steel hardness b-4 heat treat

[manassas dragon]

bought some s-35 from aldo and it's harder than a woodpecker's lips. anybody know what the approximate hardness is for pre-heated steel such as s-35,1095,etc. wondering how good a knife can be made w/o heat treat by you guys.

s-35 ?? Do you mean S35VN from Crucible ? It should be spheroidize annealed .Ask Aldo. 1095 should also be purchased as spheroidize annealed.

Yeah Mete, I've never heard of s-35 either. Maybe Aldo's got some new top secret stuff.

you guys never pass up an opportunity to bust somebody's chops. yes,i meant s-35 vn. so approximately how hard is it? excuse me for being ignorant on the subject. maybe someday i'll get there.

...so approximately how hard is it? QUOTE]

Hard enough to bust those wood pecker's lips, but worthless as a knife until hardened and then tempered.

Are you talking about the "mill scale" on top of the steel, or the bare steel itself?

Mill-scale is a bitch to deal with, it will eat up belts and bits like crazy; pickling your barstock overnight in regular vinegar helps loosen it. Paying extra for precision-ground/surface ground stock is always worthwhile if you're a stock-removal maker.

I would be surprised if the steel itself isn't coming to you fully annealed; both Crucible and Aldo have excellent reputations for delivering good stuff.

wondering how good a knife can be made w/o heat treat by you guys.

Without proper HT? You may as well make it from low-carbon "welding" steel from Lowe's and save a few bucks. It will be junk either way.
