AL-6XN® high alloy is a superaustenitic stainless steel which was developed by Allegheny Ludlum Corporation, and has found widespread acceptance in many industrial applications. It’s corrosion-residence has made it any idea choice for applications as broad as acidic juice to absorber systems on power plant SCRs and FGDs.

Unlike flange bolting applications, where the bolts are often only seeing limited environmental interactions, AL6XN® fasteners are often specified in internal, wetted components. Good corrosion resisitance allows for submerged applications in a variety of tank & vessel applications.

Common specifications include:
ASTM A240, ASME SA240 (Plate)
ASTM B691,
UNS N08367

Common available configurations include:
AL-6XN® hex bolts and AL-6XN® hex cap screws
AL-6XN® stud bolts
AL-6XN® finished hex nuts and AL-6XN® heavy hex nuts
AL-6XN® socket head cap screws
AL-6XN® square head set screws
