Hello,
We have a job that requires ANSI Y.14.5M – 1982 tolerances however, we currently do not have that standard in house. What is the tolerances on 1,2, and 3 decimal dimensions?
Thanks!
Hi Guys!
I am trying to have a nice finish with dry lube spray on some parts however the dry lube does not stick on the parts or they come out pretty easy. Is there anything I can do ?
Thanks!
Hi guys!
We are case-hardening 1018 steels here at work (0.003"-0.005" Deep). I was just curious what would be the HRC value when we test those parts within 0.003-0.005" with Vickers? We are finding them 30-35HRC lately. Do you guys think they are soft? What would be the min-max HRC value for...
Hi Guys!
I am working on a project and I am asked to heat treat 17-4 PH steel(AMS 5643) to H1025. What would be the best way to heat treat such a material ?
Thank you!
Hi Guys!
I was just curious about how to reduce the dew point in the furnace... Endothermic generator's dew point is as we want. but whenever we checked the furnace dew point, it shows 70 when it's supposed to be 55. We first figured there is water in the endo gas pipes for some reason, even...
Hi Guys,
I am currently having some problem in our endothermic gas furnace for oil quench. The parts do not get HRC 50-52 Hardness. They stay at HRC 45 after quench usually.
We have Nitrogen, Endothermic gas and natural gas for the atmosphere of the furnace. Nitrogen kicks in when we put the...
Hi Guys!
We temper our parts after oil quenching. The furnace that tempering happens in provides a lot of smoke once the operator opens the door. The hole building gets all cloudy all day and the smoke&smell give the other operators headache.
Does anybody know what might cause that and how I...
Hi Guys!
I am currently doing heat treatment of cylindrical shape-1144 Steel. I am trying to harden them from RC40-45 to RC50-52. I set up the furnace on 1575 degrees. Based on the smallest cross section, soak time is about an hour. The outcome is always harder than we expect (around 60ish)...
