What is quench fluid?
Quenching oil and heat treatment fluids are designed for rapid or controlled cooling of steel or other metals as part of a hardening, tempering or other heat-treating process. Quenching oil serves two primary functions.
Can I use motor oil to quench?
1) Motor Oils Motor oils are a common type of quenching oil used in both blacksmithing and bladesmithing applications. New and used motor oils can be used for quenching and are both widely available. New motor oil is typically cheaper to use than commercial quenching oils.
Which is commonly used quenching agent?
Despite reports of decomposition of DBPs caused by some quenching agents, particularly sulphite and thiosulphate, a survey of the literature shows that they are still the most commonly used quenching agents in analysis of DBPs.
What happens when you quench steel twice?
Double quenching indeed leads to grain refinement and overall microstructural refinement. However, the second austenization temperature must be the same or lower than the first austenization temperature to achieve this.
How long is quenching oil good for?
Quenching and martempering oils deteriorate during use, although most premium quenching oils can last more than 10 years when given reasonable use and care.
Why is quenching important in chemistry?
Rapid cooling from an elevated temperature, e.g., severe cooling of the reaction system in a short time (almost instantaneously), “freezes” the status of a reaction and prevents further decomposition or reaction.
Why is quenching done chemistry?
Chemical quenching means that a reactant is introduced to favor an endothermic reaction with an associated reduction of temperature. Also, the lowered temperature of the introduced reactant strengthens the effect.
Who carries out quenching oil testing?
Chem-Tech Laboratories carries out Quenching Oil Testing as per internationally accepted ASTM, ISO & IS Test Standards.
What is quench oil characterization and why is it important?
Quench oil characterization is necessary to ensure optimal quench process control. Quench oil characterization is readily performed by measuring a series of physical properties including: viscosity, water content, neutralization number, precipitation number and flash point (Table 1).
How do you test for water in quench oil?
This is the basis of a qualitative field test for water in quench oil. The most common laboratory tests for water contamination are either Karl Fischer analysis (ASTM D6304) or distillation (ASTM D95).
What is normal speed quenching oil used for?
Normal-speed quench oils have relatively slow rates of cooling. Normal-speed oil has a 13-20 second GMQS quenching speed. These oils are used in applications in which the harden- ability of the ferrous alloy is high enough that maximum mechanical properties are obtained even with a slow cooling rate.
