• Carbon (C): ≤ 0.22%

• Manganese (Mn): 1.35% max

• Phosphorus (P): ≤ 0.035%

• Sulphur (S): ≤ 0.035%

• Iron (Fe): Balance

Mechanical Properties:

• Yield Strength: ≥ 355 MPa

• Tensile Strength: 470 – 630 MPa

• Elongation: ≥ 20%

• Hardness: 130 – 170 HB

Key Features:

• High strength-to-weight ratio

• Good weldability and machinability

• Excellent toughness and durability

• Can be used in normalized or as-rolled condition

Applications:

• Shafts, axles, and pins

SAE 1141 is a medium carbon, manganese steel with added sulphur to improve machinability. It is categorized as a free-machining steel, making it ideal for producing precision components with high-speed machining operations. This grade offers a good balance of strength, hardness, and machinability, and can be heat-treated for additional strength and wear resistance.

Chemical Composition (Typical %):

• Carbon (C): 0.37 – 0.45%

• Manganese (Mn): 1.35 – 1.65%

• Phosphorus (P): ≤ 0.040%

• Sulphur (S): 0.08 – 0.13%

• Iron (Fe): Balance

Mechanical Properties (Approximate):

• Tensile Strength: 620 – 760 MPa

• Yield Strength: ~415 MPa

• Hardness (Brinell): 170 – 220 HB (annealed)

• Elongation: 20%

• Density: 7.85 g/cm³

Key Features:

• Excellent machinability due to higher sulphur content

• Good strength and toughness

• Can be hardened and tempered

• Suitable for repetitive machining and production runs

• Not recommended for welding due to sulphur content

Heat Treatment:

• Annealing: 845°C, slow furnace cooling

• Normalizing: 870 – 900°C, air cool

• Hardening: 830 – 860°C, oil quench

• Tempering: 425 – 650°C (depending on desired hardness)

Applications:

• Shafts and axles

• Studs, bolts, and pins

• Machined components and fittings

• Automotive parts and fasteners

• Gears and couplings
