Neutral Hardening – Metals Technology

Oil Quenching Process Overview

Oil quenching is a heat treatment process that involves rapidly cooling metal components in oil to achieve desired material properties. The process generally consists of three primary stages:

Heating: The component is uniformly heated to a specific temperature, usually above its critical transformation temperature.
Quenching: The heated component is then immersed in an oil bath. The oil acts as a cooling medium, extracting heat from the component.
Tempering: The component is heated again but to a much lower temperature than the initial heating. This step is essential to relieve stresses induced during the quenching process and enhance the metal’s ductility.

Neutral Hardening benefits

Neutral hardening refers to a heat treatment process where the component is heated in a neutral atmosphere, preventing any chemical reactions on the surface. Here are the benefits:

Improved Mechanical Properties

Neutral hardening significantly enhances the mechanical properties of metals, including strength and wear resistance.

Controlled Atmosphere

Conducting the process in a neutral atmosphere prevents surface contamination and ensures consistency in properties.

Less Distortion

Compared to other quenching mediums like water, oil quenching usually causes less distortion and cracking.

Enhanced Toughness

The combination of neutral hardening and oil quenching results in a structure with enhanced toughness and ductility.
