plain ol Bill Posted September 17, 2012 Share Posted September 17, 2012 I am making some parts from A36 that are riveted together and using super quench trying to hardIT a little. My question: Since it has a lot of salt in it am I going to run into a corrosion problem later? - How are any other users of this cleaning up your parts? Thanks for any help folks -- Bill Quote Link to comment Share on other sites More sharing options...
george m. Posted September 17, 2012 Share Posted September 17, 2012 I just rinse the object in my slack tub. No problems so far. GM Quote Link to comment Share on other sites More sharing options...
Richard Furrer Posted September 17, 2012 Share Posted September 17, 2012 Cover the mixture so the salt does not permeate the shop. I had 50 gallons mixed up and sitting in the shop years ago...rusted everything till I got a good lid. Rinsing the work dunked in it was easy.

Private Entrance Posted September 17, 2012 Share Posted September 17, 2012 Ditto on the rusting issues. Took me a week to figure out why everything in the garage was turning brown with rust. Got a bucket with a lid and the problem was solved. Quote Link to comment Share on other sites More sharing options...
HWHII Posted September 17, 2012 Share Posted September 17, 2012 The first time i used it, even after rinsing I have had a bit corrosion problem. I sprayed it with WD40 while warm and no more problems. Quote Link to comment Share on other sites More sharing options...
Jack Evers Posted September 18, 2012 Share Posted September 18, 2012 I made some hooks to support heavy pipe, they weren't strong enough so I hardened them. May not have even rinsed them and a year later no problems. I did leave a pretty heavy scale since they were in a corral where appearance didn't matter. They are outside in a very dry climate. Humidity rarely above 20% in the summer. I store mine in a plastic bucket with a tight lid. Quote Link to comment Share on other sites More sharing options...
Crunch Posted September 19, 2012 Share Posted September 19, 2012 Will A36 harden? I thought A36 was mild steel that wouldn't harden... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 19, 2012 Share Posted September 19, 2012 A36 often has an appreciable carbon content. Use of a "very fast quenchant indeed!" will give it *some* hardness. It will not be hard like a medium or high carbon steel will get but it will be harder than it was. The higher the carbon content of the A36 the harder it will get. I still have the chisel that Robb Gunter cut off a stick of A36 and forged and quenched in the old school version of SQ and then used to cut the original piece with out deforming the quenched edge of the chisel!

thingmaker3 Posted September 21, 2012 Share Posted September 21, 2012 All steel will harden. The question is "how much?" Quote Link to comment Share on other sites More sharing options...
