Industrial Quenching Oil
Martensitic quenching oil, class 2
Step Quenching Oil for Heat Treatment with Controlled Distortion
Class 2
Martempering
Deformation Control
Martempering oil (marquenching oil) Class 2, designed for the heat treatment of carburized gears, bearing rings, axle shafts, and other deformation-sensitive precision parts. Available for wholesale supply, distributor supply, and OEM or private label cooperation.
Product Description
Martensitic grade quenching oil Grade 2 is characterized by a short vapor phase stage, rapid high-temperature cooling, and a relatively high convection start temperature. It is designed for martensitic stepped quenching of carburized or cyanided gears and other small to medium-sized parts in controlled atmosphere multi-chamber or conveyor furnaces.
The product provides uniform hardness, good hardenability, improved distortion control, and a clean workpiece surface after quenching. Its thermal stability and performance characteristics help maintain consistent quenching quality in industrial heat treatment processes.
Typical applications include bearing steel and case-hardening steel for bearing rings, precision components, automotive and tractor gearboxes, axle shafts, and other distortion-sensitive parts.
