A new modification of an economical casting material is presented for use in the intermediate temperature range, which is considered to be 800 to 1300 F. An illustration is given of two large castings actually produced for the 1500-hp ATAC regenerative gas turbines engine. Comparisons are made with other materials, giving information stress-rupture at various temperature levels and some cost information. Also included are design suggestions for better utilization of foundry techniques.
