4140/4150 that's exactly what's been suggested (not by the supplier but the contractor who's in charge of making the roll) won't give the required hardness after induction. According to my experience the maximum achievable hardness would be 45 HRC (we need 62-65 HRC)...
Hey there. We've got a straightener roll that shall be made from 6150 steel. As the required stock isn't available for now in local market, we've considered changing it to 52100. As you may see in the attached drawing the drum ought to be hardened and tempered to be as strong as at least 1000...
Hello.
As you know there are two main methods to control gears after production, over pin and gear span measurement. I checked these two on a gear produced in our workshop. The Wk for three gears was OK but over pin had the unconformity in the scale of 0.5 mm! Where is the problem? What do you...
