AL6 Fasteners









AL6 is a super-austenitic alloy, the most abundant element being iron. It is the most popular of the 6% molybdenum alloys. Common usages are in the food processing, pharmaceutical and biotech industries. In most environments, it shows superior corrosion resistance when compared to duplex alloys. Due to the lower nickel content, AL6 is generally more economical than the high nickel alloys. Our AL6 fastener inventory includes hex bolts, nuts and flat washers, primarily in 1/4" to 3/4″ diameters. Please check with us for socket head cap screws, full thread studs, square head set screws and other non-stock items in this material.
