|Heat treatment.||The annealing of billets used long-term in order to reduce the residual magnetic induction in the magnetic circuit of the electromagnets, thus providing a magnetic quality steel 12X17 when the residual induction of the magnetic RF Of 0.3 Tesla. HC — coercive silurana 0,23 ka/m; Nm 20 ka, the maximum saturation induction Bs is 1.6 T. In the magnetic circuit of the electromagnets to reduce the magnetic induction and residual needs of the workpiece (part) to be subjected to long term annealing. To obtain the hardness and mechanical properties installed at ST CKBA 010, and also to achieve corrosion resistance to the maximum, billet fittings (details) should be subjected to annealing. Welded assemblies and other products 12X17, subjected for increasing corrosion resistance to annealing under such regimes as heating up to temp.775−800 °C and matured for 2−3 h In cases of the absence of any requirements to the durability of microcalli. corrosion — air cooling; heating to temperature. 780−820 °C, With requirements for durability microcalli. corrosion — air cooling, exposure — 8 hours.|
