Our world-leading R&D system is pioneering new steel bar and wire rod technologies.

Development of high performance steel bars     Machining process analysis technology     Functional/structural evaluation technologies

We propose total solutions ranging from material development to products.

JFE Steel Research Laboratory is one of the world's largest research laboratories (in the steel industry).

Development of high performance steel bars

We improved the fatigue strength of components by integrating surface technologies-such as carburizing, quenching and induction quenching-with steel composition design technologies in order to offer products with optimally controlled metallic structures that meet customers' needs.
	Fine austenite steel produced with high frequency induction quenching technology shows excellent delayed fracture strength (as measured by constant-load delayed fracture testing equipment).

Machining process analysis technology

pecialty steel is machined and thermally treated by customers before use. We work to develop steel products that can be efficiently machined and thermally treated by customers. In addition, we work to develop steel products that do not require thermal treatment for the purpose of saving energy. Furthermore, we promote the elimination of the thermal refining process from the manufacturing processes of steel bars in order to contribute to the protection of the global environment.
