Annealing Steel - Carbon Steel Annealing Services 
Annealing Steel - Carbon Steel Annealing Services

At Accurate Metal Products (AMP), we’ve provided metalworking solutions to customers across a range of industries for over 25 years. In addition to our core metal fabrication capabilities (e.g., laser cutting, plasma cutting, and oxy-fuel flame cutting), we offer a variety of material treatment and finishing services to ensure the components we deliver have the necessary functional and/or aesthetic properties. For example, annealing improves ductility and reduces hardness in materials.

Annealing 101

What Is Annealing?

Heat treatments involve heating a metal to a temperature below its melting point and then cooling it in a controlled manner. The heating-cooling process enhances existing properties or adds new properties, such as strength, durability, or ductility, making the material easier to work during the manufacturing phase or better suited for the intended application. Annealing is a heat treatment used to increase ductility and decrease hardness, which means the material is easier to draw into components (e.g., wires) and harder to break when subject to impact forces. It is commonly used for steels, including carbon steel, and other alloys.

The Annealing Process

Metals are made up of crystal structures referred to as grains. These grains can align in many ways, some of which cause internal stresses in the material. The annealing process removes existing stresses caused by old grains and produces new grains that do not cause stress, resulting in a better material.

The steps in the annealing process are as follows:

  1. Recovery. The metal is heated (typically by a furnace) to its recrystallization point, which relieves its internal stresses.
  2. Recrystallization. The metal is heated to above its recrystallization point but below its melting point, which allows new grains to grow without forming preexisting stresses.
  3. Grain Growth. The metal is cooled at a specific rate to ensure the controlled growth of new grains.

Benefits of Annealing

Annealed materials are more ductile and less brittle. These properties make them easier to form, machine, and otherwise work and better for applications where impact is a concern.

Annealing Services at AMP

The metalworking experts at AMP offer subcritical annealing capabilities for carbon steel, and other steel alloys. This heat treatment method involves heating materials at slightly lower temperatures to focus on material stress relief and stabilization.
