I am in the process of purchasing a commercial quenchant and am curious about the DT-48 quenchant from Maxim Oil. I have found some info on this stuff from 2011 on KD FORUMS website. Does anyone here have any info on the product/use it? The difference in price between Parks #50 and DT-48 from Maxim Oil is only $21.11 per 5gal. It isn't so much the price that I have a problem with, I like the idea of buying a product that Maxim is producing. But if it doesn't do the job, that is a problem! Any current info on this product would be helpful. Hopefully I haven't missed this discussion somewhere on here that was more recent. If I did I apologize. I will be heat treating 1095 from Aldo.
