HR 1018 SBQ Bar

Characteristics

HR 1018 SBQ bar is a low carbon steel bar that offers good formability, wedability and machinability.  Since it has higher manganese content than commercial quality and 1020, it offers better carburizing properties.  The mechanical properties of HR 1018 SBQ bar are higher than commercial quality. 

Applications

Typical applications include gears, pins, studs, bolts, farm implements, industrial machinery & other similar applications.
