The Secret of High-Precision Heat-Treated Steel Strips: Martempering and the Advantages of Our EBNER Continuous Heat Treatment Furnace

Special steels are critical materials that directly affect the performance and durability of components.
In automotive parts and precision machinery, even small distortions or internal stresses can significantly
impact overall product reliability. Therefore, the choice of heat treatment is not just a processing step
It is key to ensuring product quality.

Martempering is a quenching process in which steel is first heated to form austenite,
then cooled to a specific temperature and held isothermally before being air-cooled to transform into a martensitic structure.

Features of Martempering

• Reduces internal stress and cracking caused by rapid quenching

• Produces a uniform and stable martensitic structure

• Maintains high hardness while improving dimensional accuracy and durability

Compared to conventional quenching, martempering allows precise temperature control,
effectively minimizing internal stress and deformation in the steel.

We use state-of-the-art continuous heat treatment furnaces from EBNER (Austria), enabling stable and continuous martempering.
While martempering is an ideal heat treatment method, it requires extremely precise temperature control,

and many heat treatment companies are unable to implement it reliably. 

Our process ensures low internal stress, minimal deformation, and consistently high-quality steel strips.

A. Automotive Parts Manufacturers

Automotive parts demand extremely high reliability.
Our steel strips have passed stringent audits and are supplied continuously.
Precision heat treatment ensures the components remain stable and reliable in service.

B. Precision Machinery Components
The steel strips can meet flatness tolerances of 0.1% across the width.
In products composed of thousands to tens of thousands of parts, each part's precision directly affects overall quality.
Our steel strips meet these demanding requirements and are highly trusted by customers.

C. Hand Saw Steel
Some customers process the steel strips into final products and sell them under their own brands.
Direct feedback from users indicates excellent durability and cutting performance,
clearly demonstrating the reliability of our steel.

By combining continuous heat treatment furnaces with martempering,
we provide high-quality steel strips with low internal stress, uniform microstructure, and stable precision.
For customers seeking high durability, precise processing, and reliability,
we invite you to try samples or consult with our technical team to experience the advantages of our steel strips firsthand.
