Technical Overview

The Hastelloy C22 alloy is a high-performance austenitic material primarily composed of nickel, chromium, molybdenum, and tungsten, engineered to withstand the most aggressive corrosive environments. It demonstrates outstanding resilience against pitting, crevice attack, and stress-related corrosion, making it highly effective in both oxidizing and reducing environments. Chromium provides excellent protection against oxidizing agents, while the presence of molybdenum and tungsten strengthens the alloy’s performance in corrosive, reducing environments. Hastelloy C276, another widely used variant, exhibits outstanding corrosion resistance even at elevated temperatures. Its stable microstructure helps prevent grain boundary precipitation, making it suitable for welding and thermal applications without compromising mechanical integrity. These metallurgical properties make Hastelloy Round Bars an excellent choice for challenging operating environments.

Applications & Industry Use

Engineered for critical applications, Hastelloy Round Bars from Kvn Steels serve a broad range of industries that demand high corrosion resistance, structural integrity, and long service life. These include the offshore oil and gas sector, petrochemical refineries, chemical processing plants, power generation units, marine and seawater equipment, heat exchangers, and pulp and paper industries. Their application extends to specialized components in construction, automotive, and infrastructure development, where exposure to extreme chemicals, heat, and pressure is common. The combination of mechanical strength, corrosion resistance, and fabrication versatility positions these alloys as a trusted material choice across our key supply regions—India, UAE, Saudi Arabia, Kuwait, Qatar, Oman, Iran, and Iraq. With a focus on quality, compliance, and service, Kvn Steels continues to deliver engineered alloy solutions that stand the test of time.
