Corrosion Resistant Alloys
(XM-19) (UNS S20910)
High strength Austenitic with superior corrosion resistance to types 316 and 316L, with approximately twice the yield strength in the annealed condition. Also fully Austenitic, this alloy stays non-magnetic when severely cold reduced. Cryogenic properties are also outstanding as well as elevated temperatures.

(Alloy 218) (UNS S21800)
High strength fully Austenitic alloy that resists galling and wear. Significantly lower cost to extend part life and lower maintenance. The yield strength is twice that of 304 and 316 stainless steels, in the annealed condition. Tensile strengths can be produced in excess of 200 ksi. Chloride pitting is superior to that of type 316, and the oxidation resistance is similar to type 321 at elevated temperatures, and excellent cryogenic impact strength.

HASTELLOY Alloy C-276
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
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
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.
An advanced 7% molybdenum super-austenitic stainless steel offering corrosion resistance in most environments superior to 6% molybdenum super-austenitic stainless steels. In many environments, alloy 27-7MO offers resistance approaching or exceeding that of much more highly alloyed materials such as INCONEL alloys 625, 22 and C276. Applications for this allow are found in the pollution control, power, marine, chemical processing, pulp and paper, pharmaceutical and oil and gas industries.
