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.
Steel can be tempered (hardened by heat treatment followed by quenching -cooling).
to avoid the high internal stresses caused by quenching and to get tempered Martensite that is less brittle
How the Steel Was Tempered was created in 1932.
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.
The duration of The Way Steel Was Tempered is 1.68 hours.
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.

Non tempered steel
The fluid for quenching is specific for each type of steel; choosing an inappropriate fluid lead to bad results.
Tempered Steel - 1918 was released on: USA: 23 June 1918
Tempered steel has both strength and the ability to change form under the right amount of pressure. Tempered steel can be made from both low carbon and high carbon steels.
