quenching is rapid cooling of steel to be heat treated, there are basically four types of quenching:

1- by water.

2- by oil.

3- by air.

4- by furnace.

water oil air furnace

tensile stress 175*104 112*104 88*104 52*104

The purpose of salt bath in sword making?

I don't know specifically about sword making, but I do know that immersing hot steel in a salt bath results in very fast quenching (cooling). It has probably been found that the properties of the steel after a salt bath quench works well for swords.


What does steel bound mean?

Steel-bound means "bounded by steel."


Why hardenability of plain carbon steel is less?

hardness is defined as a resistance to plastic deformation or penatration.Hardness is defined as the ease with which hardness may be attained by quenching . It is also defined as the ability to develop maximum hardness by quenching.It is the process to have a hardened layer of marten site after quenching and also to have high hardness at same given depth. The material which having low critical cooling rate have high hardenability.The factors which reduce critical cooling rate increase the hardenability.alloy steels have low critical temperature. In plain carbon steels are contain not more than .5% of silicon and 1.5% of manganese.These steels are strong,tough,ductile and used in expensive materials.Increase in hardness and strength in plain carbon steel is depend upon the presence of carbon content.


What purpose steel may be heat treated?

Steel is heat treated to enhance its mechanical properties, such as hardness, strength, and toughness. Processes like annealing, quenching, and tempering alter the steel's microstructure, allowing it to better withstand stress and fatigue. Heat treatment can also improve ductility and reduce brittleness, making the steel more suitable for various applications in construction, manufacturing, and automotive industries. Ultimately, these treatments optimize performance and extend the lifespan of steel products.


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.

Why does quenching in oil produce different results than quenching in water?

The fluid for quenching is specific for each type of steel; choosing an inappropriate fluid lead to bad results.


Why it is necessary to temper hardened steel immediately after quenching?

to avoid the high internal stresses caused by quenching and to get tempered Martensite that is less brittle


Which item can be tempered is it steel or salt or water?

Steel can be tempered (hardened by heat treatment followed by quenching -cooling).


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.


On quenching high carbon steels get hardened but austenitic stainless steel dont why?

The metallurgical transfer motion behaviour during quenching is influenced by cooling rate, carbon concentrration , alloying elemnts and stress


When water is used for quenching a plain carbon steel and maximum hardness is required what temperature should the water be?

55 degrees.


How could end quenching change the hardness?

End quenching can change the hardness of metals by introducing different crystal structures. Steel is commonly quenched to introducing martensite, a very hard form of steel crystalline structure.


What is t in en19t steel?

In EN19T steel, the 'T' stands for "treated." This indicates that the steel has undergone a heat treatment process to enhance its mechanical properties, such as hardness and strength. This treatment typically involves processes like quenching and tempering.


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.


How do you spell quenching?

That is the correct spelling of "quenching" (eliminating, extinguishing).


Is high speed steel stronger than stainless steel?

You cannot have a general answer for this. The comparison in strength depends on the chemical composition or grade of each, as well as the heat treatment and quenching method each received.
