The main purpose of the quenching (hardening) process is:
• controlled cooling of heated metal,
• increasing material hardness (raising the HRC value),
• ensuring structural stability,
• preventing cracks and deformation.
Quenching oils are one of the most optimal media for this process because, compared to alternatives such as water or air, they provide more stable cooling and better protection against oxidation.
Why Avtoil Quenching Oils: Brand Advantages
Avtoil’s quenching oil line is specially formulated for high-performance heat treatment. The brand offers high-quality industrial oils that meet international standards.
Advantages of Avtoil Quenching Oils:
• Fast and stable cooling rate – increases HRC hardness.
• Minimized caléfaction effect – prevents formation of a vapor blanket on the metal surface.
• Reduced deformation risk – high stability even for thin blades and parts.
• Crack (tapure) probability reduced to near zero.
• Low volatility and high thermal stability.
• No need for additional washing between heat-treating cycles.
• Protects metal against oxidation.
Fast Cooling – A Key Factor for High HRC in Blade Production
One of the most important factors in knife-making is the final hardness value. The faster the cooling, the harder and more durable the resulting structure becomes.
Avtoil’s fast-cooling products such as Quench Oil Q20 and Quench Oil Q60 provide maximum performance for:
• blade manufacturers,
• precision machining specialists,
• industrial cutting tool producers.
These oils minimize vapor insulation on the metal surface, ensuring stable cooling and superior heat-treatment results.
Reducing Deformation and Crack Risks
Although large mechanical parts are less prone to deformation, thin components like blades become more brittle after high temperatures and may lose their shape.
With its special formula, Avtoil Quenching Oils:
• regulate surface tension,
• distribute cooling evenly,
• reduce internal stresses in the material,
• minimize crack formation.
As a result, no additional machining, straightening, or remanufacturing is required.
Comparison of Quench Oil and Other Quenching Methods
Water Quenching
• Very fast, but creates a high risk of deformation and cracking.
Air Quenching
• Slow, may reduce hardness levels.
Polymer / Gas / Molten Salt
• Technologically complex and expensive.
Oil Quenching (the most balanced method)
Avtoil quenching oils are the ideal choice because:
• cooling is stable and controlled,
• metal is protected from oxidation,
• safety and performance are well-balanced.
