1.1 ,This specification covers pearlitic malleable iron castings for general engineering usage at temperatures from normal ambient to approximately 750 ,°,F [400 ,°,C].
1.1.1 ,For continuous service at temperatures up to 1200 ,°,F [650 ,°,C], design factors should be incorporated to compensate for possible property changes, as demonstrated by Marshall and Sommer2 and by Pearson.3
