50CrV4 Gade in 320mm Diameter 50HF Requirement 51CrV4 Spring Steel Round Bar
AISI 6150 steel is chromium vanadium type spring steel. It's a similar alloy steel to 5150 steel with small, but effective, vanadium addition, to import greater hardness. AISI steel 6150 has low distortion properties and is easily heat treated. The SAE 6150 steel grade is suitable for oil hardening and tempering

4: 6150 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction,
hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be
different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
