ASTM A815 UNS S31803 Fittings

ASTM A815 UNS S31803 Fittings

With a mixed microstructure, in an annealed condition, the alloy consists of 40-50% ferrite, with austenite. The ASTM A815 UNS S31803 Fittings gets its corrosion resistance properties from the austenite portion, while its strength and hardness are inherited from the ferrite portion of its microstructure.

The cutting speed of Duplex Steel S31803 Pipe Fittings is about 20% lower than a conventional grade like 304. This is because its high strength makes it less machinable.

There are several types of elbows available based on the radius type and angle. The most common angles for elbow fittings are 45, 90 and 180 degrees. However, they can be customised, depending on the need of the application. The other types of elbows are – short and long radius, socket weld, threaded, buttweld and reducer elbow.

One of the best features that make the WNR 1.4462 Tee, better than austenitic alloys is its resistance to stress corrosion cracking. In the presence of chloride ions, the fittings exhibit resistance without becoming susceptible to either pitting or crevice corrosion. They work well in marine environments because they are extremely resilient to the presence of salt in seawater.

Work hardening this alloy using thermal processes is not possible. However, it can be annealed by solution treating between a temperature range of 1020 – 1100°C.

The nature of its dual microstructure makes it possible for the UNS S31803 Fittings to be used at temperatures as high as 300°C. Using it above this temperature range results in the formation of grain boundary precipitates.
