718 Wire

 718 Wire – High-Performance Nickel-Chromium Superalloy for Aerospace and Critical Applications

718 Wire is a precipitation-hardenable nickel-chromium superalloy wire made from Inconel 718 (UNS N07718) that has outstanding yield, tensile and creep-rupture qualities up to 704°C. TSM Technology produces wire with diameter of 0.5-5.0 mm according to AWS A5.14 ERNiFeCr-2, AMS 5832 specifications. Monthly capacity is 200 tons. Our three facilities have eight manufacturing lines with more than 100 precise equipment, allowing us to maintain tight tolerances and achieve outstanding surface finishes. This alloy is very ductile and resistant to post-weld cracking and hence is a perfect candidate for high-performance fasteners, springs and wire-formed products.

What is 718 Wire?

Our product is engineered to meet the most demanding problems in the harshest environments: material fatigue in heat cycles, oxidation at high pressure and weldability in complex designs. Unlike conventional nickel alloys, it remains ductile at cryogenic temperatures and resists hydrogen embrittlement in sour gas conditions. It offers unprecedented reliability in aircraft turbines, oil and gas downhole equipment and LNG processing seals due to the unique gamma double prime precipitation hardening.

Standards for 718 Wire

The 718 wire corresponds to the worldwide aerospace and welding specifications: ASTM B637, AMS 5832, AWS A5.14 ERNiFeCr-2 and ASME SB-637. These certifications provide traceability, chemical composition conformity and mechanical performance repeatability for mission important applications.

What are the Features of 718 Wire?

· Exceptional Strength: Maintains tensile strength above 965 MPa after double-aging heat treatment.

· Superior Weldability: Resists post-weld age cracking, ideal for complex assemblies.

· Thermal Stability: Performs reliably from cryogenic temperatures to 704°C.

· Corrosion Resistance: Withstands pitting, crevice corrosion, and sour gas environments.

· Ductility: Suitable for cold-heading fasteners before final aging.

Production and Processing Technology

TSM Technology has 3 factories of 60,000 m2 each, equipped with sophisticated forging, rolling and wire drawing equipment. Our process includes controlled atmosphere annealing, tight diameter control and optional surface treatments (sandblasting, electro-polishing, chemical passivation). Each coil is ultrasonically and eddy current tested for internal faults to ensure a 100% issue free dispatch.

Three specialized factories house our wire drawing operations, with each facility equipped with state-of-the-art machinery for precision manufacturing. Quality control laboratories provide immediate testing capabilities to ensure specifications are met.

Quality Inspection

Per ASTM B637 and AMS 5832:

· Chemical Analysis: OES, XRF, ICP verify Ni, Cr, Nb, Mo content.

· Mechanical Testing: Tensile, yield, elongation, hardness per specification.

· NDT: Eddy-current (ET) detects surface cracks; ultrasonic (UT) confirms internal integrity.

· Dimensional Inspection: Laser micrometers measure diameter tolerance ±0.01 mm.

· Surface Inspection: Visual and metallographic grain-size analysis.

Wire is wound on precision plastic or wooden spools, wrapped in moisture-proof film, and packed in export-grade wooden crates. Each package includes material certificates and handling labels. We ship via sea, air, or express courier, with full insurance and customs documentation support.

FAQ

Q: What is the best heat treatment for the product?

A: Solution anneal and double-aging (1325°F for 8 hours, furnace cool to 1150°F, hold total 18 hours) optimizes gamma double prime precipitation.

Q: How does product compare to X-750 wire?

A: Our product has stronger tensile strength and better weldability than X-750.

Q: Is wire resistant to corrosion from seawater?

A: Yes, it has strong resistance to pitting and crevice corrosion in marine environments hence it is ideal for naval fasteners.

Q: What is the typical shelf life of Wire?

A: Indefinite in the annealed condition when dry and clean; the oxide layer resists deterioration from the atmosphere.

Q: Can our product be used for cold-heading?

A: Yes, solution-annealed wire is ductile enough to produce cold-heading fasteners before final aging.
