| Abstract: | | 1. |
Forming tools operating under conditions of the constant presence of an abrasivepowder mixture, contact pressures in the range 1.3–1.8 kN/mm2, and low angular velocity (0.5–0.8 rps) can be made of structural steel 45 instead of high alloy tool steels.
| | 2. |
The service properties of forming tools made of structural steel 45 are determined by the carbon content and by the parameters of cyclic heat treatment with the use of induction heating.
| | 3. |
The maximal life of forming tools made of structural steel 45, subjected to cyclic surface hardening, is 0.9·107 cycles under conditions of continuous stepped rolling of filled electrode strips.
