Hastelloy is a highly corrosion-resistant alloy recognized for its superior performance in extreme temperatures and aggressive chemical environments. It is extensively used in industries such as chemical processing, petrochemicals, aerospace, and power generation due to its durability and reliability. The most commonly used grades for manufacturing Hastelloy pipes include C276, C22, B2, and X, each tailored for specific industrial needs. Hastelloy pipes are produced in a variety of sizes and wall thicknesses to accommodate diverse application demands.
Manufacturing and quality standards for these pipes are set by leading industry bodies such as ASTM (American Society for Testing and Materials) and ASME (American Society of Mechanical Engineers). Key specifications include ASTM B622 for seamless Hastelloy pipes and ASTM B619 for welded pipes, outlining requirements for chemical composition, mechanical properties, and testing protocols to ensure high performance and safety.
