Hastelloy C-276

As a leading supplier and manufacturer in China, HZW supply cost-effective Hastelloy C-276 alloys products.

Hastelloy C-276 (UNS N10276 / W.Nr. 2.4819) is a very commonly used nickel-chromium-molybdenum alloy. Among superalloys, it is known for its high molybdenum content.

First, as a corrosion-resistant element, molybdenum brings very high resistance to reductive corrosion to the alloy. By combining with nickel and chromium, Hastelloy C-276 has very good overall corrosion resistance. Compared with stainless steel, its excellent resistance to stress corrosion cracking in chloride-containing solutions cannot be replaced.

Secondly, the solid solution strengthening effect of molybdenum and tungsten elements is very obvious, and they bring very high strength to Hastelloy C-276 alloy. Like other nickel alloys, Hastelloy C-276 has good ductility. It is easy to shape and weld.

Hastelloy C-276 alloy is well suited for gas melting arc (GMA/MIG), gas tungsten arc (GTA/TIG) and shielded metal arc (SMA/Stick) welding processes. Hastelloy C-276 is ideal for marine applications. Its corrosion resistance makes it resistant to various corrosive substances in flowing seawater for a long time. However, Hastelloy C-276 also has good overall performance at high temperatures. It is very suitable for the preparation equipment of various corrosive chemicals or the reactor of various acidic substances.

Hastelloy C-276 alloy exhibits extremely high resistance to chloride-induced pitting and crevice corrosion. These forms of corrosion are particularly prone to occur in austenitic stainless steels.

Similar to other nickel alloys, one of the key features of Hastelloy C-276 is its resistance to chloride-induced stress corrosion cracking.

Hastelloy C-276 has demonstrated exceptional ability to resist seawater corrosion. Sea water is the most common salt water solution. It is widely used in marine and offshore oil rigs and as a coolant in coastal installations.

Hastelloy C-276 is a solid solution alloy. This alloy has good solid solution strengthening effect. Hastelloy C-276 is stronger than stainless steel, and even stronger than most solid solution alloys. Therefore, it is also easier to increase strength through cold working.
