with austenitic grades. Unlike austenitic steels duplex steels exhibit a ductile-brittle transition within the impact check. A typical check temperature is minus 46 deg C for offshore oil and gas functions.
LDX 2101 (UNS S32101) is a 21.5% chromium, 5% manganese, 1.5% nickel, 0.forty five% molybdenum lean duplex stainless-steel with corrosion resistance superior to 304L and similar to 316L. LDX 2101 possesses both superior power and greater chloride stress-corrosion cracking resistance than standard 300 collection stainless-steel. They are not quite as easily welded because the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding.
Technique
- A typical test temperature is minus forty six deg C for offshore oil and gas applications.
- Minus eighty deg C is the lowest temperature that’s normally encountered for duplex steels.
- At the other end of the size, there’s a restriction on the low temperature use of duplex stainless steels in comparison with austenitic grades.
- Unlike austenitic steels duplex steels exhibit a ductile-brittle transition within the influence check.

The metallurgy of duplex stainless steels is far more complicated than for austenitic or ferritic steels. This is why 3 day conferences could be devoted simply to duplex! This issue signifies that they are more difficult to supply on the mill and to manufacture.
Like different duplex chrome steel, LDX 2101® offers each superior strength and chloride stress corrosion cracking resistance compared to 300 collection stainless-steel. The use of manganese ensures correct ferrite-austenite phase stability, while allowing a reduction in nickel content material. As a outcome, LDX 2101® is priced competitively with 304/304L and 316/316L stainless-steel. The above-mentioned Lean Duplex, unfortunately, requires a significantly higher strength during cold working than normal austenitic stainless steels.
Whilst duplex stainless steels are thought-about immune to stress corrosion cracking, they aren’t as resistant to this form of assault as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is larger than that for probably the most commonly used grades of stainless steels, i.e. 304 and 316. Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases.
Thermal Properties
However, in some circumstances, duplex steels corresponding to 2205 (1.4462) and the superduplex grades can be thought of. Among wrought stainless steels, the composition of EN 1.4162 stainless steel is notable for holding comparatively excessive amounts of manganese (Mn) and chromium (Cr). Manganese is used to enhance ductility at elevated temperatures. It also permits the next nitrogen content than would otherwise be attainable. Chromium is the defining alloying component of stainless-steel.
