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

Our 317LM 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 317LM spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.

317LM is a low-carbon, higher molybdenum austenitic stainless steel. It also has higher nickel content than stainless steel grade 317L.
