This part of ISO 4948 defines steel and gives 2.0 % carbon as the usual dividing line between steel and cast iron. The classification based on the specified values for the ladle analyses of the elements given in the table.
Abstract
Overview
ISO 4948-1:1982 is an internationally recognized standard published by the International Organization for Standardization (ISO) that establishes a systematic classification of steels based on their chemical composition. This part of the series specifically differentiates between unalloyed (plain carbon) and alloy steels. The classification framework hinges on the chemical element content determined by ladle analysis, with a critical threshold of 2.0% carbon content serving as the dividing line between steel and cast iron.
