Hastelloy C276 Tube Fittings

Hastelloy Compression Fitting manufacturer and exporter

Like many nickel based alloys, the Hastelloy Tube Fittings are renowned for their corrosion resistance properties. Alloy C22 Compression Fittings tends to exhibit an outstanding immunity to all manner of pitting and cracking. What’s more, is that the Alloy C276 Instrumentation Fittings are highly resistant to oxidation. Hence, the UNS N10276 Instrument Fittings regularly prove to be the right fit for applications that have oxidizing agents.

By adding molybdenum and chromium to its alloy, the Hastelloy Alloy Compression Fittings gains many other important properties as well. For instance, the C22 Hastelloy Tube Adapter Fittings becomes tougher and has enhanced tensile strength. Moreover, the high content of nickel in the alloy is why the C276 Hastelloy Tube Clamp Fittings is able to withstand high temperatures. Properties such as ductility, formability and malleability are inherent to the alloy, therefore producing the Hastelloy C22 Air Tube Fittings is relatively easy. The Hastelloy Push To Connect Fittings also has a high resistance to uniform attack. Another property which makes the Hastelloy C Compression Fittings a worthy alloy is its weldability. A major application of the Hastelloy C276 Tube Fittings is in those settings where the fittings have been exposed to flue gas or flue gas desulfurization plants.

Os-Lok is your superior alternative to Swagelok fittings & Parker A-lok.  Similar to Parker Instrumentation fittings, Os-Lok Hastelloy C276 Compression Fittings work reliably on both seamless and welded-redrawn, fully annealed SA 213 TP304, SA 213 TP316 and SA 213 TP316L Tubing.
