Steel is a common durable alloy, and while most steel used in tools is already tough, you can harden it even more to prevent wear and tear. I can often quench harden the working end of something, polish it up quick and let It's like a partial temper, to get the stresses under control until the real tempering. O1 高温焼きなまし処理をした後、徐冷したものをいいます。 O2 超塑性加工をして、溶体化処理させる等の特別な加工熱処理を行なったものを言います。 O3 偏析を減らしたり、むらをなくしたりするために高温で均質化処理したものをいい H The correct time to temper steel for a knife is after the blade has been formed and shaped but before the final assembly and polishing. Tempering at higher temperatures results in a softer blade that will be more durable and less likely to snap off, but will not hold an edge as well.

For most applications a tempering temperature of 400-450ºF is employed. Typical temper colors for carbon steel are straw (220 C), brown (240 C), purple (260 C), dark blue (300 C), and light gray (330 –350 C). Annealing involves heating steel to a specified temperature and then cooling at a very slow and controlled rate, whereas tempering involves heating the metal to a precise temperature below the critical point, and is often done in air, vacuum or inert … Hardened steel prevents knife blades from dulling and The δ-phase, not shown on this dia-gram, exists from 11 Aluminum alloy temper designations are described in terms of heat treating, strain hardening, aging, etc. The golden straw color you see in the picture below is the sign of a proper heat treat. I temper my O1 around 64-66rc, so won't guess your blade hardness in 400+F range. The same temper colors appear on alloy (especially highalloy) steels at higher temperatures Baring any contaminants on the steel, temper colors are accurate. O1 Tool Steel O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance. The difference between annealing and tempering comes down to how it is treated. Hardening steel with motor oil is a way of performing what is called the case hardening of steel. Certain components need elements with particular properties. In short, bring it to critical temperature, quench it in vegetable oil, then temper it in an toaster oven or regular kitchen oven for one hour at 400˚. Then I polish them up quick with very fine wet-or-dry sandpaper and put them back in my furnace for tempering by colors. Metals are used in manufacturing items such as an ordinary saucepan to space-going vessels. 2/Practical Nitriding and Ferritic Nitrocarburizing Iron-nitrogen equilibrium diagram. O1 steel has been used in knives for decades. I leave the furnace door We have made thousands of tools over the last 30 years and as you can imagine, students are not always precise in their judgement of temperature. that shouldn't really happen at knife cross sections with O1 though. it should have plenty of hardenability to spare. In your case, if it PDF FILE - CLICK HERE FOR PRINTABLE WORKSHEET Steel can be treated by intense heat to give it different properties of hardness and softness.
