  • QUENCHTASH 40 (HEAVY)

QUENCHTASH grades are premium quality fast quenching oils made out of highly refined best quality mineral oils.  In order to judge its superiority over conventional quenching oils it is necessary to have brief idea about the theory of quenching.

   

THEORY OF QUENCHING:

STAGE OF COOLING: When hot steel is quenched.  It vapourizes some of the surrounding oil.  A pocket of vapour insulates the steel from the liquid and retards the removal of heat.  As the steel cools somewhat, there is a second stage in which the quenched part is in contact with violently boiling liquid and head is removed rapidly.  In the third stage of liquid contact the cooling rate is slower.

CONDITION FOR MAXIMUM HARDNESS & MINIMUM DISTORTION:  To develop maximum hardness the quenching oil should cool the steel as rapidly as possible during the first two stages (the critical hardening range).  To minimize distortion and cracking, the oil should cool the steel slowly during third stage and conventional mineral oils are too slow during the first two stages, "Quenchtash" cools steel at the desirable rate in each stage.

EFFECTS OF AGITATION:  Mechanical agitation of the bath increases the quenching speed of conventional quenching oils by dispersing the blanket of insulating vapour and increasing the rate of heat transfer.  However, there is a limit to the quenching speed and resultant hardness which can be obtained with agitation.  Beyond that limit  with moderate agitation is effective because of its fast quenching speed.

APPLICATION:

SPECIALITY OIL 70 is a special quality quenching oil added with special additives in order to give oxidation and rusting protection, rapid quenching rate, high temperature stability, deposit preventive ability etc.. It is used whenever the nature of steel, the size and the shape of the parts, or other conditions make it is difficult to get satisfactory results with conventional quenching oils, and also when steel parts packed so tightly in baskets that interior does not benefit from full circulation of the quenching oil.
