The stainless tube produced by the heat treatment of Handuk R-FECO is used for automobile equipment which requires weight lightening and corrosion resistance, for heat exchanger equipment which requires corrosion resistance and thermal resistance, for medical appliances/semiconductor industry which requires high-cleanliness.

The stainless steel pipe heat treatment furnace of Handuk R-FECO largely reduced cost price by installing embedded burner which is a device for high-efficient of waste heat and gained DNV-GL certification for operating temperature distribution evenly. Through these works, it is also used in heat treatment that requires special attributes such as austenite, duplex etc.
