430 wire
EN 10204 3.1
430 wire brings ferritic stainless performance for mild industrial exposure to formed pins, retainers and specified spring components. Diameter, supplied temper and surface quality determine the feasible forming and final-treatment route.

Which standard is on your order?
Heat Treatment
AnnealedAnnealing reduces work hardening and restores ductility for the specified supplied condition.
What we can make in 430
Coiled wire
Use for repeated spring coiling, wire forming and cold-heading feeds. Wire condition must match the next operation: ductile feedstock for heavy forming, spring temper where the design needs elastic strength.
Spooled wire
Use for controlled payout into automatic feeding and winding equipment. Spool dimensions and winding quality affect uninterrupted feeding as much as wire diameter.
Straight lengths
Use for individual pins, straight wire components and small batches without a coil-feeding line. Straightness and cut-end condition reduce preparation before machining or forming.

Supply & preparation
Coil, spool or straightened lengths are identified with diameter and supplied temper; spring wire and heading wire are different orders.
Material condition
The final annealed or specified strengthened condition is linked to the lot; an aging treatment is not assumed for a solid-solution alloy.
Finished geometry
Diameter, surface defects, coil set and packaging are checked against the intended forming process.
Where 430 fits — and what matters
Industrial Machinery & Automation
Machine frames and positioning fixtures430 wire is formed into retaining clips, wire pins or spring blanks for machine frames and positioning fixtures. Wire diameter and supplied temper define the forming step and subsequent final-condition treatment. Alignment, operating cycles and replacement access define the working interface.
Automotive & EV Manufacturing Equipment
Assembly fixtures and test-rig frames430 wire is formed into retaining clips, wire pins or spring blanks for assembly fixtures and test-rig frames. Wire diameter and supplied temper define the forming step and subsequent final-condition treatment. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Pumps, Valves & OEM
Actuator mounts and pump baseplates430 wire is formed into retaining clips, wire pins or spring blanks for actuator mounts and pump baseplates. Wire diameter and supplied temper define the forming step and subsequent final-condition treatment. Repeated maintenance makes fit, engagement and access part of the component specification.
Same wire. Different material priorities.
430 material data316L
Molybdenum-bearing stainless performance in wet equipment.
- Connection priority
- The strength or spring response of the formed wire
- Washdown and retained cleaner
- Cleaner concentration, rinse quality and deposits determine the exposure in covered joints. The low-carbon designation does not independently establish a fastener strength class. Include liquid retained at tight bends and the original wire surface after forming in the exposure description.
17-4 PH
Aging-controlled strength and hardness.
- Connection priority
- The strength or spring response of the formed wire
- H900 versus H1150
- The aging condition changes the balance of strength, hardness and toughness. A replacement part needs the specified H condition, especially where contact wear and shock load occur together.
Inconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- The strength or spring response of the formed wire
- Annealed or solution-annealed 625
- The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at tight bends and the original wire surface after forming in the exposure description.

Questions about 430 wire
Can heading wire and spring wire be ordered by grade alone?
Their forming and working-strength requirements differ. Specify diameter, supplied temper, surface condition and the intended operation so the wire can follow the required manufacturing route.
