Default Need refresher on tempering to harden please

Need a refresher on tempering to harden, please more of the need of hardening for stiffness

Ok so I needed to make a sort of a tool out of another tool and I heated the area of it I wanted to harden.

heated to a high red-orange and them dropped it into a huge water bucket but I did not get the results I was looking for.. "hardened with no flex or bending"... I tried to pry with it, and it still bends like soft steel what is it a am doing wrong having too many brain farts to think this out clearly...

Thanks

I used one of those cheap automotive door panel tools you pop door panels off with see pic below.

I needed to bend it to a hook and then intended to harden it so it would act as a pry bar in a way...

because it fits perfectly around the valve guide to pry up and off the guide seals that are stubbornly stuck to the guides.

I was going to try to use the one in the top part of the pic but that seal puller is just too large to get into the spot needed. so, I used the door panel tool under in bottom of the pic.

Chances are that it’s mild steel and doesn’t have enough carbon to harden it.

I have always used channellocks to pry the old seals out. With a bit of wiggling they usually pop right out.

I’m bored so here is a shot of the way I do them. Grab the seal and gently pry it up using the head as a fulcrum.

Randall, your looking in the wrong aisle of the hardware store. Look for a Catspaw pry bar in the carpounder section. Might have to do a little regrinding/massage on the claw. But, I think you will have what you need.https://www.bhg.com/shop/vaughan-and...f81f13631.html

Zach, What tool are you using to install the valve seals I borrowed one from a friend I m assuming from Summit... I have the Valve seal removal pliers but they ain't worth a shit...

So I think when I get the chance I'll just mill out my own design of removal and install tool just need o pick up some material but for ow using the cat's paw worked out much better.
