Wire is made in outgassing, pickled conditions. Its out-of-roundness can not override features of its diameter. Its surface must be clean and clear, without non-pickled places, black spots, colours of tarnish. Minor tears and dark non-pickled places on its surface are allowed. Small guide marks, backfins of a depth that do not exceed sizes that are noted in a table are also allowed.

Note: there are allowed a presence of small separate defects on a surface at wire diameter of up to 3.0 mm of depth

Cleaning of contaminations, surface defects are done by means of pickling treatment, dressing. There are allowed further dressing of small separate contaminations and pickling treatment of certain coils with repeated degasifying. General scope of macrosection with defined exceeding of defect depth during a process of metallographic examination cannot be higher than 10% of macrosection general scope of inspection lot.


Titanium wire is delivered in coils which diameter must not exceed 900 mm. Wire waps in coil must not stick together. They must have coil cambers up to 100°. Distortion of titanium wire, which appears at coil annealing, is not a flaw. Coil weight cannot be more than 50 kg along with a wire. If a coil is composed of a few pieces, a length of every piece must not be less than 10 m.
Mechanical characteristics of titanium wire must fully comply with requirements specified in a table.

Every coil with wire must have an attached to it mark that will define:

— number of batch and smelting;

— inspection stamp;

— release date;

— name of manufacturer and trade mark:

— index of alloy grade;

— marking of standard.


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. Wrapping of coil is allowed with using synthetic mesh, or plastic film which thickness is 100 — 200 µm without paper pre-packaging according to GOST 10 354−82. Wire that is rolled into coil must be joined with natural or synthetic binder according to requirements of standard technical documents.


without limits
welding is done without further heat treating or 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
