Quenching oils are mainly used in the Steel Industry to facilitate hardening of metal by controlling heat transfer during quenching. It also enhances wetting of the metal during quenching to minimize the formation of undesirable thermal and transformational gradients which may lead to increased distortion and cracking.
Quenching oil is required to be monitored regularly to monitor degradation. Oil degradation of Quenching fluids is often accompanied by sedimentation and sludge formation. This sludge / varnish restrict the proper hardening of metal component & lead to defects on the metal surface.
Chem-TechTM carries out monitoring of Quenching Oils for the following properties:
Chem-TechTM carries out testing of Quenching oil as per internationally accepted ASTM, ISO & IS Test Standards.

Kinematic Viscosity is a measurement of the resistance of the oil to flow through a capillary tube of the viscometer. It is the most fundamental property of a lubricant. Viscosity of lubricants is measured in case of fresh oils to check the Grade of the oil . in case of used oils it gives idea about change in physical properties due to oxidation, dilution or any external contamination. It is the most fundamental property for testing of any lubricant or petroleum product.
Methods Adopted by Chem-Tech for Viscosity Determination:
Total Acid Number determines the amount of acid present in the lubricant. Acidity of the lubricant increases due to the stresses or environmental factors affecting the lubricant. Excess amount of acid in the lubricant will lead to corrosion or failure of equipment.
Methods adopted by Chem-Tech Laboratories for Acid Number Analysis:
Water or Moisture is the most common contaminant in any lubricant or petroleum product. Monitoring the level water in sample is of prime importance to avoid malfunctioning of the equipment or machine.
Water content in petroleum products can be determined by following 4 test methods:
Methods Adopted by Chem-Tech for Water / Moisture Content Determination:
Flash Point is the lowest temperature at which the vapours of the petroleum product catches fire momentarily in presence of air when an ignition source is applied to the sample.
Flash point are normally conducted by three methods:
Methods Adopted by Chem-Tech for Flash Point Determination:
Elemental Analysis by ICP determines the amount of Wear metals , Contaminant Metals and Additive Metals present in a Lubricant. Elemental Analysis can detect upto 24 elements in the lubricant. These includes all the particles present in oil upto 5-10 microns in size.
It gives an idea about the amount of Wear and Contamination in the Lubricant. It is one of the primary tests conducted for Trend Analysis or Predictive Maintenance of the Equipment.
Test Methods adopted by Chem-Tech for Elemental Analysis:
This test determines the total sediments present in petroleum . This is a Chem-Tech Laboratories validated method, It is modification of ASTM D 893 for determination of Total Insoluble content in Toluene. It is a centrifugal method for determination of Insoluble content.
It determines wear metals, dirt dust and debris present in petroleum products & Lubricants.
