|13. HEAT TREATMENT QUENCH FLUIDS
||Synthetic (Aqueous solution)
|Alpha Quench A: Aqueous solution heat treatment quenching fluid
(240cSt) designed for high initial quenching rate in the critical
hardening range to develop maximum hardness coupled with slow
final speed throughout the lower temperatures to minimize
distortion. It is an aqueous solution of liquid organic polymers and
non-nitride corrosion inhibitors. Alpha Quench A is suitable for medium carbon, low
alloy steels (such as 760); high carbon, medium alloy steels (O1); induction
hardening of medium carbon steels and solution annealing of aluminum castings.
Heat Treatment Water Conditioner: is a nitrite based corrosion control product for
use in straight water quenches to control rust on steel parts.
||Alpha Quench 5300- high speed quench oil. Heat treatment
quenching oil (20cSt) designed for high speed quenching operations
(up to 120 deg C) to develop maximum hardness and minimal
distortion. AlphaQuench is formulated with parafinic oil for maximum
thermal stability and longer bath life. It is good for tightly packed in basket and
optimal circulation is not possible. AlphaQuench 5300 has low viscosity for less
drag out rates.
|Marquench 325: Heat treatment quenching oil (63cSt) designed for marquenching
operations (up to 177oC) which require a medium quenching speed, in order to
develop maximum hardness and minimal distortion. Marquench 325 has low
viscosity, slower cooling in the convection phase in order to minimize distortion. It
is formulated with a paraffinic base stock for maximum thermal stability plus a high
flash point to minimize the risk of fire hazard. Marquench 325 is fortified with
anti-oxidants for a longer bath life.
Marquench 900: Heat treatment quenching oil (180cSt) designed for higher
marquenching operations (up to 204oC) which require a faster speed, in order to
develop maximum hardness and minimal distortion. Marquench 900 has high
viscosity, slower cooling in the convection phase in order to minimize distortion and
a faster cooling
after convection phase. It is formulated with a paraffinic base stock for maximum
thermal stability plus a high flash point to minimize the risk of fire hazard.
