Foundry

Introduction

• Steel melts at around 2500F, 1350C, or slightly below pure iron
• Iron melting point - 1540C, 1811K, 2800F
• Cast iron melting point - 1150-1200C, about 300C lower than pure iron
• From [1]:
  • Seel is iron and up to 2.0% carbon without any other alloying elements
  • Above 2.0% C we are dealing with cast iron. Cast iron tends to be brittle, unless it is ductile cast iron.
  • The steel melting point varies between 1540°C and 1400°C, gradually declining with increasing carbon content.
