heat treatment oil
heat treatment oil
(OP)
Hello,
Im currently machining some model racing engine crankshafts out of 9310 (en36A)
I wont need to carburise or nitride the first few but will want to heat treat to increase the properties.
I have the heat treat specs for this alloy, but am after info on the best 'oil' to quench. Im hoping a gas fired oven is also acceptable for heating as i have one already. ( used for Investment casting).

My big concern is scaling of the surface. You don't have to worry about decarburization much with the 9310, but in an open atmosphere, you will scale up. Plan of finish machining after heat treatment.

Quenching oil is a special oil with a sole purpose then? No common engine/trans fluids are appropriate? Air cooling could be possible as the parts are approx 65mm long, 6mm dia for 25mm, 12mm dia for 35 and 25m Dia remaining. Bored to 8mm Dia for 35mm. Parts wil be finished ground for final sizing as fit is critical.
