Quenching Oil Aging Resistance

Quenching oil aging resistance: The oil remains stable under heat and oxidation, ensuring consistent cooling during welding.

Physical-Chemical Mechanism of Action

Quenching oils consist of hydrocarbons with a high degree of saturation. They are stable against cracking and oxidation because they have few unsaturated bonds that could lead to reactions.

Metallurgical Relevance & Risks in Welding

Poor quenching oil aging resistance can lead to oxidation processes and cracking in the oil. This impairs the cooling effect, leading to uneven weld strength and possible cracks.

Workshop Practice & Action Instructions

Use quenching oil with high oxidation resistance. Check the oil regularly for quality and replace it at signs of change or wear.
