Alloy 400 Fasteners
Alloy 400 is versatile and is used to resist both acids and alkalis. Seawater applications are common.
A variant is Alloy 405 (UNS N04405). It contains slightly more sulfur, which improves machinability.
Stock: Hex bolts, nuts, washers, socket cap screws, machine screws. Lock washers made from Alloy 500.
