|Oxide of yttrium||From 1.5 to 2.3|
|Tungsten, not less||97.623|
The size of the rod and limit deviations
|Nominal diameter, mm||Limit deviations of the diameter, mm||Length, mm|
|From 2.00 through to 6.00 to 1.0||± 0,07||120|
According to the 48−19−221−83 rod with a diameter of 10.0 mm comes brushed. On the surface not allowed traces of graphite grease, remains of scale, burrs, grinding cracks and risks. Scratches and fingerprints, not deducing the diameter of the rods beyond the permitted tolerances, the rejection characteristics are not. From the ends allowed burrs and traces and traces of the oxide film on the surface. Bars should not have internal delaminations and cracks.
According to the 48−19−221−83 bars must be straight. The deviation from straightness of bars with diameter from 2.0 mm to 6.0 mm should not be more than 0.1 mm on the length of the rod 120 mm, and for rods with a diameter of 8.0 mm and 10.0 mm — not more than 1 mm on a length of 200 mm.
