Product Description

AISI 9310 Bearing Steel Alloy Steel
9310 steel is a nickel-chromium-molybdenum alloy steel known for its high hardenability, toughness, and fatigue strength. It is commonly used in applications requiring high core strength, such as gears, shafts, and aerospace components.

Chemical Composition:
Carbon (C): 0.08-0.13%
Manganese (Mn): 0.45-0.65%
Silicon (Si): 0.20-0.35%
Nickel (Ni): 3.00-3.50%
Chromium (Cr): 0.80-1.10%
Molybdenum (Mo): 0.08-0.15%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%

Properties:
·Hardenability: 9310 steel exhibits high hardenability, allowing for deep and uniform hardness penetration during heat treatment.
·Toughness: It possesses excellent toughness, making it resistant to impact and shock loads.
·Fatigue Strength: The alloy has good fatigue strength, making it suitable for applications subjected to cyclic loading.
·Machinability: 9310 steel has fair to good machinability in the annealed or normalized condition.
·Weldability: It can be welded using conventional welding methods, but preheating and post-weld heat treatment may be necessary to avoid cracking.

Heat Treatment:
·Annealing: Heating to 815-845°C, followed by slow cooling in the furnace to relieve internal stresses and improve machinability.
·Normalizing: Heating to 870-930°C, followed by air cooling to refine the grain structure and improve mechanical properties.
·Hardening: Austenitizing at 855-870°C, followed by oil quenching to achieve the desired hardness.
·Tempering: Tempering at 150-200°C to achieve the desired balance of hardness and toughness.

Processing
·9310 steel can be readily machined and welded, making it suitable for various manufacturing processes.

Comparisons
9310 steel is often compared to other alloy steels such as 8620 steel due to its similar composition and properties, but with higher nickel content, offering improved hardenability and strength.

Applications:
·Gears and gearboxes
·Aircraft components (landing gear, gearbox components)
·Transmission components
·High-strength fasteners
·Automotive parts (driveshafts, axles)
