As an austenitic microstructured superalloy, Hastelloy C22 is considered to be one of the most versatile metals around for a number of reasons. Firstly, the Hastelloy C22 Round Bar has excellent resistance to a variety of corrosion forms, including crevice corrosion, and pitting corrosion. Secondly, the alloy has exceptional resistance to stress corrosion cracking or SCC, so the ASTM B574 UNS N06022 Bar is ideal for use in flue gas desulfurization plants.

In chemical processing industries, particularly those with fluctuating or upset conditions, the C22 Hastelloy Square Bar exhibits excellent resistance in both reductive and oxidative media. Due to its outstanding resistance to both reductive and oxidative media, the alloy is widely regarded as being an excellent choice for chemical processing industries. In industries where conventional stainless steels tend to corrode due to oxidative compounds such as acetic anhydride or ferric acid, the DIN 2.4602 Flat Bar does not corrode.

There are relatively small amounts of carbon in Hastelloy C22 Rod, which makes it extremely weldable, while it also exhibits excellent resistance to cracks and failure caused by intergranular corrosion, which will result in high-quality welds. It has therefore been determined that Alloy C22 Hex Bar is considered to have good weldability because it shows resistance to grain boundary precipitates developing in the heat-affected zone or the HAZ at the welds.

A superalloy, Hastelloy is one of the world's most versatile alloys, and this Hastelloy C22 Round Bar is made with a Hastelloy c22 composition chemical that is 22 % chromium, 14 % molybdenum, and 3% tungsten. This steel tube is designed to offer excellent mechanical properties, and it has a tensile strength of 690 MPa and a yield strength of 310 MPa. Hastelloy C22 is an extremely corrosion-resistant alloy that offers excellent mechanical properties. ASTM B574 Flat Bars of Hastelloy C22 is designed to offer good mechanical properties.

These bars are capable of elongating by 45%, and they retain excellent workability even when subjected to extreme pressures and temperatures. Hastelloy B574 Hollow Bars are used in applications that require them to function at extreme temperatures and pressure. The ASTM B574 Hastelloy C22 Rod is capable of resisting acids, oxidants, and reducing agents. Approximately 8.69 g/cm3 is the density of the Hastelloy Alloy C22 Round Rod, which is used to provide structural support. As well as having excellent strength, these rods have excellent electrical conductivity. They are suitable for temperatures up to 1250 degrees Fahrenheit. As a manufacturer and supplier of Alloy C22 Round Bars, we are known for the quality of our products, which are available at reasonable rates. Hastelloy C22 Bars are widely used in the chemical industry, paper, and pulp production, pollution control, marine applications, and waste treatment systems.

As a connector between the center and the bar, ASTM B574 Alloy N06022 Hex Bars are widely used in pressure valves to prevent excess pressure. All ASTM standards are followed when manufacturing the Hastelloy C22 N06022 Hexagon Bars, which can be found in sizes from 6mm to 105mm. These bars are manufactured according to all ASTM standards. Upon being processed at high temperatures, the Hastelloy C-22 Hot Rolled Bar 2.4602 is produced. They are made especially for machines and systems that require accurate sizes. In addition to being dimensionally accurate, these bars exhibit good strength and are highly ductile, with a high degree of surface finish. It is very easy to work with and extremely strong because of these enhanced c22 steel properties. In addition to its corrosion and oxidation resistance, the Hastelloy UNS N06022 Cold Finished Bar can be easily annealed and pickled due to its ductile properties. Enhanced strength and outstanding mechanical properties make Hastelloy C22 Alloy Round Bars ideal for forging. A Hastelloy C-22 Forged Bar has a thickness that ranges from 3mm to 12mm and has excellent fatigue and impact resistance. In addition to being easy to maintain, these Alloy C22 Hastelloy Bright Bars possess a smooth and shiny finish. These bars are available in various shapes. This Hastelloy C22 UNS N06022 Polished Bar has precise shapes and good tolerances. It is available in different types of finishes in addition to being made from Hastelloy C22.

Resistance To Corrosion When Welded

As an extremely versatile Nickel-Chromium-Molybdenum alloy, Hastelloy C-22 is one of the best Ni-Cr-Mo alloys that have been developed today and offers better corrosion resistance than any other Ni-Cr-Mo alloys, including Hastelloy C-276, C-4, and A625. In addition to its outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, it also has excellent resistance to other corrosion-related issues. Aqueous media that are oxidizing such as acids with oxidizing agents, wet chlorine, nitric acid, and mixtures of oxidizing acids and chlorine ions have been found to be very resistant to it. The Hastelloy C-22 stainless steel exhibits outstanding resistance to both reducing and oxidizing media, and because of its versatility, it is ideally suited for use in multipurpose plants and in situations where 'upset' conditions are likely to occur.

Its exceptional resistance to a wide range of chemical process environments has been noted in the history of Hastelloy C-22. Strong oxidizers such as ferric and cupric chlorides, hot and toxic media, chlorine, formic and acetic acids, acetic anhydride, seawater, and brine solutions can all be used to process Hastelloy C-22.

In the as-welded condition, Hastelloy C-22 is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, which makes it suitable for most chemical process applications, even when it is welded.


A wide range of fabrication techniques can be used to fabricate Hastelloy C-22, including welding, rolling, forming, forging, hot-upsetting, compression, and impact extrusion, though the alloy may tend to harden on deep drawing.

Prior to final fabrication or installation, parts that have been hot formed or severely cold formed should be heat treated at 2050°F and rapidly quenched.


The UNS number for Hastelloy C-22 is NO6022. It can be supplied as plates, sheets, strips, bars, tubing, hoses, cylinders, finials, and floats, as well as pipe and tubing. Plates, sheets, strips, bars, flanges, and pipes are covered by ASME specifications SB-574, SB-575, SB-619, SB-622, and SB-626.
