Cold‑Drawn Titanium Spring Wire Gr5 Gr12 For Corrosion‑Resistant Compression Spring
Опубликовано Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd от 2026-10-25
1. Product Identity
Based in Shaanxi Baoji China, titanium pressure spring wire is high‑strength cold‑drawn precision titanium wire specially engineered for spring manufacturing, different from common titanium welding wire. Multi‑pass cold drawing and stress‑relief tempering process guarantee stable spring‑back performance and long cyclic fatigue life. Gr5 delivers high strength for heavy‑load springs; Gr12 provides excellent corrosion resistance under reducing acid‑chloride mixed medium. Widely used for marine equipment compression springs, offshore instrument elastic components, chemical anti‑corrosion snap rings and corrosion‑resistant elastic fasteners. We supply spool‑wound wire, straight cut rod, support custom wire diameter and tensile strength grade for spring workshop.

4. Mechanical & Corrosion Performance
-
Tensile strength range can be adjusted by cold‑draw deformation rate and tempering procedure for spring requirement.
-
Gr5: High tensile strength, good elastic modulus, fit for heavy‑load compression spring under seawater environment.
-
Gr12: Outstanding anti‑corrosion performance in mixed chloride‑reducing acid medium, suitable for chemical plant elastic components.
-
Dynamic feature: Strict tempering treatment reduces residual internal stress; avoids spring relaxation and permanent deformation under long‑time cyclic compression load.
-
Corrosion fatigue note: Surface flaw must be minimized; scratch or nick will become fatigue crack initiation point under cyclic load in corrosive medium.
5. Full Size Range
-
Wire diameter: Custom fine‑to‑medium diameter according to spring design requirement.
-
Supply form: Large spool coil for automatic spring coiling machine; straight cut pieces for manual processing.
-
Custom options: Target tensile strength grade, special surface finish, fixed‑length cutting, tight diameter tolerance.
6. Surface Treatment Options
-
Drawing bright surface: Smooth as‑drawn finish, preferred for spring coiling, minimize surface micro‑notches.
-
Pickling surface: Remove drawing lubricant residual and oxidation layer for special chemical service.
-
Ultrasonic degreasing: Eliminate drawing oil residue before spring manufacturing process.
7. Material Comparison: Titanium Spring Wire vs Stainless Steel Spring Wire

Item
|
Titanium Spring Wire(Gr5/Gr12)
|
316L Stainless Spring Wire
|
|
Corrosion under seawater cyclic load
|
Resist corrosion‑fatigue failure
|
Easy pitting then fatigue crack initiation
|
|
Density
|
Lightweight, lower spring inertia
|
Higher density, heavier elastic assembly
|
|
Spring‑back stability
|
Good after dedicated tempering process
|
Good for general atmospheric condition
|
|
Limitation
|
Higher raw‑material cost
|
Fail fast in high‑chloride corrosive environment
|
Titanium spring wire solves corrosion‑fatigue failure problem which frequently occurs for stainless steel springs under seawater or chemical cyclic‑load working condition.
8. Strict Quality Control & Test Items
-
Raw titanium rod incoming chemical composition inspection.
-
Monitor cold‑draw deformation rate and stress‑relief tempering temperature‑time curve.
-
Per‑lot tensile test to verify final wire mechanical properties.
-
Surface full inspection: Check micro‑crack, nick, scratch which impact fatigue life.
-
Diameter continuous online dimension monitoring during drawing production.
-
Issued documents: EN10204 3.1 MTC, mechanical tensile report, batch traceability record.
9. Export Packaging & Shipment
-
Inner packing: Anti‑rust film wrapped spool, separate protective partition to prevent wire surface scratch.
-
Outer packing: Fumigated export carton or wooden case, prevent spool collision and wire knotting in transit.
-
Marking: Print grade, wire diameter, tensile strength grade, batch number on each spool label.
-
Trade terms: FOB, CIF, DDP; air freight for small‑batch fine wire, sea freight for bulk spool orders.
