ASTM D3520 – Quenching Time of Heat-Treating Fluids (Magnetic Quenchometer Method)

We perform testing by ASTM D3520 to compare the quenching speed characteristics of petroleum fluids using a Magnetic Quenchometer. This test determines the time for a chromized nickel ball to cool when quenched in the test fluid. ASTM D3520 is useful for selecting fluids with respect to quenching speed characteristics desired for metal quenching applications.
