MilwaukeeJon Posted December 2, 2019 Share Posted December 2, 2019 I've got a nice cylindrical steel kitchen trash can with a galvanized removable insert. Was thinking that it might be a nice large quench tank. Can one safely oil quench (canola) in a galvanized container or would that be problematic?

ThomasPowers Posted December 2, 2019 Share Posted December 2, 2019 No problem; the oil will be burning before you have temps where the galvanization will be an issue. Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 2, 2019 Share Posted December 2, 2019 That's no problem Jon, galvy/zinc has to be heated into the low orange to give off significant zinc oxide fumes and if your quench oil hits more than maybe 600f. putting the raging fire out will be a greater concern. Something with a lid you can put on it quickly is a really good idea. Never, NEVER, NEVER try to put an oil fire out with water !!! Smother it, or dry chem or CO2 extinguishers only. My quench tank is a 15 gal. grease barrel with lid in a cut down 55 gal. drum with lid. I cut and dropped a piece of 14 ga steel in the 15 gal barrel to prevent punching holes in the thin barrel, the outer drum is containment if I get a boil over or fire. One lid on the quench barrel and another on the 55 gal containment drum, shut off the forge and leave the shop till the smoke clears. This is the scary time, the oil smoke is flammable and there is a HOT propane forge sitting too darned close for comfort. Even with the burner shut off the forge itself is HOT. Ah HAH, we're online at the same time again. Good morning Thomas. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 2, 2019 Share Posted December 2, 2019 Can I throw in another NEVER! (Don't even try it for fun---unless you are really really into pain and don't mind permanent disfigurement!) Quote Link to comment Share on other sites More sharing options...
MilwaukeeJon Posted December 2, 2019 Author Share Posted December 2, 2019 Many thanks indeed! For general 5160/1075/1084 quenching, do you all think that canola is good or should I be using something else? And do you always preheat the oil to 130 or so? I have generally done this as a routine matter when quenching these steels. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted December 2, 2019 Share Posted December 2, 2019 why not get a real quench oil? Quote Link to comment Share on other sites More sharing options...
MilwaukeeJon Posted December 3, 2019 Author Share Posted December 3, 2019 Which one for these steels? I don't want anything too fast right? Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted December 3, 2019 Share Posted December 3, 2019 I use McMaster Carr 11 second oil, the pinned post covers most of it here https://www.iforgeiron.com/topic/33919-oil-quench-what-type-to-use/ Quote Link to comment Share on other sites More sharing options...
