The diameter of 17-7Ph springs that we could do range from 0.30 mm to 3.00 mm.
Our 17-7Ph 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 17-7Ph spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.
17-7Ph is a precipitation hardenable chromium-nickel-aluminum stainless steel.
