What are the most suitable scenarios for the use of PAG quenchant?
1. What occasions are suitable for using PAG quenchant?
PAG quenching agent is mainly suitable for integral dipping quenching and induction heating quenching of carbon structural steel and carbon tool steel, low and medium alloy structural steel and most carburized steel, spring steel and bearing steel, quenching of mars bulk stainless steel with carbon content not exceeding 0.25, solid solution heating quenching of age-hardened aluminum alloy, etc.  
after the workpiece originally cooled by water quenching oil is changed to PAG quenching agent, single-liquid quenching can be carried out, and once cooled to the end, the quenching effect of high hardness without cracking can be obtained.  
changing from polyvinyl alcohol quenching fluid to PAG quenching agent can overcome the shortcomings of quenching fluid such as easy deterioration and poor control of effective concentration.

2, which occasions are not suitable for the use of PAG quenching agent?
Generally speaking, the workpiece heated by the salt bath furnace is not suitable for quenching in the water-soluble quenching liquid.  
A large number of workpieces are immersed in quenching liquid in the form of dense stacking, which is not suitable for quenching with water-soluble quenching liquid.  
Quenching cooling system in which the quenching tank is too small or the total amount of quenching liquid is too small, and the liquid temperature can easily rise to the cloud point temperature of quenching liquid in production is not suitable for the use of PAG quenching liquid.  
Induction heating spray quenching, if there is no quenching liquid reflux recovery device after spraying, it is not suitable to use PAG quenching liquid, otherwise the consumption is too large.
