Product Description

High Hardness AISI SA4140 Carbon Steel Optical Shaft Straight Chrome 4150 Plated Piston Rod BV Certified Round Standard Shape Bar Factory

Product Description

AISI SA4140 steel is a low-alloy, medium-carbon chromium-molybdenum steel known for its excellent strength, toughness, and hardenability. When formed into rods, it becomes a versatile material widely used in industrial and engineering applications.
Chemical Composition (Typical, % by Weight)
Carbon (C): 0.38 - 0.43%
Chromium (Cr): 0.80 - 1.10%
Molybdenum (Mo): 0.15 - 0.25%
Manganese (Mn): 0.75 - 1.00%
Silicon (Si): 0.15 - 0.35%
Phosphorus (P): Maximum 0.035%
Sulfur (S): Maximum 0.040%
Mechanical Properties (Annealed and Heat-Treated)
Property Annealed Condition Heat-Treated (Tempered)
Tensile Strength 655 - 795 MPa (95,000 - 115,000 psi) 1,035 - 1,380 MPa (150,000 - 200,000 psi)
Yield Strength 415 MPa (60,000 psi) minimum 860 MPa (125,000 psi) minimum
Elongation (in 50 mm) 25% minimum 12 - 18%
Hardness (Brinell) 197 maximum 28 - 32 HRC (typical)
Modulus of Elasticity ~200 GPa (29,000 ksi) ~200 GPa (29,000 ksi)
Density 7.85 g/cm³ (0.284 lb/in³) 7.85 g/cm³ (0.284 lb/in³)
Key Characteristics
Hardenability: Responds well to heat treatment (quenching and tempering), allowing for customization of strength and toughness.
Weldability: Can be welded using most methods, though preheating and post-weld annealing are recommended to prevent cracking.
Machinability: Good in the annealed state; becomes more challenging after heat treatment due to increased hardness.
Wear Resistance: Excellent when heat-treated, making it suitable for high-stress, abrasive environments.
Common Applications of 4140 Steel Rods
Automotive parts (axles, crankshafts, gears)
Industrial machinery components (shafts, bolts, studs)
Oil and gas equipment (drill collars, connectors)
Tooling and die components
Structural parts requiring high strength-to-weight ratios
4140 steel rods are valued for their balance of strength, ductility, and cost-effectiveness, making them a go-to material for demanding engineering applications.
