ELC steel; ELC (Extra Low Carbon) Steels

Steel with very low carbon content (generally less than 100 ppm).

IF steel; IF (Interstitial Free) Steels

Very low-carbon steel with Ti and/or Nb addition trapping all carbon; the ferritic matrix can then be considered virtually free of residual carbon in solid solution.

HSLA steel; HSLA (High Steel Low Alloyed) Steels

Steel with low carbon and alloying element content; carburizing elements (Nb, Ti, V) are added to produce a fine, dispersed precipitation that contributes to steel hardening, either directly or by limiting grain size.

BH steel; BH (Bake Hardening) Steels

Very low-carbon steel in which a fraction of carbon is left in solution after continuous annealing. The carbon...
