Specifications Tu 11-90 (Yaye0.021.055 TU)

1.1 Strips shall comply with the requirements of these specifications.

1.2 Parameters of strips depend on chemical composition, delivery condition.

Molybdenum grades	Group	Delivery condition	Thickness ranges, mm	Recommended application
MF	А	not annealed	0,05 - 3,50	Main parts of electronic devices
MS	В	annealed	0,10 - 0,30
MRN	А	not annealed	0,10 - 3,50	Auxiliary parts and accessories

Depending on the method and direction of rolling:
- Cold-rolled 0.05 - 0.60 mm. thickness, rolled in one (P1) or in two mutually perpendicular directions (P2);
- hot-rolled 0.70 - 3.50 mm thick, rolled in one direction, with the calibration of 0.70 - 2.00 mm thick strips by cold rolling.

1.3 Chemical composition of strips.

Tensile strength, MPa (^kgf/mm2) at least

d5 - Tensile elongation at break (%)

1.11 - Molybdenum strips should be flat. 0,05 - 0,20 mm thick strips may have a slight waviness, which disappears when rolled into a cylinder of diameter 50 - 60 mm.
Ultimate deviations from straightness of strips with thickness over 0,20 mm shall not be more than
- sickle-shape - 2 mm. on the segment of the length of 300 mm;
- Shortness on the piece with the length of 100 mm:
along the strip - 3 mm;
across the strip - 2 mm.
