1045 SBQ Hot Rolled Bar

1045 sbq bar

Characteristics

1045 bar is a medium carbon steel bar that offers greater strength and hardness as compared to the low carbon grades.  Formability and weldability of 1045 is fair when using accepted shop practices.  While machinability is good, this grade responds very well to forging and heat treating.

Applications

Typical applications of 1045 SBQ bar include gears, shafts, axles, bolts, studs, crane wheels, and machine parts.
