17CrNiMo6-7 Alloy Steel Round Bars

17CrNiMo6 Steel Round Bars material properties are high tensile strength, hardness and wear and tear resistance. 17CrNiMo6 hardness is extreme.  Parag Steel Corporation provides 17CrNiMo6 round bars, forged bars, bright bars and other sizes of premium quality.

17CrNiMo6 Alloy Steel Round Bars is commonly used in applications requiring high strength and toughness, such as gears, shafts, crankshafts, and other heavy-duty components subjected to high loads and stresses.

Chemical Composition:

Mechanical Properties (Typical values for quenched and tempered condition):

• Tensile Strength: 1000 - 1300 MPa
• Yield Strength (0.2% offset): 800 - 1100 MPa
• Elongation: 10 - 14%
• Reduction of Area: 45 - 55%
• Impact Toughness (Charpy V-notch): 40 - 60 J/cm²

Physical Properties:

• Density: 7.85 g/cm³
• Melting Point: Approximately 1420°C (2588°F)

Heat Treatment:

• Annealing: Heat to 850-890°C (1562-1634°F), furnace cool at a rate not exceeding 30°C (54°F) per hour to 650°C (1202°F), then cool in air.
• Normalizing: Heat to 870-920°C (1598-1688°F), air cool.
• Quenching: Oil quench from 850-880°C (1562-1616°F) or water quench from 830-860°C (1526-1580°F), followed by tempering.
• Tempering: Temper at a desired temperature depending on the desired properties. Typical tempering temperatures range from 550-650°C (1022-1202°F) for achieving a balance of strength and toughness.
