C30 carbon round bar
Solid Round Bar Products Description
C30 round bars are usually supplied in normalized or hot rolled state. C30 carbon steel bars have good machinability and weldability, while C30 hot rolled bars also have high impact properties.
The C30 hot rolled bar alloy also contains a large amount of manganese, phosphorus and sulfur. Carbon steel C30 bars are mainly used in general engineering fields, especially in machinery and automobile parts manufacturing.
