Corrosion Resistant Alloys

HASTELLOY® alloy C-276 (UNS N10276) Ni 57.0, Mo 16.0, Cr 15.5, Fe 5.5, W 3.8 Outstanding corrosion resistance in reducing and oxidizing environments. Maintains corrosion resistance in welded condition. Excellent resistance to pitting and stress-corrosion cracking (SCC).
Widely used in severest environments in chemical processing, pollution control, pulp and paper.

HASTELLOY® alloy B-2 (UNS N10665) Ni 68, Mo 28, Fe 2, Co 1, Cr 1 Significant resistance to reducing environments. This alloy also provides resistance to pure sulfuric acid and a number of non-oxidizing acids. Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced SCC.
One of its advantages is the heat affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance. Chemical processing industry involving sulfuric, phosphoric, hydrochloric and acetic acid. Temperature uses vary from ambient to 1500°F depending on the environments.

HASTELLOY® alloy C-22® (UNS N06022) Ni 58, Cr 22, Mo 13.0, Fe 3.0, W 3.0 Better corrosion than C-276 in select environments. Resistance to a wide range of organic acids and the resistance to chloride-induced SCC, and other reducing chemicals. Also has resistance to some oxidizing environments.
Recommended for welding filler metal for general corrosion resistance in many applications.

Nickel 200 / 201 (UNS N02200 / N02201) Ni 99.6 C 0.08 Commercially pure wrought nickel, good mechanical properties, excellent resistance to many corrosives. Nickel 201 has low carbon (0.02% max.) for applications over 600 degrees F (315 degrees C).
