What are the differences between Hastelloy C2000 steel plates and C276 alloy steel plates?
What are the differences between Hastelloy C2000 steel plates and C276 alloy steel plates?
Hastelloy C2000 plates offer broader corrosion resistance, exhibiting excellent performance in sulfuric acid environments due to their copper content. C276 plates, on the other hand, perform better in chloride-rich, oxidizing/reducing environments. Their higher tungsten content and lower chromium content make them suitable for extreme conditions such as marine environments or flue gas desulfurization. The main differences between the two lie in their elemental composition (C2000 plates contain copper, while C276 thin plates contain tungsten and less chromium) and specific application suitability. C2000 plates are more widely used in mixed acids, while medium-thick C276 plates perform better in terms of chloride pitting and crevice corrosion.
What is the composition of Hastelloy C2000?
The design technology of the HASTELLOY C-2000 alloy aims to make it more versatile than conventional nickel-chromium-molybdenum alloys. This is achieved through the use of high chromium content (23 wt.%), high molybdenum content (16 wt.%), and a small but effective amount of copper addition (1.6 wt.%).
What is Hastelloy C2000 plate?
Hastelloy C2000 plate is a versatile corrosion-resistant alloy, primarily composed of nickel, with significant amounts of molybdenum, chromium, and copper. It is specially designed to provide excellent corrosion resistance in a variety of corrosive environments, including both oxidizing and reducing conditions.
What is Hastelloy C276 plate?
Hastelloy C276 alloy plate is a highly corrosion-resistant nickel-molybdenum-chromium alloy designed for operation in extremely harsh environments. It is renowned for its excellent resistance to both strong oxidizing and reducing agents and is widely used in industries with extremely high corrosion resistance requirements.

Hastelloy C2000 Plate vs. C276 Plate: Corrosion Resistance
Both Hastelloy C2000 medium-thick plates and C276 plates exhibit excellent corrosion resistance, but their specific characteristics differ slightly. Hastelloy C2000 thin plates are particularly resistant to chloride-induced stress corrosion cracking and pitting, demonstrating excellent resistance in seawater and other chloride-containing environments. They also resist reducing acids such as sulfuric acid.
On the other hand, Hastelloy C276 plate offers superior resistance to a variety of corrosive media, including oxidizing acids, reducing acids, and chloride-containing environments. Its high chromium content enables it to resist oxidizing agents, while the molybdenum and tungsten content enhances its resistance to reducing acids.
