The use of high Cr iron (C- 2 % to 3 %, Cr- 15 % to 20 %) and later on high Cr steel (C- 1 % to 2 %, Cr- 10 % to 15 %) for rolls resulted into the use of new materials with high wear resistance. In 1985, high speed tool materials have found use for rolls. These materials have evolved as the so-called 'semi tool steel grades'.

High carbon steel typically contains around 0.61% to 1.5% carbon content, resulting in strong, brittle, and hard steel. To improve its wear resistance, it is taken through appropriate heat treatment. Besides being used for high strength wires and springs, it is a useful material for producing shock-absorbing machinery. B) Medium Carbon Steel
Chemical Composition of Steel. Steel is an alloy of iron and other elements. Some elements are intentionally added to iron for the purpose of attaining certain specific properties and characteristics. Other elements are present incidentally and cannot be easily removed. Such elements are referred to as "trace" or "residual" elements.
