UNS S17400

17-4 PH wire

ASTM A564

17-4 PH wire brings aging-controlled strength and hardness 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 treated, then aged to the specified H condition

Condition A is the solution-treated starting state; aging to H900, H1025 or H1150 sets the final strength–toughness balance.

What we can make in 17-4 PH

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

Solution treatment and the specified aging condition are recorded against the production lot; final dimensions are checked after thermal processing.

Finished geometry

Diameter, surface defects, coil set and packaging are checked against the intended forming process.

Where 17-4 PH fits — and what matters

Industrial Machinery & Automation

Machine frames and positioning fixtures

17-4 PH 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 frames

17-4 PH 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 baseplates

17-4 PH 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.

17-4 PH 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 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.

UNS S31803 / S32205

Duplex 2205

Duplex strength and chloride-corrosion resistance.

Connection priority
The strength or spring response of the formed wire
S31803 or S32205
The specified UNS fixes the chemistry. Solution treatment, section size and the ordered mechanical or corrosion tests establish the final duplex condition. Include liquid retained at tight bends and the original wire surface after forming in the exposure description.

Questions about 17-4 PH 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.
