In the 1920s, the UK relied on pipes made from gray iron vertically cast. Around this time, gray cast iron that was spun also came into use, and the utilization of these pipes would continue through the 1960s. By the 1960s, another transition occurred to ductile cast iron. Why has ductile cast iron come to dominate the industry?
