Stainless Steel Wire
Stainless steel wire (thread) is a fine wire product with a diameter typically less than 8 millimeters, which is made by repeatedly cold drawing and extruding stainless steel wire rods. It is the final or semi-finished form of various precision metal products.

Product Introduction

Stainless Steel Wire is a versatile, semi-finished product manufactured by drawing stainless steel rod through a series of progressively smaller dies. This cold-working process imparts high tensile strength, excellent surface finish, and precise dimensional tolerances. Available in a vast range of diameters, tempers, and surface finishes, it serves as a critical raw material and component across virtually every industry.

The properties of the wire are directly derived from its base alloy (e.g., 304, 316, 430, 17-7 PH). It can be supplied in various conditions—annealed (soft) for forming, half-hard for spring temper, or full-hard for maximum strength—and in forms such as spools, coils, or straight lengths. From tiny springs in medical devices to massive cables in suspension bridges, stainless steel wire is the invisible backbone of modern engineering and manufacturing.

Common Options / Grades

Notes / Significance

Base Alloy (Determines Core Properties)

Austenitic: 304, 304L, 316, 316L (Corrosion resistance, non-magnetic)
Martensitic: 410, 420, 431 (Hardenable, magnetic, for springs/cutlery)
Ferritic: 430 (Magnetic, economical, for general use)
Precipitation-Hardening: 17-7 PH, 630 (17-4PH) (Ultra-high strength after heat treatment)

The alloy choice dictates corrosion resistance, magnetism, and maximum achievable strength.

Diameter Range

Ultra-Fine: < 0.10 mm
Fine: 0.10 - 1.0 mm
Medium: 1.0 - 5.0 mm
Heavy: > 5.0 mm (up to ~20+ mm for cable)

Diameter directly impacts minimum bend radius, tensile load, and application (e.g., filament vs. cable).

Temper / Condition

Annealed (Soft): For severe forming/rewinding.
Hard Drawn: High strength, spring properties.
Spring Temper: Optimized elasticity and fatigue resistance.
Solution Treated: For PH grades, ready for aging.

Condition defines tensile strength, yield strength, and elongation. It is application-critical.

Surface Finish

Bright: Standard, smooth finish.
Galvanized: Zinc-coated for enhanced corrosion resistance.
Tinned: Tin-coated for solderability/corrosion resistance.
Polished: Mirror-like for decorative applications.

Affects aesthetics, corrosion resistance, lubricity, and coating adhesion.

Form / Packaging

Coils: (Open, pancake, barrel-pack) for automated feeding.
Spools/Reels: For uniform payout, long lengths.
Straight Lengths: Cut rods for machining/fasteners.

Determines handling, storage, and compatibility with production equipment.
