UNS S30403

304L wire

EN 10204 3.1

304L wire brings low-carbon austenitic compatibility with fabricated stainless equipment 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

Solution annealed; cold worked for strengthened conditions

Solution annealing restores a ductile corrosion-resistant structure, while specified cold work raises strength without precipitation aging.

What we can make in 304L

Coiled wire

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.

Wire on spool

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 wire lengths

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 304L fits — and what matters

Food & Beverage Equipment

Conveyor and washdown-equipment brackets

304L wire is formed into retaining clips, wire pins or spring blanks for conveyor and washdown-equipment brackets. Wire diameter and supplied temper define the forming step and subsequent final-condition treatment. Cleaning liquid can remain under the part; exposed finish and access for cleaning matter at the assembled joint.

Water Treatment & Desalination

Membrane-skid and pump supports

304L wire is formed into retaining clips, wire pins or spring blanks for membrane-skid and pump supports. Wire diameter and supplied temper define the forming step and subsequent final-condition treatment. The water stream, cleaning cycle and retained liquid define exposure at the installed part.

Pumps, Valves & OEM

Actuator mounts and pump baseplates

304L 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.

304L material data
UNS S31603

316L

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.

UNS S17400

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.
17-4 PH wire
UNS N06625

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 304L 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.
