11Cr-10Ni Austenitic Stainless (var. 6)

An austenitic stainless steel with 11% chromium and ~10% nickel, strengthened by molybdenum and minor additions of aluminum and titanium for enhanced hardness and corrosion resistance. This variant represents a lean-chromium, lean-nickel composition positioned between conventional 300-series stainless steels and duplex grades, offering a balance of formability and strength without the cost of higher nickel loadings. Engineers select this alloy for moderately corrosive environments where standard austenitic grades may be overspecified or where cost control is critical, particularly in applications requiring decent strength combined with ductility and weldability.
