These flat products belong to the most common commercial semi-finished products. A convenient form factor, a huge variety of available sizes, special Nb properties and lower cost if compared with tantalum make the considered products highly-demanded in high-tech industries.

Metotechnics Company sells niobium sheets and flat bars. The products can be ordered by phone, via e-mail or on the Prices page on our website.

See the corresponding sections of this page for the production methods, grades and application recommendations.

Grades

Flat bars are made of RN-8 and SB-1 alloys. These materials contain not only niobium, but also some alloying agents. RN-8 is based on niobium (Nb). Tungsten (W) - 8.0±1.5% and zirconium (Zr) - 2.5±1.5% serve as alloying agents. Tantalum (Ta) - 0.4%; iron (Fe) - 0,10%; titanium (Ti) - 0.10%are the most significant admixtures. SB-1 is also based on niobium (Nb). Zirconium (Zr) - 0.8-1.3% serves as the alloying agent that improves the alloy properties. Tungsten (W) belongs to admixtures; percentage of tungsten and molybdenum (Mo) is 0.1%; tantalum (Ta) is another significant admixture (0.4%).

Sheets are produced of pure niobium (Nb) with weight per cent 99.8%. The admixture percentage is low if compared with alloys used for making niobium flat bars. Tantalum (Ta) is the most significant admixture (0.1%), the content of other chemical elements is basic points and thousandths of percent.

The chemical composition of considered materials is regulated by TC 11-75 Яе0.021.022 and TC 48-4-337-75 for flat bars and TC 48-19-284-78 and TC 48-19-513-91 standards for sheets. In compliance with these standards, niobium and its alloys should be produced with help of vacuum melting.

Production

Niobium sheets and flat bars are made of cast ingots by a multi-stage technological process. The blanks are pressurized on the first stage for making them plastic enough. This operation should be heated to 1400-1500 °С in a neutral atmosphere (inert gas or vacuum) for reducing the material gasing and oxidation. Then hot forging is performed for making the blank thinner. This operation is performed after heating to 1100-1500 °С in inert gas and vacuum. Flat bars and sheets are ready for supply after cold rolling. Thermal processing of blanks (annealing) is made after each stage.

Niobium flat bars are 0.1-10 mm, 50-250 mm wide and at least 50 mm long. Niobium sheets are thicker (0.1-30 mm), are 50-500 mm wide and are much longer (their length can reach 1200 mm). Thin and long products are supplied in rolls, thicker products are supplied in packs.

Niobium sheets and flat bars (sizes, extreme tolerances, supply condition, mechanical conditions) should comply with the requirements of several standards - TC 48-19-284-78 and TC 48-19-513-91 (sheets) and TC 11-75 Яе0.021.022 and TC 48-4-337-75 (flat bars).

Application

The main application of the considered products is constructional materials in devices, installations and other equipment working under high temperatures, in aggressive atmospheres or under other conditions that require special properties. First of all, these are chemical engineering, nuclear energetics and metallurgy.

Among certain applications of niobium sheets and flat bars, pump components, protective covers of reactor uranium fuel elements.
