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.

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.

A bushing is a type of bearing. Generally speaking, “bearings” facilitate movement between two components while reducing friction. Simple in design, a typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.

Hastelloy’s resistance to sulfuric acid makes it a common choice for protection from hydrogen sulfide (H2S), more commonly known as?sour gas.

Hastelloy C276 is known for its excellent corrosion resistance in a variety of corrosive media. It includes chloride ions, sulfur compounds, etc. In addition, this alloy has excellent resistance to crevice corrosion, pitting corrosion and stress corrosion cracking. It helps resist the corrosive effects of wet chlorine, chlorine dioxide and hypochlorite. This product is ideal for seawater applications.

Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X pipe bend excels in both respects due to the formation of a protective, tenacious oxide film.

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.
