1095 vs 01 tool steel

[jackie]

can i harden o1 tool steel just like 1095. which is heat to non-magnetic  then quench in 150degree quenching oil then heat in a 400 degree oven for two hours.  is 01 tool steel a litte more rust resistant than 1095 thankyou  jackie

The procedure you described would be more suited to O1 than 1095.
You already have it figured out.

O1 has more chromium, so may resist corrosion a LITTLE BIT more, but both need to be watched after.

I've only used 1095.I'm gonna try 01 TOOL STEEL.I only got a simple brick forge.I LEARN STUFF HERE EVER DAY,THANKS ANDERSEN FORGE.

Karl, why do you say that is more suitable for O1?

1095 requires and fast quench, where as O1 will require a Med. speed quenching oil.  Also in order to get the best proformance from O1 you need to soak at temperture (10 minutes), this is also required with 1095, but less time.

This very well could be a dumb question but I figure if I ask then maybe I'll get less dumb...  Where would a guy get information like this on several of the steels commonly used for knives?  It seems like most have some particulars (soak times at specific temps, etc.) that vary, and sometimes a great deal.  Is there a book, chart, or site that lists the info or is it what you've learned over the years?  Thanks.

Perfect explanation.

More like a combination of both the scenarios you mention.
It's like slowly gathering this info and then utilizing it until one can make sense of it.
That's why it behooves a maker to pick ONE steel and learn it WELL, such as its forging and hardening procedures, proper quenchants, austenizing steps, post forging and annealing sequences, tempering, etc. possibly creating a small data base of this info, and THEN moving on to another steel.
For performance reasons only, I could use 5160 and never use another steel and be semi-happy.
Learning a whole bunch of steels is just plain fun!

That's a great bit of advice Karl.  I should probably listen to it .... .  That would also help solve a monetary problem of investing in multiple quenchants for the time being.
