Hastelloy G-30 is an improved version of nickel-chromium-iron-molybdenum-copper alloy G-3. With higher chromium, added cobalt and tungsten, the G-30 shows superior corrosion resistance over most other nickel and iron based alloys in commercial phosphoric acids as well as complex environments containing highly oxidizing acids. The resistance of the alloy to the formation of grain boundary precipitates in the heat-affected zone makes it suitable for use in most chemical process applications in the as-welded condition.

The Molybdenum of Hastelloy B2 pipe bend is the primary alloying element which provides significant corrosion resistance to reducing environments.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used.

Hastelloy B3 pipe is significantly resistant to corrosion resistance at reducing atmosphere. Hastelloy B2 pipes are having excellent resistance to non-oxidizing acid and sulphuric acid.

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

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 fasteners such as bolts, screws, nuts and threaded rods are ideal for use in a variety of moderately to severely corrosive acid environments. The most common grade of Hastelloy fasteners is Hastelloy C276 (2.4819), which is one of the most versatile corrosion-resistant nickel alloys, surpassing Inconel or Monel. There are also other special grades of Hastelloy fasteners that can address more niche corrosion problems.

Hastelloy B2 Welded Pipes is a wrought nickel-molybdenum alloy that can be used in the ¡®as welded¡¯ condition.

Hastelloy B2 Seamless Pipes is a solid solution strengthened, nickel ¨C molybdenum alloy, typically used in extreme reducing conditions.

Hastelloy B3 Spacer Flanges does not rust, because of the interaction between its alloying elements and the environment.

Hastelloy C276 is an extremely versatile material that has been used in a variety of harsh environments. It exhibits corrosion resistance to chloride-containing media, organic acids, oxidizing media, reducing acids, seawater and brine, and sulphur-containing flue gas. Hastelloy C276 replaces Alloy C (UNS N10002), which has slightly lower chromium and molybdenum contents. The high nickel, molybdenum and tungsten contents make them expensive compared to austenitic stainless steels. It is by far the most popular super alloy.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

La aleacion tambien es resistente a soluciones y compuestos de cloruro, muchos de los cuales son altamente corrosivos. Por ejemplo, los reductores de aleacion de niquel C276 son resistentes no solo a los medios organicos e inorganicos termicamente contaminados, sino tambien a los cloruros ferricos y c¨²pricos, asi como al cloro, el agua de mar y la salmuera.

Hastelloy X fasteners, also known as UNS N06002 fasteners, have excellent corrosion resistance and high temperature strength. It is very resistant to stress corrosion cracking but has excellent ductility when subjected to 16,00 hours of torture at temperatures up to 1,600F. It is also suitable for furnaces, heaters and many high temperature applications because it is weldable, heat treatable and relatively easy to machine. That’s why we think Hastelloy X fasteners basically offer the best of both worlds – corrosion and heat resistance.
