Duplex Tube Fittings

Duplex Steel UNS S31803 Ferrule Fittings manufacturer in India

The Duplex Tube Fittings are renowned for their dual microstructure phase. The microstructure of DSS Bulkhead Tube Fittings is an equivalent 50 % each austenite and ferrite. Therefore the Duplex Steel Instrument Tube Fittings share characteristics of both steel classes.

For instance, the Super Duplex Steel Imperial Tube Fittings inherit the high tensile strength and corrosion resistance properties from their austenite part. While the Duplex SS Tube Adapter Fittings inherit toughness and hardness characteristic from the ferrite portion. What’s more, is that the SDSS Industrial Tube Fittings have excellent resistance to pitting. In fact, the PREN score of Super Duplex Hose Fittings ranges from 38 to about 45. The lower content of nickel in the alloy for Duplex Stainless Steel Push To Connect Tube Fittings makes it a cost saving solution. Since nickel is a very expensive metal, alloying costs increase. However, the SDSS Hydraulic Fittings do not use a lot of nickel when they are alloyed, thereby becoming a cost efficient alternative.

Os-Lok is your superior alternative to Swagelok fittings & Parker A-lok.  Similar to Parker Instrumentation fittings, Os-Lok DSS Tube Fittings work reliably on both seamless and welded-redrawn, fully annealed SA 213 TP304, SA 213 TP316 and SA 213 TP316L Tubing.
