Re Nail Hardening

Hi Brett ,


Nails Are Mild Steel,you Could Try A Ramset Pin Which You Could Anneal Then Reharden, The Shank Of A Drill Can Be Annealed Then Redardened.

If You Get Stuck Give Me Your Email Address And We Can Sort It Out.


Regards Daniel Didtas.

I think most nails are mild steel. Here is a quote from a link about nails "Besides mild steel, nails are available in types 304 and 316 stainless steel." Aren't the nails you drive into cement harder though?

Why not just use drill rod or something similar?

Nauls for concrete are hardened ,though I don't know what alloy. For a standard nail could be case hardened for such a tool using a case hardening powder like Kasenit .

Try a highly concentrated solution of Red Devil Lye and water.

Caution: it is highly corrosive to human eyes and hide.

Cut masonry nails are indeed hard. I'm made lots of small turning tools just by grinding them to shape, being careful not to draw the temper. No idea what the steel is - so I couldn't guess at the HT recipe - but just grinding the nails to shape they take and hold a nice edge.

Or get some O-1 or W-1 drill rod. Drill rod the diameter of a nail would be real cheap, and you'd have a known alloy that HTs well.

Try ToolandDie.com, they have tool steel at a good price and their shipping is quick. Their W1 starts out at 1/16 in three foot lengths. I just got in some to use in making a welded "cable" bar with.

thanks for all your help guys. i thought they were mild but i thought it cant hurt to ask.
I was considering buying drill rod but i cant be bothered waiting for it to ship here, i might see if the $2 shop sellssome cheap drillbits i could use, or maybe i will try out of some flat 1095 i have.
thanks guys,
brett

The square cut masonary nails are hi-carb. They respond well to the same heat treatment used on 1095. Give the same spark at high hard as 1095. I've made a lot of small wood chisels and gouges out of them.
The rods used to hold concrete forms together are also hi-carb. Respond well to 1084 HT practices. These are the ones with the loops on the ends and the small plastic cones on them, about 1/4" in diameter.
Nicholson chainsaw files are also good hi-carb source in small diameters.
Reinforcing banding used in prestressed concrete water lines 48" and larger are hi-carb. Just tough to come by.

Piano wire from ace will work. Scrap wise, Any "Spring" will work. Bed, couch, car seat, carhood ,Garage door spring. What about an old file tang? Looks just like a cut nail. I made some fids and leather working tools out of the springs from an old VW seat. I used the push rods out of the engine for the handle.
