Carbon Cast Steel
|
 |
Carbon Cast Steel has a low alloy content and is annealed to produce a tough material which has low thermal sensitivity.
The structure changes from ferrite and pearlite in the low carbon grades to wholly pearlitic in the high carbon qualities. Hardness and wear resistance increase with carbon content.
The high toughness and thermal shock resistance make Carbon Cast Steel very suitable for heavy duty applications such as primary mills and the roughing of heavy sections.
The lower carbon grades have good weldability.
