So after the threads a while back about Aldos W2, and now that i have a hardness tester I ran some coupons on the W2 I had. Somewhere around 20 bars of 1, 1.25 and 1.5" that Ive bought over the last few years. I hadnt really used any of it before. My initial coupons were all in the 30-40hrc range. Talked to NJSB who passed me off to their expert. Followed his HT that he wanted (1750, 1550 cycle, then austenize and quench in P50). Still got same HRC. They said they would replace half of what i have, 10bars of the 20, because some were bought 3-4years ago. So, since im going to be stuck with 10 bars, i decided to test them all before sending back any that might be good. I think 5 hardened to about 60 when i think they should be closer to 65. I did a 15 mins soak 1750, 15 at 1550, 1500 to quench in P50.
Also, i verified my kiln temp with 1500*tempilaq. Verified tester with a 64hrc test block. On top of that, I put in 2 coupons each of 1084 (low 60s), 1095 (65ea), and 80CRV2(62 ea). This tells me that the problem is the steel, not my HT unless theres something Im doing wrong.
