I have some forgings that need to be heat treated to the following properties:
Hardness [HBN] 223-255
Tensile strength [ksi] 121 min
Yield strength [ksi] 100 min
Percentage elongation 20 min
Percentage reduction in area 60 min
Charpy impact [Ft lbs] 23 min
I have checked the ht ASM handbook...
Hi,
I am new at my job and in charge of the quench oil. We got it tested this spring and it looks like it is at the end of its life. We have 2500 gallons total. The last time all of the oil was replaced was in 2006 and it was reconditioned in 2009. I am looking for advice on what to do. Can this...
I have some parts that are being machined and there is more vibration than usual. Usually there is less than .015" of movement and with the current batch there is more than .05" of movement. I looked at the heat treat charts and mechanical property results and nothing looks out of the ordinary...
I was wondering if anyone knows how high 17-4 material can be heated during solution without growing grain size. I know the recommended temp is 1900F but I'm wondering what will happen if the furnace is hotter(~1970F).
Thanks
