![]() ![]() You are comparing one alloy (CS) with Elemental Iron which is not what makes your (CI) pan.Ĭast Iron has more Carbon which makes it a worse conductor than Carbon Steel. "Carbon Steel has a thermal conductivity of 0.51 W/cmK"īoth Cast Iron and Carbon Steel are alloys of Iron with Carbon and impurities. "Iron has a thermal conductivity of 0.8 W/cmK" However, cast iron is better at distributing the heat throughout the pan while carbon steel will have more significant hot/cold spots during the initial stages of heating. What is all boils down to is that both cast iron and carbon steel heat up quickly and evenly after a significant amount of time on the burner. It takes less time to heat up a carbon steel pan, but the heat doesn't distribute too well throughout the pan. However, carbon steel has a lower relative thermal conductivity, so it will heat up more unevenly. Carbon steel pans are 1/3 to 2/3 the mass of cast iron pans, so they require less energy to heat up. Per unit mass, both pans will require the same amount of energy to heat up.īurners only apply heat to the bottom of the pan unless they are induction cooktops, so the heat source is already "uneven" (especially if it uses coils/a ring of fire). So why does carbon steel have terrible heat distribution compared to cast iron? Cast iron is a better conductor of heat, so it can distribute thermal energy more evenly/rapidly throughout the pan than carbon steel can. Both have roughly the same densities (7.87 g/cm^3). Their specific heats are roughly the same, so it takes roughly the same amount of heat energy to raise their temperatures. Iron has a specific heat of 0.45 J/gK while carbon steel has a specific heat of 0.48 J/gK. Iron is a better conductor of heat and should distribute heat more evenly. Iron has a thermal conductivity of 0.8 W/cmK while carbon steel has a thermal conductivity of 0.51 W/cmK. Let's work with iron and carbon steel for comparative purposes. But relative thermal conductivity, specific heats, and material density will tell a different story. "Heat distribution" and "conductivity" are the same, but I meant to say "heats unevenly but also heats up quickly". Make sure to include a link!
