Product Description

 Factory Price ASTM 6150 GB 50CrVA Spring Steel Forged Alloy Steel Round Bar


 1: 6150 steel introduction

    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.

3: 6150 steel chemical composition


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.

Application6150 spring steels are used for heavily stressed machinery parts including shafts, gears, pinions and also in hand tool components. ASTM 6150 steel is also widely in the motor vehicle industry AISI 6150 is suitable for many general engineering applications that require high tensile strength and toughness


6. ASTM 6150 Steel Heat Treatment


    1200-1250F (650-675oC), equalize.


    1100-1300F (595-740oC), hold 2 hours, air cool. As with 5150 alloy, the microstructure for this 6150 alloy steel to give optimum machinability is one of coarse lamellar pearlite to coarse spheroidite.


    A nominal normalizing temperature for the 6150 spring steel is 1650oF (900oC.) This treatment is followed by air cooling.


    Best done warm 400-800F (205-425oC).

High Heat:

    1550-1650F (845-900oC), soak 10 to 30 minutes. For vacuum hardening, use the high side of the high heat range and soak times.


    Oil quench to hand warm, 150F (65oC). Temper SAE 6150 steel immediately. Note vacuum furnaces must have oil quench capability.


    Tempering at 400-1200 (205-650oC) for 1 hour per inch (25mm) of thickness at temperature is recommended. (2 hours min.). Air cool to room temperature. Tempering of the AISI 6150 grade steel will be between 400-600°C for most applications.


7: Delivery condition

    For hot rolled bar, usually the delivery condition is hot rolled, annealed, Black surface.
    For hot rolled sheet, usually the delivery conditon is hot rolled, annealed, black surface.
