Wire is made in outgassing, pickled conditions. Its out-of-roundness cannot override the features of its diameter. Its surface must be clean and clear, without non-pickled places, black spots, colors of tarnish. Minor tears, small guide marks, backfins of a depth that do not exceed sizes noted in table are allowed.
Note:presence of certain small defects is allowed according to GOST. If a wire has a diameter of up to 3,0 mm, defect depth must not exceed 0,1 mm; at a diameter that higher than 3,00 mm it must no exceed 0,2 mm. Correction of pollution and surface defects are done with a method of pickling treatment according to GOST. There is allowed further peeling-off of small single-piece pollutions. Pickling treatment of certain coils with further repeated degasifying are also allowed.
General scope of macrosection with defined depth exceeding defect during a process of metallographic examination cannot be higher than 10% of macrosection general scope of inspection lot.
Supply
Titanium wire is delivered in coils which diameter must not exceed 900 mm. Turned into coil wire must not stick together; it must not have a coil camber up to 100° according to GOST. Distortion of titanium wire which appears at coil annealing is not a flaw. Coil weight along with a wire cannot be more than 50 kg. If coil composes of a few pieces, a length of every piece must not be less than 10 m.
Mechanical characteristics
| Grade of titanium alloy | Percentage extension, % not more than | Diameter of wire, mm | Ultimate resistance MPa (kgf\mm sq.) |
| Gost VT2 | 13.0 | 1.6 — 7.0°С | 460−655 (47−67) |
Marking
Every coil of wire must have attached mark that will define:
— number of batch and smelting;
— inspection stamp;
— release date;
— name of manufacturer and trade mark:
— conventional symbol of wire;
— marking of standard
Packaging
Every coil of wire must be tightly bounded with soft titanium wire. Then, it must be packaged in a clean paper. It is wraparound with bagging at the top. Wire that is rolled into coil must be joined with natural or synthetic binder according to requirements of standard technical documents.
Weldability
| weldable without limits | welding is done without further heat treatment of heating |
| limitedly weldable | welding is possible at heating to 100−120°С and last heat treating |
| hardly weldable | in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treating (annealing) after welding |
