Specialized Heat
Treatment Technology
Our greatest strength lies in our proprietary special heat treatment technology. Processes like bainite treatment, which demand extreme strength and wear resistance, are highly specialized and rare in Korea.
Yet, based on our years of know-how and automation systems, HANSUNG has built its own in-house bainite heat treatment capabilities. This unique expertise is widely recognized for its quality and reliability by both domestic and international clients.
We will continue to grow as a technology-driven company that delivers tailored solutions for a wide range of industries, beyond automotive, through precision engineering, automation, and advanced heat treatment capabilities.
