To date, no cold heading wires are available .
Wire for cold heading GOST 5663-79
The increased attention to cold heading processes is due to the fact that cold heading processes are significantly more productive than hot stamping, forging, and turning on a lathe.
These processes ensure the production of products that subsequently require little or no additional finishing operations.
Production of products from wire GOST 5663-79 allows to reduce metal consumption by 30-70%.
Products made from wire for cold heading have high accuracy (4.3 accuracy class), surface finish 8.10 class.
Cold Heading Wire - Raw Material Requirements
Therefore, increased requirements are imposed on the quality of metal for cold heading wire in terms of plastic properties, surface cleanliness, uniformity of properties and structure.
Maintaining the cleanliness of the surface should ensure high-quality packaging of cold heading wire .
Plastic properties, deformability are ensured by selection of the steel grade of wire rod, from which cold heading wire is produced by drawing, and a special production technology.
We supply wire for cold heading manufactured in accordance with GOST 5663-79 .
Wire diameters from 2 to 6 mm.
Cold heading wire is used for the manufacture of fasteners (bolts, screws, nuts, self-tapping screws, etc.) by cold heading.
Qualitative characteristics of wire for cold heading
The quality of the supplied cold heading wire is characterized by the following data:
| Nominal wire diameter for cold heading | normal precision | Increased accuracy |
| from 1 to 3 mm inclusive | -0.06 | -0.04 |
| from 3 to 6 mm | -0.08 | -0.048 |
According to the tensile strength, the wire for cold heading is produced in classes 1 and 2:
- 1 class - 440–580 N / mm 2
- Class 2 - no more than 590 N / mm 2
Cold heading wire is supplied in coils up to 100 kg (inner coil diameter 550 mm).
Before packing, the wire is oiled, packed with moisture-proof paper and polymer film or container cloth.
