So, I quenched W2 in oil yesterday and it looks like the oil was too slow for the steel, so now I am thinking about trying to quench it in brine. For those of you familiar with the subject, can you confirm or refute the following?
- W2 hardens 1/8 deep, so no pregrinding is necessary on thin stock like 5/32 sheet.
- Heating brine will slow quench speed and be gentler on the steel approaching oil quench in effect
- Brine should be kept at room temperature vs heating it up
- Blade has be quenched egde first (as opposed to tip first)
- One should do interrupted quench, 3 sec in, 2sec out repeatedly until blade is cooled
- Brine quench forms a crisper hamon
- Brine quench is not worth the risk (of loosing the blade)
- Brine is best in 10-12% brine solution.
I would consider getting Park 50 if it wasn't so damn hard to obtain. I also like to use a bit more than 5 gallons of it, so I would need to buy 2x5gal buckets. I would like to give brine a try before taking a plunge.
Thanks in advance.
