Automotive Why Don't Engines Use More Steel?

  1. Mar 15, 2017 #1
    Are there any reasons why engines tend to use iron, aluminum, titanium (connecting rods), and even magnesium (engine blocks) components while steel is far less common?

    Because for a lot of reasons iron is a better metal to cast and forge if needed then steel. Also anyone that has heard an engine with a steel block knows the noise it makes doesn't suit the family car.
