Hardening of metals

In hardening, there is no one-size-fits-all method; each material and each end product requires its own specific solution. At Thor Ahlgren, we customize each process to ensure optimal performance and longevity. Below is an overview of the most common methods and how we combine tradition and technology to create better products: 

• Heat treatment: One of the most flexible and cost-effective processes to increase hardness and toughness, especially for steel. This method has its roots in traditional craftsmanship but with today's technology we can perform it with a higher accuracy. 

• Protected curing: A controlled environment that minimizes oxide formation and ensures the desired properties of the material. This is a method we developed for components where surface quality is crucial. 

• Induction hardening: A fast and precise method for specific surfaces. It is ideal for high-precision parts such as shafts and gears - components that require maximum wear resistance. Our modern induction technology enables both speed and accuracy. 

• Surface hardening: Provides a durable surface while maintaining toughness inside the material, giving a perfect balance between hardness and flexibility. We're refining this method to create products that withstand heavy wear without sacrificing mobility.
