– Work hardening
Thanks to work hardening, there is a considerable increase in strength (Figure 6.7) which,
in combination with the plate-finished surface, means mechanical wear is lessened.
– Material savings
The material savings with rolled threads, compared to machined threads, is about 20%.
– Short production times
Rolling times are very short compared to the production of threads by machining (see Tables
6.1 and 6.2).
– Nearly all the main materials used in practice can be rolled
Nearly all steels can be rolled, except for free-cutting steels, up to a failure strain of over
8% and a maximum strength of 1200 N/mm2. Soft Ms 58-63 can also be rolled.
