Overview
CG6MMN, known as NITRONIC 50 in its wrought form, is a cobalt-based cast alloy that offers a compelling combination of high strength and excellent corrosion resistance. This austenitic stainless steel exhibits low magnetic permeability, even at low temperatures, making it suitable for applications where magnetic sensitivity is a concern. Its corrosion resistance surpasses that of typical 300 and 400 series stainless steels, providing enhanced protection in a variety of environments. CG6MMN is a valuable choice for applications requiring a combination of strength, corrosion resistance, and low magnetic permeability, making it suitable for diverse industries and demanding conditions.
