Frequently asked questions
Clear answers before you send a component
What is industrial heat treatment?
It is the controlled heating and cooling of metal to modify properties such as hardness, strength, toughness, machinability or dimensional stability.
Which materials can be heat-treated?
Many ferrous and selected non-ferrous grades can be treated. Suitability depends on the exact material grade, component geometry and required properties.
What is case hardening?
Case hardening creates a hard, wear-resistant outer layer while retaining a tougher core on suitable components.
What is the difference between hardening and tempering?
Hardening develops hardness through heating and quenching; tempering follows to adjust brittleness and achieve the required hardness–toughness balance.
Why is stress relieving required?
It can reduce residual stress introduced by machining, welding, forming or previous processing and support dimensional stability.
Do you treat custom components?
Yes. Each enquiry is evaluated using the customer’s material grade, drawing, specification, quantity and application.
How can I request a quotation?
Send the material grade, component drawing, dimensions, process, hardness, quantity and required delivery date through our enquiry page.
