How We Use Heat Treatment
At CanForge, you can be assured that we make the experience of working with us as simple as possible. From our first conversation to the finished product, CanForge will ensure your products meet the specifications you need. As part of our product development process, our quote request form allows you to clarify which type of heat treatment your CanForge product will require. This means we’ll be able to create an accurate quote that reflects the costs associated with the specific type of heat treatment you require.
CanForge offers several types of heat treatments based on the particular needs of the forging project. These treatments are used to produce high-quality forgings that are superior in strength and durability. Depending on the specifications of the project, the heat treatments will prepare the forging for the impact it will be exposed to in its application.
We supply forged products that undergo these types of heat treatments:
Normalize
Normalizing is used to increase the strength of a forging by modifying its grain size for consistency. This process requires the forging to be heated to a specific temperature and then cooled in still air. This heat treatment is generally used for alloy steel and carbon forgings.
Quench and Temper
This heat treatment method is used to increase the hardness of a forging without compromising its integrity. After heating the forging to the specified critical temperature, it is cooled with water, or oil to return it to room temperature quickly. The forging then undergoes a second heat treatment known as tempering that restores softness. This prevents the forging from being too hard that it snaps or shatters. These two heat treatments are used in combination for forgings with high pressure applications.
Stress Relieved
Stress relieving is a method applied to forgings to reduce the structural impacts created by the manufacturing process. Forgings undergo several changes like bending, boring and machining. The impact can create new stresses in the forging that need to be addressed. This heat treatment decreases the effects of these new stresses by heating the forging to a lower temperature and holding it at this level until these stresses are reduced. Stress relieving helps prevent cracking and distortions in the final product.
Process Annealed
Process annealing is typically used for low carbon steel forgings to reduce their hardness. In this method, the forging is heated to a lower temperature compared to a normalizing heat treatment. The forging is slowly cooled in still air, which alters its grain size and flow. This heat treatment improves machinability by making the forging easier to manipulate. Process annealing can also improve electrical conductivity.
