Spheroidal graphite cast iron - spheroidal graphite cast iron

…When the activity of oxygen contained in this cast iron is reduced by using a deoxidizer such as magnesium, graphite precipitates in a spherical shape, eliminating the variation in material strength and creating ductility. This is called spheroidal graphite cast iron. By changing the cooling rate and other heat treatment conditions, the structure can be made into pearlite and graphite, increasing the strength. …

Japanese:

…この鋳鉄に含まれる酸素の活量をマグネシウムなどの脱酸材を用いて下げると,黒鉛が球状に析出し,材料強度のばらつきがなくなり,延性が生じてくる。これを球状化黒鉛鋳鉄という。冷却速度などの熱処理条件を変えることにより,組織をパーライトと黒鉛にして強度を上昇させることもできる。…
