C276 is a nickel-molybdenum-chromium superalloy with tungsten added, designed for excellent corrosion resistance in a variety of harsh environments. The high nickel and molybdenum contents make nickel steel alloys particularly resistant to pitting and crevice corrosion in reducing environments, while chromium is resistant to oxidizing media.

Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.

C-276 alloy is normally solution heat-treated at 2050¡ãF (1121¡ãC) and rapid quenched. If possible, parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation.

Process piping systems rarely travel in a straight line from process to process.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Alloy B2 should not be used at temperatures between 1000¡ãF and 1600¡ãF as the alloy forms secondary phases that could decrease the ductility of the material.

The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil and gas, power generation, and the paper industries.

It is used in flue gas desulfurizations systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. C-276 alloy has excellent resistance to pitting and to stress- corrosion cracking.
