Thank you, I use a torch connected to a propane gas cylinder, which I graduate the force of the flame in the rotating knob of the nozzle, I bring it closer to the piece in such a way that it gives me the tempering temperature of approximately 850 degrees Celsius. Then I pass it to the tempering medium, (Vegetable oil), which I introduce quickly to achieve the tempering. After this, I carry out the tempering process, in an oven at 400 degrees Celsius, and leave it at that temperature for two hours. In this way I achieve sufficient hardness to machine hard materials such as iron or steel. Thanks and regards

Thank you

Хорошее соотношение цены и качества, но будет использоваться для обработки мягких металлов и низкоуглеродистых сталей и прослужит долго.
