What is Normal Hardening? Working and Benefits

Normal Hardening

Normal hardening is a process used to improve the strength and durability of metals, alloys, and polymers. By subjecting these materials to high temperatures and rapid cooling, the materials can become more resistant to wear and tear as well as corrosion. This process has been around for centuries but has seen a recent resurgence in popularity due to its ability to provide cost-effective solutions for many industries. Let’s take a closer look at what normal hardening is, how it works, and how it can benefit you.

What is Normal Hardening?

Normal hardening is a process that involves heating material to an elevated temperature before quickly cooling it with water or oil. The purpose of this process is to increase the hardness of metals, alloys, and polymers without compromising their ductility or machinability. This method can be used on both ferrous – such as steel – and non-ferrous metals – such as aluminium or copper alloys – but it is most commonly used with steel due to its wide range of applications in various industries.

How Does Normal Hardening Work?

At its core, normal hardening works by strengthening the crystal structure of the material being treated. When heated up above what’s known as the “critical temperature” for a particular metal or alloy, atoms within the material begin moving around more freely, which increases their diffusion rate. When rapidly cooled afterwards, these atoms are frozen in place, which results in a much harder material than before. This increased hardness makes the material more durable against wear and tear as well as corrosion from exposure to various substances over time.

How Can It Benefit You?

Normal hardening can benefit you in multiple ways, depending on your industry or application. For example, if you are involved in manufacturing parts that require frequent machining operations, then normal hardening can make those operations quicker and easier while extending the life of the tooling being used (i.e., drill bits). Additionally, this process can also reduce production costs by reducing waste from scrapped parts since they have been strengthened through normal hardening, making them less prone to failure during operation or assembly. Finally, this process can also increase safety by reducing potential failures due to weakened components which could lead to catastrophic consequences for workers depending on your industry/application.


Normal hardening is an age-old yet still relevant process that has many applications across numerous industries today thanks to its ability to strengthen materials without compromising their ductility or machinability. Not only does normal hardening make materials stronger against wear & tear/corrosion, but it also makes certain operations easier while also helping reduce production costs/increase safety when done correctly.
