The diameter of AISI 348 springs that we could do range from 0.30 mm to 3.00 mm.

Our AISI 348 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 AISI 348 spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.

AISI 348 is sightly tougher than grade 304 stainless steel.
