The diameter of AISI 347 springs that we could do range from 0.30 mm to 3.00 mm.
Our AISI 347 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 347 spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.
AISI 347 is a columbium/tantalum stabilized austenitic stainless steel.
