... resistance because of its higher hardness, whereas CA-15 would likely be the most economical of the three. All of these alloys require heat treatment after casting. Tempering heat treatments should be selected that yield tensile strengths in the range of 690 to 790 MPa (100 to 115 ksi). Heat treatments...
