CASE-HARDENING STEEL

Commonly used to enrich the surface carbon content of steel that case hardening provides. This is intended to produce a high-hardness, wear-resistant surface supported by a tenacious core.

HEAT TREATABLE STEEL

Heat-treatable steels are in the mechanical construction steel range. They are characterized by carbon content usually in excess of 0.25%, and may or may not be alloys.
Heat-treatable steels are used to fabricate parts that require a combination of strength and tenacity, with relatively uniform values throughout the cross section or down to a certain depth. These properties are attained by means of quenching and tempering, which comprise the heat-treatment process.

CARBON STEEL

Carbon steel types include low, medium and high carbon content steels whose chemical composition is defined in broad ranges. Low-carbon steel has 0.30% or less carbon; medium-carbon steel has 0.30%-0.60%, and high-carbon steel has 0.60%-1.00% carbon content.
