Quenched and tempered

Strength meets responsibility

Our quenched and tempered process is engineered for performance and care. Through precise heat treatment, we refine the steel’s microstructure to deliver exceptional strength, durability, and fatigue resistance - all while applying rigorous safety and environmental controls. We quench under carefully controlled conditions to generate a hardened (martensitic) structure, and then temper to optimize toughness, relieve stresses, and reduce brittleness. This balance ensures that our wires can endure demanding service without failure. 

Responsible operations and reliable performance

We manage quenching media and operations to minimize risk and waste. Our process includes fire safety measures, careful quench monitoring, and responsible disposal or recycling of quench oils and residues. By controlling every heat-treatment step, we reduce property scattering and ensure consistency—even for critical applications. This level of quality is indispensable in sectors like automotive, mechanical engineering, and safety-sensitive components.

Our most recent development is our oil and lead free hardening, currently implemented in our Site in Suzhou, China.

Our capabilities

Patenting for ductility and toughness

Patenting refines the microstructure to improve ductility and toughness and can prepare the wire for additional cold working processes.

Spheroidizing for enhanced formability

Spheroidizing modifies the carbide structure to improve formability, making the wire easier to process in demanding forming applications.

Annealing for flexibility

Annealing softens the material and increases flexibility, supporting efficient manufacturing and improved performance in applications requiring high ductility.
