What is a HT-1 or HT-2 heat treating oven?
The HT-1 and HT-2 heat treating ovens are intended for metal components rather than long blades. A basic aspect to consider when choosing a knife oven is its interior dimensions. Ovens for making knives are considerably smaller than many other kinds of kilns because of the small size of the average project.

What is a vertical furnace?
This is a vertical type of furnace provided with a cylindrical metal retort into which the parts to be heat-treated are suspended either individually, if large enough, or in a container of some sort. The use of a retort permits special gas atmosphere to be employed for carburizing, nitriding, etc.
What is the temperature of steel quenching?
The tempering process consists in heating the steel by various means to a certain temperature and then cooling it. When steel is in a fully hardened condition, its structure consists largely of martensite. On reheating to a temperature of from about 300 to 750°F., a softer and tougher structure known as troostite is formed. If the steel is reheated to a temperature of from 750 to 1290°F, a structure known as a sorbite is formed, which has somewhat less strength than troostite, but much greater ductility.
Is heat treated a specification?
This brief glossary of heat-treating terms has been adopted by the American Foundrymen's Association, the American Society for Metals, the American Society for Testing and the Society of Automotive Engineers. Since it is not intended to be a specification, but is strictly a set of definitions, temperatures have purposely been omitted.
How to anneal hardened steel?
To anneal a hardened metal, you heat it up to the right temperature and then leave it to cool slowly: Since this file steel is close in properties to W1 steel, I used that and heated it up to 1400 degrees before shutting it off and leaving it to cool overnight:
Can knives be heat treated?
Of course, knives are not the only thing that needs heat treating – plane blades and chisels or other tools can also benefit greatly from precise hardening. I’m making the outer case of the oven from 18 gauge sheet metal salvaged from doors that I cut windows into, back while doing my old day job.
What is heat treatment?
Heat treatment is a heating and then cooling process using predefined methods to achieve desired mechanical properties like hardness , ductility, toughness, strength, etc. It is the combination of thermal, industrial, and metalworking processes to alter the mechanical properties and chemical properties of metals.
What is the first step in heat treatment?
The first step in the heat treatment process is heating the metal. The temperature depends on the types of metal and the technique used. Sometimes you need to heat the outer surfaces of the metal, and sometimes you need to heat the whole body. That depends on what kind of alteration you want in the mechanical structure.
How does heat treatment help metals?
Heat treatment assist in improving the ductility of metal in the annealing process. Heat treatment helps in hardening metals. Case hardening helps in hardening only the outer surface of the metal piece keeping the rest of the portion soft and ductile. Machinability of metals gets improved.
How is annealing done?
Annealing is done by heating the metals at the above critical temperature , hold them there for some time and then cool it at a very slow rate in the furnace itself. Annealing is usually done on ferrous and non-ferrous metals to reduce hardness after the cold working process.
What is case hardening?
Case hardening or surface hardening is a hardening heat-treatment process. In the case of hardening, the complete metal piece is heated. But in the case of case hardening, only the outer surface is heat-treated to make it hardened. The inner metal is still soft and ductile.
What is process annealing?
Process annealing is done when metal is heated below the critical temperature, keep it for a suitable time, and then cool it slowly. This process is suitable for low carbon steel like sheet metal and wires. No phase transformation occurs during process annealing, and it’s considerably cheaper than full annealing.
How does heat treatment change mechanical properties?
During the whole process, the mechanical properties get changed due to changes in microstructure. All metallic metals have grains which are nothing but microstructures of crystals. The nature of those grains determines the behavior of the mechanical properties of a metal. Heat treatment changes that mechanical structure by controlling the rate ...
How many watts does an electric oven use?
An electric oven usually uses from 1,500 to 4,000 watts. Space heaters are available in models that use as little as 500 watts. Look for energy efficient models. An electric oven left cracked open at the highest heat can melt temperature dials.
How long does an electric oven stay on?
Electric ovens frequently stay on for many hours at a time without adverse effects. High oven temperatures can heat a room, even with the door closed, though it won’t be effective in a very large space. Opening the oven door will allow the heat to move more freely into the room.
What is the best way to heat a room?
If you need a different heat source for a short time, try a space heater. The wattage used is much lower than that of an oven and it’s designed to heat a room. You can also try kerosene heaters, though they emit an odor.
Why open oven door?
Opening the oven door will allow the heat to move more freely into the room. Electric ovens are not intended for space heating so, understand that it is possible for the appliance to overheat due to prolonged usage and a resulting malfunction may cause a fire.
