Aqua Quench 364

A WATER SOLUBLE SYNTHETIC QUENCHANT FOR THE HARDENING OF FERROUS ALLOY OIL-FREE, NON-FLAMMABLE

 

Aqua-Quench 364 is a concentrated aqueous solution of poly-oxythylene glycol.  This product is inversely soluble in water and is inhibited against ferrous corrosion.  Aqua-Quench 364 has quenching characteristics which provide a slower cooling rate in the convection phase or third stage of the time-temperature cooling curve.

APPLICATION

 

Aqua-Quench 364 solutions cover a wide range of quenching effects depending on solution concentrations and temperatures.  The quenching characteristics of Aqua-Quench 364, as demonstrated by time-temperature cooling curves, have a slower rate of cooling during the convection phase.  This slower cooling rate in the third stage of the quenching mechanism will eliminate the tendency for quench cracking or distortion problems in some alloys and work pieces.

 

Aqua-Quench 364 is formulated to quench ferrous alloys and is recommended as a quenchant in the following processes:

 

Surface Hardening

 

Gears, spindles, camshafts, bearing journals, drill pipe, etc. that are induction or flame heated are traditionally quenched in oil.  Aqua-Quench 364 can replace the quenching oil, eliminate the fire hazard and reduce smoking.

 

Forgings

 

Steel forgings of high and low hardenable material can be hardened in solutions of Aqua-Quench 364 at 8 - 25% concentration.

 

Castings

 

Aqua-Quench 364 is recommended for quenching of steel castings at concentration depending on alloy from 8 - 25%.  Nodular and ductile iron castings can be quenched in solutions of Aqua-Quench 364 at 20 - 30% concentration.

 

The above applications are examples.  The actual solution concentration of Aqua-Quench 364 may vary depending on the workpiece, chemistries, dimensions, equipment being used, etc.

 

CONCENTRATION CONTROL

 

The concentration control of Aqua-Quench 364 solutions is based on its Kinematic Viscosity.

 

A sugar refractometer can be used for in-shop concentration control in Aqua-Quench 364 solutions.  The factor to be used with the sugar refractometer is 2.5 for new solutions. 

 

The concentration of new Aqua-Quench 364 solutions is determined by multiplying the refractometer reading by the factor 2.5.  As polymer quenchant solutions are used, they become contaminated.  This contamination in time will affect the solution's refractometer reading, making the solution concentration obtained by the sugar refractometer erroneous.  Therefore, we recommend a periodic solution concentration check by Kinematic Viscosity.  The periodic concentration check by Kinematic Viscosity is routinely performed in our Valley Forge Technical Center free of charge to our customers.

 

CLEANING

 

Due to the inverse solution of Aqua-Quench 364, parts quenched in Aqua-Quench 364 solutions will have a polymer film covering them.  This polymer film is easily removed by rinsing the quenched part in plain cold water.

 

Parts that have been tempered before cleaning may require longer cleaning cycles to remove the dried on polymer film.

 

SHELF LIFE

 

Under normal conditions, the recommended shelf life for Aqua-Quench 364 is twelve months.
