The diameter of 317LMN springs that we could do range from 0.30 mm to 3.00 mm.

Our 317LMN springs come in a variety of surface finishes from bluing to clear or yellow zinc electroplating, electrolytic nickel, powder coating and zinc phosphate coating always executed by specialized subcontractors

At the end of the manufacturing and stress relief cycles, clients require different and very specific types of treatments in order to improve 317LMN spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.

317LMN is non-magnetic in the annealed condition
