Tu 48-19-290-91. Molybdenum wire type Sprabod.
Are you interested in TU 48−19−290−91 «Molybdenum wire of Sprabond type» from the supplier company AvecGlob? Here you will find interesting information on this topic /
Application area
Sprabond wire is the licensed name of the molybdenum wire produced by the company «Plansee», Austria, which is intended for the purpose of flame spraying. The permissible temperature of use of the material is 320 0 С, the maximum hardness is 62… 65 HRC.
These specifications establish the requirements for MF molybdenum in relation to the processes of spraying piston rings of diesel engines.
These technical conditions apply to dimensional sheet blanks, which are made of molybdenum of MCH and MCHVP grades, and are designed for manufacturing large-sized structures used in electrothermal production and other industries.
Technical requirements
The chemical composition of the wire must meet the requirements specified in the table:
| Mass fraction,% | |||||||
| Detected impurities, not more than | Molybdenum | ||||||
| aluminum | iron | nickel | silicon | Calcium and magnesium (in total) | carbon | oxygen | |
| 0.004 | 0.010 | 0.005 | 0,0010 | 0.005 | 0.005 | 0.008 | the basis |
Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer a molybdenum wire of the Sprabond type, which meets the technical requirements of TU 48−19−290−91. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Assortment and mechanical characteristics
The dimensions of the wire and the internal diameter of the coil must meet the requirements specified in the table.
| Diameter, mm | Length, m | Inside diameter of the bay, mm | |
| Nomine. | Prev off | ||
| 3.17 | ± 0.05 | from 4 to 20 inclusive. | 560 ± 40 |
The surface of the wire should be free from cracks and laminations obtained during plastic deformation. Impressions, rolling captivity, traces of abrasive stripping that do not lead to wire diameters beyond acceptable tolerances are not a sign of marriage.
The temporary resistance in the tensile test of the wire should not be less than 735.5 MPa. Relative elongation is not regulated by GOST.
