ASTM B575 Hastelloy C276 Plates and Sheets in Cold Finished UNS N10276 and Hot Rolled Plate Form for Corrosion Resistant Industrial Applications
Hastelloy C276 plates and sheets are popular in challenging industrial applications where the traditional stainless steel and duplex grades would not offer any long-term stability. Being nickel chromium molybdenum alloy with added tungsten, alloy C276 is highly resistant to pitting, crevice and stress corrosion cracking in chloride rich and mixed acidic environments. The material works well in reducing and oxidizing conditions and can therefore be used in chemical processing systems, pollution control equipment, marine structures, thermal processing applications.
Goods produced according to the ASTM B575 guarantee uniform chemical precision and mechanical strength of pressure vessels, heat exchangers, evaporators, scrubber towers and high temperature reactors. UNS N10276 plates offer good resistance to localized corrosion and cold rolled sheets are used to offer smooth surfaces and tight dimension control to allow fabrication and automated forming. Hot-rolled Nickel Alloy C276 plates are usually used in heavy structural elements and equipment that are used to work under highly mechanical stress.
The reduced level of carbon C276 enhances the weldability of the material and reduces the chances of the occurrence of carbide during the joining of the material. This enables the alloy to be employed without doubt in an as-welded environment without losses to corrosion resistance. It has high molybdenum content that guarantees good performance in the reduction of acids, brine solutions, polluted media and high chloride conditions experienced in offshore and petrochemical plants.
Hastelloy C276 plates and sheets produced by Stellar Alloys are subjected to stringent quality inspection procedures and are supplied with complete traceability to facilitate acquisition demands worldwide and project authorisations.
What Are Hastelloy C276 Plates and Sheets?
Hastelloy C276 plates and sheets are high performance nickel chromium molybdenum alloys that are used in service in very corrosive and high temperature environments. These materials are very resistant to pitting, crevice attack and stress corrosion cracking particularly in mixed and chloride-rich process systems. Alloy C276 plate and UNS N10276 sheets are manufactured as per ASTM B575 and are stable in oxidizing and reducing media, so that they can be used in chemical processing units, pollution control equipment, offshore operations and industrial reactors.
The combination of high molybdenum content, chromium balance and added tungsten enhances their durability in aggressive fluids, brine solutions and contaminated process streams. Their low carbon composition improves weldability and allows use in the as welded condition without compromising corrosion resistance. Available in hot rolled plate and cold rolled sheet forms, Hastelloy C276 materials support fabrication, forming, machining and pressure equipment manufacturing for critical industrial applications.
