Introduction to Hastelloy C-276 Plates
Hastelloy C-276 Plates are versatile, solution-annealed nickel-based superalloy plates renowned for exceptional resistance in both oxidizing and reducing environments. With a balanced composition featuring high nickel (~57%), molybdenum (15-17%), chromium (14.5-16.5%), and tungsten (3-4.5%), these plates maintain structural integrity and superior corrosion resistance across a wide temperature range. They comply with key standards like ASTM B575 and excel in welded conditions without post-weld heat treatment, making them a top choice for critical industrial components.

FAQs:
1.What is Hastelloy C-276 and why is it called a universal corrosion-resistant alloy?
Hastelloy C-276 (UNS N10276) is a nickel-molybdenum-chromium-tungsten alloy offering broad-spectrum resistance to both oxidizing and reducing media, outperforming many stainless steels and other nickel alloys in pitting, crevice, and stress corrosion scenarios.
2.What are the main mechanical properties of Hastelloy C-276 plates?
Typical values include ultimate tensile strength ~100-115 ksi (690-790 MPa), 0.2% yield strength ~41-52 ksi (283-355 MPa), and elongation ≥40%. Hardness is around 87-90 HRB.
3.Is Hastelloy C-276 suitable for welding?
Yes — its low carbon content allows excellent weldability using standard methods without requiring post-weld heat treatment, while retaining full corrosion resistance in the heat-affected zone.
4.How does it compare to other alloys like C-22 or 625?
C-276 provides balanced excellence in mixed oxidizing/reducing conditions; C-22 may offer slight advantages in strongly oxidizing environments, while 625 is often used for high-temperature strength.
