F. and 25,00 psi for 64 days, Alloy X had a nitride case less than one-fourth as thick as the closest competitive material without intergranular attack.

Hastelloy B3 bolts are also known as alloy B-3 bolts and can be found under UNS N10675. This alloy is extremely resistant to pure hydrobromic, sulfuric and hydrochloric acids. Many industries, including the chemical industry, consider the alloy easy to machine, and its ductility allows machinists to easily form and even weld.

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 B3 Socket Weld Flanges is dual-certified to meet both SS 316 and SS 316L.

Pipe bending allows systems to minimize pressure changes while still routing materials through complex piping systems.

HASTELLOY X pipe bend is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. All of the product forms are excellent in terms of forming and welding.

Nickel Alloy C-276 and Hastelloy C-276 can be welded by all common welding methods (oxyacetylene is not recommended).

Hastelloy C276 grade round bars also have good corrosion resistance in seawater and brine solutions. They are also known for their resistance to localized corrosion such as stress-related corrosion cracking and pitting.

Hastelloy C276 boards can be easily welded using the most traditional processes. In general, 2.4819 Hastelloy C276 Coil does not require post weld heat treatment. Brushing these boards with stainless steel wire after the welding operation usually removes the hot color and likewise creates surface areas that do not require additional pickling.

HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications.

Plates are designed by continuous rolling and casting or, in most instances, steel is processed into a bullet then hot rolled to be shaped in its final plate thickness. Akin to steel plates, rolled ring forgings are forged in the same process ¨C it differs only in terms of rolling directions.
For cups having comparative large thickness and plates having
complicated cross-sectional shapes, plate forging is more useful than billet forging due to due to
comparatively small change in shape.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900¡ãF. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers.

Hastelloy B2 pipe bend provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media.

Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Alloy X pipe bend is known for its excellent high temperature strength withstanding up to 2200¡ãF. The alloy can also be easily fabricated with forming and welding characteristics by both manual and automatic methods.

This nickel steel alloy can be used in the as-welded condition because it resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone.

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.

Alloy B-2 has poor corrosion resistance to oxidizing environments, therefore, it is not recommended for use in oxidizing media or in the presence of iron or copper salts, which may cause rapid premature corrosion failure.

Hastelloy B2 is a nickel base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures.

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.

Hastelloy C276 clad plate is a chromium, nickel, iron, and molybdenum grade that is solid-solution strengthened.

Alloy B (UNS N10001) was developed to resist hydrochloric acid. Hastelloy B2 has replaced it. Alloy B3 (UNS N10675) is a newer variant with higher thermal stability. These alloy B2 bolts are a wrought nickel molybdenum alloy that can be used in the as-welded condition. It is highly resistant to hydrochloric acid of all concentrations and temperatures. Known as UNS N10665 bolts, these bolts are also resistant to stress corrosion cracking and pitting.

Hastelloy C276 alloy hollow rods tend to exhibit excellent resistance to localized corrosion and oxidizing media as well as reducing media.

Hastelloy C-276 alloy can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can be successfully deep-drawn, spun, press formed or punched.

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

Pipe bending methods will vary based upon the metals used.

Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments.Alloy C-276 is one of the most universally corrosion resistant alloys available today.
