S7 for a blade?

Anyone ever try to make a blade out of S7? I've looked at the specs for it and it gets hard enough and has the strength. Probably be hard to heat treat properly.....anyway I got about 30 feet of 1" round sitting around and was thinking of trying a blade with it. Any input would be helpful

s7 is a air hardening steel

good shock but will be hard to move under the hammer hi moly content

preheat about 1250 raise to1700 to 2050 anneal immedialety by heating to forging temp them placingng in a hot box

so sez jim hrisoulas

this type of steel may work better as a stock removal type

S7 is a good steel to make tools out of for use by blacksmiths. It is shock resistant and will stand up well to being hammered on and as Mike pointed out it is air hardening. It is not likely that you will draw the temper too much using this stuff on hot steel. I would save this stuff and use it to make tools that need to stand up to a lot of heat: punches, drifts, hot cuts, etc.

 

Have you looked at the spec. sheet for S5? I have not ever used any but, it looks like it would be a great steel for swords. You ought to be able to put a sword forged of S5 into service with a hardness of 58 on the Rockwell C scale. Unfortunately, it seems to be rather pricey.

Thanks guys I actually tried to move this stuff with a hammer a long time ago and it was way too tough. Got a 35 ton Press now :D I'll be using some of this stuff for dies for the press. Might try to get some flat enough with the press for stock removal. I've seen dies made from this stuff cut through 1/4" steel plate cold and still be sharp enough to cut you if you touched it wrong. I'll probably wait a while until I'm a bit more experienced before I play with it though....Again thank you for your input

If you want to make a blade out of S7, consider something chop-y and cleave-y, like thick, heavy seax or a meat cleaver.

I had a strange thought the other day.

If I were locked in a room with a copy of myself, i wouldn't like me very much.

I have blanks of S7 done , I use a mill and mill a round to the thickness I want

that gives Me a nice conture on the spine too, I'v had trouble with forging the air harding stuff so I stick to stock removal for the air harding stuff(on another note I oil quench 440C)

tolls are always a good way to go, can a Bladesmith ever have to many???
