Welcome to Golden Steel Material Let’s Talk
Hastelloy C22 (UNS N06022) Plates, engineered to the ASTM B575 standard, represent one of the most versatile and high-performing nickel-chromium-molybdenum-tungsten alloys available today. Designed to offer superior protection over other nickel-based alloys like C-276 and Alloy 625, Hastelloy C22 provides an exceptional balance of resistance to both oxidizing and reducing environments. With its significantly higher chromium content, this alloy excels in resisting oxidizing aqueous media, including wet chlorine and solutions containing nitric acid or oxidizing acids with chloride ions. It is the definitive solution for chemical processes where "upset" conditions occur or where multi-purpose equipment must handle varying corrosive streams.
The technical sophistication of ASTM B575 Hastelloy C22 is most evident in its unparalleled resistance to localized corrosion. It provides the highest level of immunity to pitting, crevice attack, and stress-corrosion cracking in the most aggressive chemical environments. This makes it an essential material for pharmaceutical manufacturing, pesticide production, and wastewater treatment plants. Furthermore, its excellent thermal stability ensures that the alloy maintains its corrosion resistance even in the welded condition, preventing intergranular attack in the heat-affected zones of reaction vessels, heat exchangers, and scrubbers. Whether utilized in green-death solutions or severe marine exhaust systems, Hastelloy C22 plates deliver an uncompromising performance that ensures the safety and longevity of critical industrial infrastructure.
