Round Wire: Custom Precision Stainless Steel Wire

Explore our range of stainless steel round wire, drawn from a robust 10mm wire rod down to an ultra-fine 0.018mm diameter for the most demanding technical applications. From heavy-duty SS410 wire rod built for fasteners and springs to biocompatible SS316L fine wire used in medical devices and precision electronics, every diameter in our range holds the same ±0.01mm tolerance and 1,200 tons/month production capacity your supply chain can rely on.

ISO 9001 Certified

Strict quality control protocols for every batch produced.

Custom Geometry

Tailored slot widths and wire profiles to your specs.

Global Shipping

Fast and reliable export to over 50 countries worldwide.

Wire Rod & Spring Wire for Fasteners and High-Stress Components

For fasteners, springs, and structural components that need to hold up under repeated stress, our Stainless Steel Wire Rod & Spring Wire is available in SS304, SS316, and SS410 for applications that call for specific heat treatment and hardness. Offered as Soft Wire, Hard Wire, Spring Wire, or Electrode Wire, every diameter from 0.018mm to 10mm holds the same ±0.01mm tolerance, making it a reliable base material for bicycle spokes, binding wire, and TIG/MIG welding electrode feed.

High-Precision Round Wire for General Industrial Applications

When a project calls for a dependable, general-purpose round wire rather than a specialized grade, our High-Precision Stainless Steel Round Wire covers SS304 and SS316/316L across the same 0.018mm–10mm range. Its uniform circular cross-section distributes force evenly during bending, twisting, or welding, which is why it shows up in bicycle spokes, wire rope, and industrial mesh production lines that need consistent mechanical properties batch after batch.

Fine Round Wire for Medical, Electronics, and Aerospace Precision

For applications where even a few micrometers of variance matters, our Fine Stainless Steel Round Wire is drawn down to a minimum diameter of 0.018mm while holding the same ±0.01mm tolerance as our standard round wire. The SS316 and SS316L grades in this line are biocompatible, which is why this wire is used in medical instruments and surgical devices as well as precision electronics and aerospace components.

Frequently Asked Questions

Find answers to common questions about our products, customization, and delivery.

We manufacture stainless steel round wire from 0.018mm to 10mm in diameter, held to a ±0.01mm tolerance across the full range. Wire is available as Soft Wire, Hard Wire, Spring Wire, or Electrode Wire, with surface finishes available in Bright, Cloudy, Matte, Plain, or Black depending on your application.
We produce round wire in SS304, SS316, SS316L, and SS410. SS410 is typically selected when a part needs specific heat treatment and hardness, SS316L is used when higher corrosion resistance or biocompatibility is required, such as for medical or surgical applications, and SS304/SS316 cover most general industrial fastener, spring, and mesh applications.
Standard lead times are 7–15 days for in-stock specifications and 10–20 days for custom orders. Every batch is checked against the ±0.01mm tolerance through dimensional and surface inspection, and our facility is ISO 9001 certified. Whether we can offer free samples depends on your planned order quantity — for larger production volumes we provide samples free of charge; for smaller trial quantities, a sample fee may apply. For minimum order quantity, our team will quote based on your specific diameter, grade, and volume requirements.
