6150 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
Typical Uses
Typical applications include:
  • Arbors
  • Heavy Machinery Parts
  • Gears
  • Shafts
  • High Strength Studs
  • Spindles

6150 Hot Rolled Annealed Steel

Alro stocks AISI 6150 annealed hot rolled (HR) steel, This grade of steel is an electric furnace melt of chrome vanadium steel possessing characteristics that include: oil-hardening, high resistance to vibratory stress, standard deformation, medium hardness, high torque strength and bright polish.

More About Grade 6150 Steel
6150 steel is similar to 5150. However, the addition of vanadium gives the 6150 steel greater hardness. AISI 6150 has low distortion properties and accepts heat treating easily. Welding may be done, but the material requires proper preheating and post weld stress relieving.
