I'm not qualified to answer your question, tecnovist, but be patient, somebody will come along here soon. I believe that files are usually 1095. As for tempering, I don't know why you would want to temper vice jaws, I would think you would want to leave them tough.

Hardening the jaws makes them very hard but very brittle as well. By putting the jaws in the oven for 2 or 3 hours you remove some of the hardness and this makes your jaws less brittle. If you don't do this tempering you risk the jaws breaking at a later date. Files are made from W-1 or W-2. Beware though there are junk files made in China that are surface hardened only. If you use those they won't harden. 1095 is actually classed as a spring steel, even though it has a high carbon level aproaching 1 percent. I use it mixed with 203-E nickel alloy to make my Damascus steel.. |

I would anneal the jaws and not harden them at all I have a vise that I have used for about 50 years now and it has marks from the files and hack saws and grinders. If the jaws were hardened I would have put unecessary wear on the files and hack saws....

new files you buy at the hardware stores and such are usually 1095, industrial quality files that you can special order are 10105 as are the files from yesteryear. they are commonly referred to as 95 point files and 105 point files. I learned this from a seminar put on by one of the suppliers at a Blacksmith Convention years ago.

Just turn the oven up to 375 or 400 and you should be fine. Put the jaws in there for a few hours and then either let them cool or put them in water. I just checked and most files are 1095 which could be why they make good knives. I'm glad you fellows pointed that out it gives me another source for that steel. |

Conan_568 ----Hi--- by the looks you mean celsius -- and not Fahrenheit i found this site, tells you a bit but is not ease to follow---IT dos not tell you the hardness that is achieved--- MatWeb - Online Material Data Sheet 5 AISI 1095 Steel, oil quenched from 800°C (1475°F), tempered at 480°C (900°F) 6 AISI 1095 Steel, oil quenched from 800°C (1475°F), tempered at 540°C (1000°F) 7 AISI 1095 Steel, oil quenched from 800°C (1475°F), 595°C (1100°F) temper Hi -- Rich Hale ---If the jaws were hardened I would have put unecessary wear on the files and hack saws.... Thanks --- thats a good point ------ what a i should be arming for is a hard ness a bit lower than 400 hockwell --- ok maybe its 40 rockwell ----
