Hastelloy C276 is a nickel-chromium-molybdenum wrought alloy considered to be the most versatile corrosion-resistant alloy known. This alloy is resistant to grain boundary deposits in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. Meanwhile, Hastelloy C276 fasteners are considered to be the most versatile and high-strength fasteners, finding their suitability in many industrial applications. These are nickel-molybdenum-chromium forged alloy fasteners that perform well in a variety of harsh environments. The presence of molybdenum and chromium content makes nickel alloy steel more resistant to crevice and pitting corrosion. Hastelloy c276 bolts are the highest quality bolts in the alloy series. These are corrosion resistant, which is important for the industries in which Hastelloy is best suited.

C-22 is a great alternative when superaustenitic stainless steels (AL-6XN, 904L, and 254 SMO) and duplex stainless steels (2205 and 2507) will not withstand extremely aggressive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy with better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy, like Hastelloy C-276, C-4, and alloy 625.

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

Solved other issues concerning fabricability. Stringent chemistry control along with years of development has resulted in the alloy used today, both in Alloy B2 and Alloy B-3.

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.

Hastelloy G30 Hastelloy alloys exhibit better resistance to commercial phosphoric acid than other nickel or iron based alloys. Its application as an acid evaporator in the fertilizer industry is increasing day by day.
