Tempering Steel is the second stage or process performed on some steels it may have to go through, while it is being heat treated. Once some metals have been heated then quenched or AKA cooled quickly in air , oil or water it becomes hardened very hard this process is know as the Hardening process but also makes steel very brittle like glass to give that steel part its toughness back again the heat treat shop then tempers it after its been hardened this is known as the Tempering Process and takes out some of the hardness, but puts back some of the steel parts toughness so it becomes tougher and more resistant from cracking or braking into piece's when used. This is also known as Tempered Steel.

What is the purpose of tempering a quench hardened plain carbon steel?
Tempering is applied to quench hardened plain carbon steel to: 1. reduce brittleness. 2. increase ductility. 3. increase toughness. 4. relieve stresses in the martensite structure. Increase in tempering temperature lowers the hardness. The reduction in hardness of the quenched steel depends upon the composition of the alloy and the exact value of the temperature applied.
Can spring steel be heat treated?
Definately spring steel can be heat treated and it has to be heat treated before it can be functioned as a spring. The common way to heat treat spring steel is by quenching and tempering.
What is the process of gradually cooling chocolate?
I expect you are refering to tempering
What happens to steel when put in a fire?
If the fire is hot enough, and there is enough oxygen, the steel will burn. (think cutting torch) The simplest answer is that the steel heats up. A cutting torch doesn't "burn" the metal away... it melts the metal along your cutting line. Very few chemicals can oxidize steel with enough ferocity to burn it with a flame. A couple of exceptions that I have seen in my career were F2 and ClF3. Of course those are very strong oxidizers. Heating steel to a prescribed temperature then either quenching it quickly or holding the temperature a a certain level for a period of time will alter the grain structure and therefore the properties of the steel. Think tempering. You can learn much more about that by researching steel phase diagrams. Time-temperature relationships are the oldest and most common methods of changing a metals strength and hardness.
How to heat treat 440c stainless?
Heat treating of tool steel is a fairly simple process. Precautions must be taken to protect the tool steel from exposure to oxygen. Tool steels are susceptible to decarburization due to their relatively high heat treating temperature. Stress relieving of the tool steel may be necessary, especially if the tools are complex in design or have been heavily machined. Preheating may be required to reduce the chance of cracking or distortion. The tool steel is generally heat treated between 1500 and 2200F, depending on the grade of tool steel. The tool steel is held at the austenizing temperature longer enough for the elements to be dissolved into solution, then the tool steel is quenched. Quenching can be performed in air, water, oil or vacuum. The quenching medium is determined by the required quench rate and alloy content of the chosen grade. After quenching, the tool steel must be tempered. Tempering is usually perfromed between 350 and 1200F.
What is tempering of steel?
molding
What happens on a molecular level when tempering steel?
Grain Size of the steel get changed. Steel Become more hard and it become brittle.
What has the author Fridolin Reiser written?
Fridolin Reiser has written: 'The hardening and tempering of steel' -- subject(s): Steel
Why is steel better than bronze?
Because of carburization, quenching(heat treatment of steel) and tempering of quenched steel.

How can steel cutting tools be used to shape steel objects?
Steel cutting tools that are hardened by tempering them can cut softer, untempered steel. Steel that is high in carbon content can be made tougher than low-carbon steel.
What is the chemical composition of metal en-45?
en 45 is a silicon mangenese spring steel, supplied in the as rolled contition. This steel is suitable for oil hardening and tempering.
When was The Tempering created?
The Tempering was created in 1983.
How many pages does The Tempering have?
The Tempering has 198 pages.
What is the tensile strength of 4140 steel?
It will be at least 117,000 psi and as high as 290,000 psi - the range depends on the tempering temperature and heat treat
Can spring steel be heat treated?
Definately spring steel can be heat treated and it has to be heat treated before it can be functioned as a spring. The common way to heat treat spring steel is by quenching and tempering.
Is high carbon steel stronger than tempered steel?
Tempered steel is not a classification of steel. It is a term used to indicate that the steel has undergone proper heat treatment in which case..yes, the steel that has been properly hardened and tempered would be stronger. This answer assumes that the high carbon steel is in its annealed state and has not received heat treatment and tempering of its own.
