2.Carbon Steel
Carbon steel is a steel with carbon content up to 2.1% by weight.
The term "carbon steel" may also be used in reference to steel which is not stainless steel; in
this use carbon steel may include alloy steels.
As the carbon percentage content rises, steel has the ability to become harder and stronger
through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a
higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers
the melting point.
AISI classification
Carbon steel is broken down into four classes based on carbon content:
Low-carbon steel
0.05 to 0.30% carbon (plain carbon steel) content.
Medium-carbon steel
Approximately 0.3–0.6% carbon content.Balances ductility and strength and has good wear
resistance; used for large parts, forging and automotive components.
High-carbon steel
Approximately 0.60 to 1.00% carbon content.Very strong, used for springs, edged tools, and high-
strength wires.
Ultra-high-carbon steel
Approximately 1.25–2.0% carbon content.Steels that can be tempered to great hardness. Used for
special purposes like (non-industrial-purpose) knives, axles or punches. Most steels with more than
2.5% carbon content are made using powder metallurgy.
3.Carbon Steel Flange Packaging
Carbon Steel Flanges are widely used in various industries including petrochemical, oil and gas,power
generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing,
textiles and others. All our Carbon Steel Flange are manufactured in accordance with international
standards. Carbon Steel Flanges are packaged to ensure that there is no damage during transit.In case
of exports, standard export packaging is done in wooden cases. All Carbon Steel Flanges are marked
with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make custom
marking on Carbon Steel Flanges.
