FEATURES
Alloy B-2 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also has significant resistance to reducing environments like sulfuric, phosphoric, acetic acids and other nonoxidizing media. Alloy B-2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Alloy B-2 has poor resistance to oxidizing environments, therefore, it should not be used where ferric or cupric salts are present as these salts may cause rapid corrosion failure.
APPLICATIONS
Equipment handling reducing chemical environments; and chemical process industry involving hydrochloric, sulfuric, phosphoric and acetic acids.

FEATURES
Alloy C-4 has outstanding high-temperature stability, and has excellent resistance to stress-corrosion cracking and oxidizing atmospheres up to 1040℃. It has exceptional resistance to a wide variety of chemical process environments, including hot contaminated mineral acids,solvents, chlorine and chlorine contaminated media (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions.
APPLICATIONS
Chemical processing involving wet chlorine, hypochloric acid, hydrochloric acid, acetic acid and acetic anhydride; flue gas scrubber systems; pickling operations; and electro-galvanizing.
