The diameter of Alloy 31 springs that we could do range from 0.30 mm to 3.00 mm.

Our Alloy 31 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 Alloy 31 spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.

Alloy 31 bridges the cost/performance gap between high-performance Ni-Cr-Mo alloys and the 300 series stainless steels.
