Product Packaging
Wire is protected in coils, spools or straight-length bundles with moisture-resistant wrapping and labels for grade, diameter, heat and quantity. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Chemical processing equipment
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Marine and desalination systems
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Industrial fabrication and precision components
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Specification & Selection Notes
Product-standard boundary
ASTM B863-23 covers titanium and titanium-alloy wire and identifies Grade 4 as UNS R50700 unalloyed titanium. The RFQ must still state the exact revision, wire diameter and tolerance, straight length or coil/spool format, condition, surface, cast or helix requirements where relevant, and required documentation.
Inspection and traceability
Verify Grade 4 / UNS R50700 heat identity, chemistry, tensile properties and hardness where required, diameter and tolerance, straightness or cast/helix, surface, spool or coil data, marking, MTC and heat/lot traceability. Add cleanliness, special surface, NDT or customer witness only with an agreed method and acceptance criteria.
Selection boundary
Grade 4 is the highest-strength commonly specified commercially pure titanium grade. Select it when the required minimum strength and CP titanium material family are supported by the design, while recognizing that forming latitude generally differs from lower-strength Grade 1 or Grade 2 wire.
Technical FAQ
Is Grade 4 titanium wire the same as welding filler wire?
No. ASTM B863 Grade 4 describes wrought wire material. Welding filler must be selected by the qualified WPS and the applicable filler classification; a base-metal grade name alone does not establish filler acceptance.
How does Grade 4 wire differ from Grade 2 wire?
Both are commercially pure titanium grades, but Grade 4 has higher specified strength and generally less forming latitude. Chemistry, mechanical requirements and certificates are not interchangeable.
What information is needed to quote Grade 4 wire?
Provide ASTM B863 revision, Grade 4 / UNS R50700, diameter and tolerance, straight length or coil/spool format, condition, surface, forming or machining use, quantity, testing, MTC and destination.
FAQ
What information is required to quote Grade 4 Titanium Wire?
Provide the titanium grade, product form, dimensional standard or drawing, thread or critical dimensions, quantity, surface treatment, mating parts, service conditions and required inspection documents.
Which standards apply to Grade 4 Titanium Wire?
ASTM B863 / ASME SB863
How are Grade 4 Titanium Wire inspected?
MTC review, dimensional and surface inspection, heat/lot traceability, with PMI or applicable NDT when specified
