AISI 6150 Spring Steel

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.

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.
