This cast iron can also be processed with threading and small hole tapping even at high hardness around HB430!
The "FCD1200 QT Gear" is manufactured by adding heat treatment (QT) to FCD800. It has high strength, with outstanding fatigue strength in the black skin area. It excels in wear resistance and achieves excellent surface roughness in the cutting process. In the case of austempered ductile iron (ADI), machining is already difficult at a hardness of HB320, but with this cast iron, even at a high hardness of around HB430, gear cutting and small hole tapping are possible. 【Features】 ■ High strength with outstanding fatigue strength in the black skin area ■ High yield ratio of 90% (yield strength = over 1080 MPa) ■ No grinding process required (no heat treatment after cutting) ■ Excellent wear resistance ■ Superior damping ability (reduced operating noise compared to steel) *For more details, please refer to the PDF document or feel free to contact us.
