Basic properties

Titanium welding wire produced in degassed and etching condition. Its roundness must not exceed tolerances. Its surface must be clean and bright, with no shades of tint, neprotravov or dark spots. Traces broaches, small risks, sunsets deeper than shown in the table.

Note. On a surface of acceptable small diameter wire defects ≤ 3 mm — less than 0.1 mm. When Ø> 3 mm — 0.2 mm. The number of defects exceeding Macrosection depth should be within 10%. Correct defects or surface contaminants by etching the etching is allowed to re-wire coils degassing.

Supply

Presented wire brand VT20−2 St certified. The technical documentation included data on its chemical composition, limiting the percentage of impurities; mechanical properties. We can buy in bulk, any semi-finished products for large-scale productions. We also offer optimal conditions for retail customers. High level of service and efficiency of service are the face of our company.

Wire comes bays with outer diameter up to 900 mm. This wire must not be stuck together turns or bends of more than 100 °. Curl the wire after annealing, is not considered marriage. Coil weight — 50 kg. If the bay is made up of individual parts, the length of each of them must be more than 10 m.

Bay tightly ligated soft titanium wire in 3 places and wrapped in plain paper, and then synthetic cloth or plastic film, thickness 0,1−0,2 mm — 10 according to GOST 354−82 without paper packaging. On top of this bay ligated string of regulatory documents, respectively.

The mechanical characteristics of wire must conform to the requirements specified in the table.
