Straight into 2065F with 30min soak, plate quench and some 360F tempering will get me 62.2-62.4 every time even without any freeze treatment.
Tempering Temperature F. Stress Relieving Annealed Material: Heat to 1200/1250F, hold two hours, cool in still air. Hardened Material: Heat to 25F below original tempering temperature, hold two hours, cool in still air. Welding Use type 440C or 420 filler material. Annealed Material: Preheat to 600/800F. Maintain above 600F during welding.
Heat treatment is the process of heating and cooling metals to change their microstructure and to bring out the physical and mechanical characteristics that make metals more desirable. The temperatures metals are heated to, and the rate of cooling after heat treatment can significantly change metal's properties.
Heat treatment is a process of using high temperatures to change the molecular structure of the material in order to harden or soften the material. The process of heat treating is a complicated one if you are hoping to achieve high standards of quality. For the home shop hobbyist, the process is simpler, to an extent.
Heat treatment of steels is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.
Heat treating (or heat treatment) is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or q390c heat treatment
Heat Treatment Annealing Normalising Hardening Quenching medium Tempering 850C 850 920C 850 860C Oil 450 650C Hardening Heat components slowly to 850C, hold until uniform then quench vigorously in oil (or polymer with an equivalent quench rate) to between 80 and 110C. Tempering While still warm, re-heat to 450
For heat treating I experimented and combined my experiment from the six different ways of heat treating Bhler describes. (Oil hardening 1070 C without subzero treatment, 1150C with subzero treatment, 1150C without subzero treatment.
Heat Treatment of 300M Alloy. 300M must be normalized at 927C (1700F) before hardening. After the normalizing treatment, the alloy is hardened by heating to 871C (1600F) and oil quenching. After hardening the material is double tempered for 2 hours at 302C (575F) and 2 hours at 302C (575F) air cool.
The thickness we use in knives will come up to heat very quickly. A very thin hollow ground blade will take less time than a large flat or convex ground chopper. As little as 10 minutes can work just fine for a thin hunter. 15 us usually just fine for a larger Bowie type blade.

2004. A. It may be possible to heat treat your article to RH950 or CH900, depending on exactly what you have. CH900 applies to 17-7 PH (Type 631) wire that has been previously solution annealed and then cold drawn, which is then aged for 1 hour at 900 F (482 C).
Place the blank, the unfinished piece that will become your knife blade, in the heat treating oven and heat slowly to between 1,550 and 1,650 degrees Fahrenheit to anneal it. This process removes any prior heat treatment and makes the metal soft enough to grind or otherwise shape. Do not heat faster than 400 degrees per hour.
