Short answer: Cast iron is usually a separate grade from HMS because it is brittle, has a different composition and is used in foundries rather than steel mills, so it is often priced differently and may be refused in a steel load, which is why you should sort cast iron items such as engine blocks, old radiators and bath tubs away from your heavy steel.
