Hastelloy C276  is a nickel-chromium-molybdenum alloy that features resistance to corrosion in a wide range of environments. Its high molybdenum content makes it one of the strongest and most versatile nickel-based superalloys available. In particular, the inclusion of molybdenum provides excellent resistance to reductive environments that cause pitting and crevice attack (another type of degradation to which austenitic stainless steels are susceptible).

It is also highly resistant to stress corrosion cracking in chloride-containing solutions. As such, this material is ideally suited to applications in chemical process industries where exposure to corrosive substances is common.

In addition to these critical properties, Hastelloy C276 offers outstanding strength at elevated temperatures. It also resists the formation of grain boundary precipitates during welding, which can negatively impact corrosion performance.

Hastelloy C276: Properties, Benefits, and Common Applications in Harsh Environments

Understanding the specifications, pricing dynamics, and supplier evaluation requirements for Hastelloy C276 is vital for procurement managers seeking to optimize their supply chain strategies. This article delves into the fundamental factors that influence price, best practices for negotiating with suppliers, and future trends to keep in mind for purchasing this versatile alloy.

Wrought Hastelloy C276 is typically delivered in the solution annealed condition, which optimizes its corrosion resistance and ductility. This condition is required for all hot forming operations, and the alloy should be re-annealed after cold forming with an outer fiber elongation of 7% or more. Procurement professionals should also be sure to choose providers with reliable lead times and availability to mitigate delays in delivery, which could impact project timelines and overall cost.
