Common Applications for Hastelloy C276 Bars

What Are Hastelloy C276 Bars?

Chemical process equipment, pollution control units, nuclear fuel processing systems, pharmaceutical industry equipment, paper industry equipment, off-shore oil rigs, and power generation components commonly use Hastelloy C276 Bars. Its superior performance in highly corrosive environments makes it an ideal choice for these applications. You can use it as structural components and protective surface coatings on other materials such as steel or stainless steel.

Hastelloy C276 is a nickel-molybdenum-chromium alloy with excellent corrosion resistance in numerous media. It has good weldability, formability, and machinability. Due to its high chromium content, the alloy is particularly resistant to pitting, stress corrosion cracking, and localized attacks such as crevice corrosion. This makes it ideal for environments with high chloride concentrations or other corrosive elements.

Properties of Hastelloy C276 Bars

The alloy has several desirable properties, making it popular in many industrial settings. These include excellent tensile strength (up to 95ksi), good flexibility (up to 40%), excellent oxidation resistance (up to 1200°F), and excellent weldability (with proper technique). The nonmagnetic and nonhardenable nature of the alloy makes it easy to work with and fabricate without complex methods. Finally, the alloy also has excellent resistance to pitting and stress corrosion cracking when properly maintained under the right conditions.

Common Applications for Hastelloy C276 Bars

Chemical Processing Industry

Hastelloy C276 bar is popular in the chemical processing industry due to its exceptional resistance. These media include oxidizing and reducing acids, sulphuric acid, seawater, brine solutions, hypochlorite and chlorine, formic and acetic acids, ferric chloride, and wet chlorine gas. They are also effective against pitting and stress corrosion cracking. This makes them ideal for storage tanks, piping systems that handle corrosive chemicals or seawater, valves, pumps, etc.

Marine Engineering Industry

Due to their superior corrosion-resistant properties, marine engineering applications widely use Hastelloy C276 bars. Thanks to their exceptional resistance to seawater pitting and crevice corrosion, these bars remain durable in highly corrosive seawater conditions. Additionally, they can withstand temperatures up to 200°C (400°F). The frequent exposure to saltwater in heat exchangers, condensers, pumps, and valves necessitates using corrosion-resistant materials like titanium.

Oil & Gas Industries

Hastelloy C276 bars are also very popular in oil & gas industries, where they are used in wells or downhole operations that involve corrosive media such as hydrogen sulfide gas (H2S). The exceptional resistance of these bars towards H2S makes them an ideal choice for downhole tools such as drill collars or stabilizers, which have to operate under extremely hostile conditions deep within the Earth’s crust.
