Custom Multi-Grade Stainless Steel Straight Wire 0.15-12mm
Product Introduction
TOPONE Wire supplies custom stainless steel straight wire for industrial manufacturing, wire forming and metal component production. Wire is straightened and cut to length from selected stainless steel grades, in diameters from 0.15 mm to 12 mm.
Straight wire differs from coil wire in one practical respect: the material has to arrive at the forming station with a defined straightness and a defined cut length. Both values are specified on the drawing, because they decide whether automated feeding runs without jamming or misfeed.
Grade, diameter, straightness tolerance, cut length, surface condition and mechanical properties are therefore treated as one specification set, not as independent options.

How Grade Choice Affects the Finished Component
201 and 202 – Chromium-Manganese Austenitic
Lower-nickel austenitic grades used where corrosion demand is moderate and cost control matters. Both are magnetic to some degree after cold working, which should be checked where the component is used near sensors or magnetic fixtures.
302, 304 and 304Cu – Austenitic, General Purpose
304 is the most widely specified grade for industrial components and general wire forming. 302 offers higher carbon for strength where forming allows it. 304Cu is copper-bearing and is considered where reduced work hardening supports cold heading or multi-stage forming.
316 and 316L – Molybdenum-Bearing Austenitic
Considered where chloride exposure, cleaning agents or chemical environments demand higher corrosion resistance than 304. 316L carries lower carbon and is usually preferred for assemblies that are welded after forming.
410 and 430 – Ferritic and Martensitic
Magnetic grades with lower alloy content, used for fasteners and components where moderate corrosion resistance and magnetic behaviour are acceptable. 410 can be hardened by heat treatment; 430 is suited to forming and drawing operations.
Product Advantages
1. One Supplier Across 0.15–12 mm
Fine wire components and larger pins can be sourced from the same production route. This matters when a part family spans several diameters and the buyer wants one inspection standard across the range.
2. Straightness and Cut Length Defined per Drawing
Straightness limit, cut length and end condition are stated in the order instead of being left to general mill tolerance. Automated feeding and magazine loading depend on these two values more than on any other parameter.
3. Nine Grades Under One Specification Format
Grade can be selected against the service environment rather than against what happens to be in stock, while diameter, straightness and packing stay on a common format between orders.
4. Surface and Mechanical Condition Stated Before Production
Bright, annealed or specified surface, plus tensile strength and temper, are fixed at quotation. What is inspected at dispatch is therefore the same set of values that was quoted.
5. Lot Traceability
Material grade and inspection records are referenced to the order, so a later complaint can be traced back to the production lot and to the agreed acceptance criteria.
Applications of Stainless Steel Straight Wire
Industrial Metal Components
Straight wire serves as raw material for components with defined diameter and cut length, such as shafts, pins and spacers. The selected grade should meet the mechanical and environmental requirements of the component.
Wire Forming
Clips, hooks, retaining rings and bent parts are formed from straight cut lengths where feed consistency matters. Straightness tolerance and cut length tolerance should be specified together with the forming process.
Fasteners and Cold-Headed Parts
Where the process involves heading or multi-stage forming, grade and temper are selected for deformation behaviour, and 304Cu or annealed conditions are frequently evaluated.
Metal Fabrication and Assembly
Cut lengths are used as welding consumable cores, support pins and locating elements, where cut length accuracy and end condition affect assembly fit.
Quality Control and Inspection
Inspection points are set according to the specification agreed at order stage, not applied afterwards. A typical sequence covers incoming grade verification, diameter and tolerance measurement, straightness check against the agreed limit, cut length check, surface inspection, and tensile testing where required.
Records are kept per lot and referenced to the order number. Sampling level, acceptance criteria and report format are agreed before production, which prevents later disagreement about what "acceptable" means.
Packing and Delivery
Straight wire is supplied in bundles with protective wrapping. Bundle mass, end protection and marking are agreed with the order, because handling differs between manual assembly and automated feeding equipment.
Sea-freight packing with moisture protection is available on request. Lead time depends on grade, diameter, cut length and quantity, and is confirmed at order acknowledgement rather than assumed at inquiry stage.
How to Specify a Straight Wire Order
- Material grade – 201, 202, 302, 304, 304Cu, 316, 316L, 410 or 430.
- Wire diameter – nominal diameter and required dimensional tolerance.
- Straightness and cut length – straightness limit, finished length and acceptable deviation.
- Surface and mechanical condition – surface finish, tensile strength, temper and applicable standard.
- Quantity and packing – order quantity, bundle mass, marking and delivery terms.
A drawing or detailed specification shortens the review, because each of the five points above maps directly to a production and inspection parameter.
Frequently Asked Questions
Which stainless steel grades are available?
Listed options are 201, 202, 302, 304, 304Cu, 316, 316L, 410 and 430. Availability for a specific diameter and specification is confirmed at quotation.
Can the wire be cut to a specific length?
Yes. Cut length and its tolerance are agreed per order, together with straightness limit and end condition.
What straightness can be supplied?
Straightness is defined as a limit against the agreed length, so feasibility depends on diameter, length-to-diameter ratio and grade. State the required limit and the wire will be evaluated against it.
Are material certificates and inspection reports available?
Yes, where the report type and scope are agreed at order stage, so that the documents match the acceptance criteria used at dispatch.
Request a Straight Wire Specification Review
Send the required grade, diameter, cut length, straightness tolerance, surface and mechanical requirements, and application. A drawing or detailed specification allows the specification set to be reviewed as a whole and suitable options confirmed.
