G10160, commonly referred to as SAE 1016, is a low-carbon non-alloy steel that belongs to the AISI-SAE 10xx series of carbon steels. It is widely used in the automotive, mechanical manufacturing, and general structural material sectors due to its moderate strength, good plasticity, and machinability.

1. Chemical Composition (Mass Fraction, %)

• Carbon (C)：0.13–0.18

• Manganese (Mn)：0.60–0.90

• Silicon (Si)：≤ 0.10

• Sulfur (S)：≤ 0.050

• Phosphorus (P)：≤ 0.040

2. Material Properties

• Mechanical Properties (Cold Drawn or Hot Rolled State, Unheat-treated)

• Tensile Strength (σb)：370–500 MPa

• Yield Strength (σs)：≥ 250 MPa

• Elongation (δ5)：≥ 28%

• Brinell Hardness (HB)：111–149

• G10160 exhibits good ductility and relatively low yield strength in the annealed or hot-rolled state, making it suitable for forming operations.

3. Heat Treatment Characteristics
Due to its low carbon content, G10160 has poor hardenability and is generally not used for applications requiring high-strength quenching. Common heat treatment methods include:

• Normalizing: Improves microstructure uniformity and is suitable for subsequent cold processing.

• Annealing: Reduces hardness and improves machinability.

• Cold Drawing: Increases strength and dimensional accuracy but reduces plasticity.

4. Machining and Welding Performance

• Machinability：Good

• Cold Forming Ability：Excellent

• Weldability：Good (requires attention to cold cracking)

• Surface Treatment Compatibility：Can be galvanized, painted, etc.

• G10160 is suitable for machining (such as turning and milling) and can be welded using conventional methods. Preheating before welding is recommended to reduce the risk of cracking.

5. Standards and Corresponding Grades

• SAE/AISI：1016

• UNS：G10160

• ASTM：A29 / A510, etc.

• DIN/EN：C15E (Close)

• JIS：S15C (Similar)

• GB：15 Steel (Approx.)

• Note: While similar grades in different standards have comparable compositions, actual composition and performance should be verified for critical applications.

6. Typical Applications

• Automotive Parts: Such as pin shafts, bushings, piston pins, etc.

• Mechanical Structural Parts: Such as gear blanks, forgings, bolts, etc.

• Welded Structures: Such as light-duty brackets, housings, etc.

• Fasteners and Hardware: Applications requiring moderate strength and good machinability.

7.Conclusion
G10160 is a typical low-carbon structural steel, offering advantages such as low cost, good machinability, and excellent weldability. It is ideal for applications requiring moderate strength and high machining process requirements, such as in mechanical structures and automotive components. If higher strength or wear resistance is needed, it is recommended to consider steels with higher carbon content or alloying elements, such as 1045 or 4140.
