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.
What is the process of gradually cooling chocolate?
I expect you are refering to tempering
What is a sentence with the word hardness?
no one likes your Hardness! hardness is not a good character.
What is the hardness of Limonite on the mohs hardness scale?
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
Why do rocks have different hardness?
it has to do with the hardness of the mineral which can be found by moh's scale of hardness
What is the hardness level for en19 material?
approx. 50 HRC after hardening and tempering
Why is tempering applied on quenched steels?
to reduce hardness to prevent the material from becoming brittle

What is the relationship between hardness and ductility?
when ductility increase hardness decrease
Why Strength and hardness of material are decreased by annealing?
because it removes the tempering(hardness) of the object, generally on the surface, and makes it easier to work the metal without ruining your tools or "work" hardening the surface.
What heat treating process makes martensite less brittle?
Tempering. Removes carbon atoms, making the material softer and more ductile at the expense of hardness.
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 ISBN of The Tempering?
The ISBN of The Tempering is 0-8991-9152-5.
What is a term referring to the melting and cooling of chocolate to make candies?
Tempering
The hardness of iron?
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Why quenching steel must be tempered?
Quenching steel involves rapidly cooling it to increase hardness, but this can make it too brittle. Tempering is a process where the hardened steel is heated to a specific temperature and then cooled slowly. This helps relieve internal stresses and makes the steel tougher and more ductile, balancing hardness with flexibility.
