Hardening is about increasing the hardness, strength, toughness or durability of the steel to adapt it to its final use. Hardening and choice of method varies depending on whether it is structural steel, toughening steel, case hardening steel, ball bearing steel, automatic steel, stainless steel, tool steel or high-speed steel. These different steel grades consist of different alloy elements and their composition – which affects the hardening. Carbon is the most common element and most important for hardness when hardening.
The actual hardening of the material occurs by cooling in the process, usually in oil or gas, and the properties of the material are affected by how quickly the cooling occurs. Usually the hardness of the steel decreases the slower the cooling is. For maximum hardness when hardening, the material is switched off quickly, so-called forced cooling. Hardening with air cooling versus oil cooling can thus give the material different properties, even if the steel has the same chemical composition.

BENEFITS FOR YOU
Our process-controlled furnaces control everything from gas flows, carbon levels and temperatures to cooling, when hardening. This is done through unique programs, often created uniquely for our customers and entirely based on their needs. We have our own calibration equipment and can thus carry out the necessary checks on the machinery – all to ensure the parameters of the hardening process. Our hardening proficient staff can assist in the selection of materials, discuss any shape changes and of course recommend the best hardening method for your particular product. That’s why several of Sweden’s largest companies partner up with us!
Quality in the hardening process, knowledge of metallurgy and flexibility in our services are values highly appriciated. Therefore, do as our other customers and give us a call to discuss the needs of your particular company!
KNOWLEDGE & EDUCATION
Since we´ve been active in this business for almost 50 years now our knowledge and experience of hardening, heat treatment and materials is broad. As a result of our know-how we offer HärdWiki™ and HärdAcedemy™. Both products are highly appriciated by customers we support.
This is a product only available in Swedish (for now). It contains more than 50 pages of know-how in hardening, heat treatment and metallurgy. It´s written by our own metallurgists and hardening experts and we update it several times a year. We are happy to share it with our customers totaly free of charge!
EDUCATION AND CLASSES
Is your business in need for more knowledge regarding hardening, heat treatment and metallurgy? Are your employees updated on processes and materials? Do they know how this affect your production?
As your partner in overall heat treatment solution we offer you educational courses and classes. We belive this would add value to your business and make your production more profitable!
