Manufactured from high-purity nickel-chromium-molybdenum-tungsten alloy, these round bars deliver exceptional resistance to wet chlorine, nitric acid, mixed acids, and chloride-induced pitting. Sankalp Alloys provides precision-engineered Hastelloy C22 Round Bars that adhere strictly to international quality specifications, ensuring reliable performance in the harshest industrial operating conditions globally.
What are Hastelloy C22 Round Bars?
Hastelloy C22 Round Bars (UNS N06022 / DIN 2.4602) are solid cylindrical rods made from a versatile nickel-chromium-molybdenum-tungsten alloy. They are specifically formulated to withstand both oxidizing and reducing media, offering vastly superior resistance to pitting, crevice corrosion, and stress-corrosion cracking compared to standard alloy formulations.
With its high chromium content, Hastelloy C22 provides outstanding resistance to oxidizing aqueous media, including wet chlorine and nitric acid. Sankalp Alloys exports Hastelloy C22 Round Bars in a comprehensive range of diameters, lengths, surface finishes (bright, polished, peeled, and black), and customized tolerances tailored to global engineering standards.

Industrial Applications of Hastelloy C22 Round Bars
Chemical & Petrochemical Processing
Hastelloy C22 Round Bars are heavily utilized in reactors, heat exchangers, chlorination systems, distillation units, and acid recovery plants handling complex oxidizing and reducing chemical streams.
Pharmaceutical & Agrochemical Manufacturing
Essential for synthesis equipment, reaction vessels, precision shafts, and transfer valves where high product purity and resistance to aggressive organic and inorganic acids are critical.
Pollution Control & Flue Gas Desulfurization (FGD)
Widely used in wet scrubbers, ducting components, reheaters, and hazardous waste containment units handling highly corrosive flue gases and industrial effluent solutions.
Pulp & Paper Bleaching Operations
Preferred for bleach plant equipment, chlorination towers, and wash filters handling aggressive chlorine dioxide and hypochlorite bleach solutions.
Nuclear & Power Generation
Used in nuclear fuel reprocessing systems, pickling tanks, waste processing units, and high-reliability mechanical components operating under extreme environmental stress.
Key Benefits & Corrosion Resistance Features
Hastelloy C22 Round Bars are globally preferred in harsh process environments due to their balanced chemistry combining high chromium, molybdenum, and tungsten. This combination imparts unmatched overall resistance to both oxidizing and reducing acids, preventing premature localized corrosion attack under variable processing conditions.
Additionally, these round bars demonstrate extraordinary resistance to chloride-induced pitting, crevice corrosion, and stress-corrosion cracking (SCC). Resisting grain-boundary precipitation during welding, Hastelloy C22 Round Bars maintain excellent corrosion resistance in the heat-affected zone, ensuring superior durability and reduced maintenance downtime for critical industrial systems.
