The temperature needed for hardening varies depending on the material being processed. For example, steel typically requires heating to temperatures between 800°C to 1,200°C (1,472°F to 2,192°F) for hardening. In contrast, polymers may need to be cured at much lower temperatures, often around 150°C to 200°C (302°F to 392°F). Always refer to specific material guidelines for precise hardening temperatures.

What is precipitation hardening?
Precipitation hardening, or age hardening, is a heat treatment process used to increase the strength and hardness of certain metal alloys. It involves heating the material to a specific temperature, holding it there for a period of time, then cooling it rapidly to room temperature. This process allows fine particles or precipitates to form within the metal structure, strengthening it.
Is the steel strain hardening exponent temperature dependent?
yes, with increased temp, the s.h.e decreaseshiAccording to your answer . I must say that as I know , when we anneald metals ( e.g. Iron ) the S.H.E increased while you can decreas it by cold-work .
What are the heat treatment processes involed in making a hammer?
To make a hammer, the main heat treatment processes involved are heat treating for hardening and tempering. The hammer head is heated to a specific temperature for hardening, then quenched in a cooling medium to achieve the desired hardness. Tempering is then done by reheating the hardened hammer head to a lower temperature to improve toughness and reduce brittleness.
What is hardening of the cells called?
Hardening of the cells is called sclerosis. This term is commonly used in medical contexts to describe the process of abnormal thickening, hardening, and scarring of tissues.
How fast does a drop of wax harden?
The hardening speed of a drop of wax depends on its composition, temperature, and surrounding conditions. Typically, wax hardens relatively quickly, within a few minutes to an hour after being dropped. Factors like the type of wax, airflow, and thickness of the drop can influence the hardening process.
What conditions are needed for hardening olive oil by reacting it with hydrogen?
the temperature needs to be 60c a nickel catalyst should be used to speed up the reaction
What is age hardening?
age hardening is the result of precipitation of the one or more compounds whose solubility decreases with decrease temperature from a solid solution. For each alloy susceptible to aging, there is a unique range of time-temperature combinations to which it will respond to age hardening.

What is the difference between tempering and hardening in the context of metal processing?
Tempering and hardening are both heat treatment processes used in metal processing. Hardening involves heating the metal to a high temperature and then rapidly cooling it to increase its hardness and strength. Tempering, on the other hand, involves reheating the hardened metal to a lower temperature to reduce its brittleness and improve its toughness. In essence, hardening makes the metal harder and stronger, while tempering makes it tougher and more ductile.
What are main requirements for an alloy to depict age hardening?
The main requirement for an alloy system to respond to age-hardening is a significant decrease in solid solubility of one or more of the alloying elements with decreasing temperature.
Would hardening oil make it healthier?
Hardening sunflower oil makes it a solid at room temperature which is suitable for spreading so I don't think that it makes much difference. I could be wrong though. Sorry!

What type of hardening is done to lathe bed?
mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
How does surface hardening different from true hardening?
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
