Split lock washers are made mostly from coils of wire. Lock washers made from coil are subject to high volume production runs. Steel and stainless steel lock washers become work hardened in the manufacturing process and possess more strength and spring than the raw material.
Lock washers made from nickel-based alloys and stainless, other than 18-8 or 316, are generally machined from plate stock. There is not enough demand to make these parts from coil. Washers made from plate are not as strong as those made from coil and cannot be reused.
Nickel Systems maintains an inventory of split lock washers in Hastelloy® (Alloys C276, C22, B2), Carpenter® 20 (Alloy 20), 18-8 and 316 Stainless. Current inventory includes 317L Stainless, K-Monel® (Alloy 500) and AL6XN®. Additionally, we can re-machine certain sizes to produce hi-collar lock washers for use with socket head cap screws.
