| Features of heat treatment | To obtain characteristic values of mechanical properties and hardness set ST CKBA 010 and to achieve maximum corrosion resistance, parts (workpiece) valves shall be subjected to annealing. To reduce the residual magnetic induction in the magnetic circuit of the electromagnets of the details (blank) should be subjected to high temperature annealing in vacuum. High-temperature annealing in vacuum parts from alloy grade 16X-VI provides obtaining magnetic induction: ≥6000 Gauss in box 1 AB/cm; ≥12000 Gauss in a field of 25 AB/cm; ≥14500 Gauss in a field of 100 aw/cm Before annealing the parts need to be degreased. |
| Machining by cutting | Machining of parts after annealing is not recommended, as it dramatically reduces the magnetic properties of steel 16X-VI. |
