0.3mm 316 Stainless Steel Spring Wire for Precision Springs with Fine Diameter and Corrosion Resistance

Product Introduction

TOPONE Wire supplies 0.3mm 316 stainless steel spring wire for precision spring manufacturing and fine wire-forming applications where material grade, wire diameter control, and corrosion resistance are important considerations. ecer

Made from AISI 316 / SUS316 stainless steel, this fine-diameter spring wire is suitable for small precision springs, compression springs, torsion springs, extension springs, and customized wire components. The molybdenum-containing composition of 316 stainless steel helps improve resistance to pitting and crevice corrosion in many chloride-containing environments.

The wire is available in a 0.15-12mm diameter range, with bright and soap-coated surface options according to different spring forming and processing requirements. ecer

For precision spring applications, wire diameter, tolerance, surface condition, mechanical properties, spring design, and working environment should be considered together to select the suitable specification.
