Assessment of Quenching Intensity and The Hardening Power
ASSESSMENT OF QUENCHING INTENSITY AND THE HARDENING POWER,
Workshop on Quenching, Mangalore, 2008.
Reasons why complete and precise information on quenching intensity is required Grossmann’ s quench severity factor “ H” and its shortcomings. GM – Quenchometer test. Industrial quenching oils – Determination of cooling characteristics – laboratory test method (ISO-9950). Standard test method for determination of cooling characteristics of aqueous polymer quenchants by cooling curve analysis with agitation, Tensi method (ASTM D 6482-99). Methods for cooling curve analysis. Determination of the hardening power. Workshop designed Temperature Gradient System (TGS) for quenching analysis. Calculation of Heat Transfer Coefficients (HTC). Flux-Sensor for determination of heat transfer coefficients at High Pressure Gas Quenching (HPGQ) in vacuum furnaces.
