High Carbon Steel Materials Materials Library

If you continue increasing the carbon content of steel beyond about 2%, it eventually becomes cast iron, the material famously used in Le Creuset cookware, a much harder, denser and more brittle metal as a result of its impurities. The carbon in this sample of steel strengthens it and gives it the ability to harden by heat treatment.

Carbon Alloy Steels Technical Information MSC

Carbon Alloy Steels Technical Information. Steel parts that require no special properties or heat treatment often are madeof this type of steel. Alloy steels have additional alloying elements and carbon added to improve the mechanical properties and hardenability. The alloying elements allow the steel to form carbon or alloy carbides that improve wear and/or toughness when heat treated.

Mild Steel an overview ScienceDirect Topics

Although the two-phase ferrite-cementite microstructures of upper and lower bainite form readily in medium-carbon steels, in low-carbon steels under similar cooling conditions, bainitic-like microstructures without cementite may form . Carbon is rejected from ferritic laths, but steel carbon content is too low to cause cementite formation.

Improving Wear with a Novel Heat-Treatment Method 2019

Jan 11, 2019Transforming the case of low-carbon steel to a fully martensitic and wear-resistant structure is commercially performed with the carbonitride and oil-quench process. This process, however, does not always optimize wear characteristics and is highly dependent on the grain size, the specific percentage of elements making up a particular heat of

A fundamental point to be highlighted is the fact that carbon must be kept as low as possible. Carbon, a useful interstitial element normally used to harden metal material by applying fast cooling thermal treatments as like Tempering Annealing, is extremely dangerous when preparing inox steels because of it's tendency to make carbures.
