Introduction
Alloy 926 is a super-austenitic molybdenum stainless steel that exhibits excellent resistance to a variety of highly corrosive environments. The combination of molybdenum and nitrogen in its composition resists pitting and crevice corrosion, while copper improves sulfuric acid resistance, and nitrogen improves yield and tensile strengths.
The following datasheet will provide more details about alloy 926.
