Metallurgy Matters: Carbon content, steel classifications ...

Aug 28, 2003· Most steel contains less than 0.35 percent carbon. To put this in perspective, keep in mind that's 35/100 of 1 percent. Now, any steel in the 0.35 to 1.86 percent carbon content range can be hardened using a heat-quench-temper cycle. Most commercial steels are classified into one of three groups: Plain carbon steels.
