1. Key Properties:
High Carbon Content: SAE 1060 is a high-carbon steel with approximately 0.60% carbon content, which provides higher strength and hardness compared to medium-carbon steels.
Excellent Hardening Potential: Due to its higher carbon content, SAE 1060 can achieve higher hardness and strength when heat treated, making it ideal for applications requiring wear resistance and toughness.
Good Wear Resistance: This steel offers good wear resistance, particularly when quenched and tempered, making it suitable for components subjected to high friction and abrasive conditions.
Moderate Toughness: While SAE 1060 offers good strength, its toughness is somewhat reduced compared to lower-carbon steels, so it may not be suitable for highly impact-resistant applications unless it is heat treated.
Weldability: SAE 1060 is more difficult to weld than lower-carbon steels, and preheating is usually necessary for thicker sections to reduce the risk of cracking.
Machinability: The machinability of SAE 1060 is moderate to poor, especially in its hardened state. It requires good-quality cutting tools for machining.
2. Applications/Industries:
Automotive: SAE 1060 is commonly used for manufacturing automotive components that require high strength, such as gears, shafts, springs, and camshafts.
Heavy Machinery: It is used in heavy machinery for parts like axles, gears, and shafts, which require high wear resistance and moderate strength.
Manufacturing: Due to its hardness and wear resistance, SAE 1060 is used in manufacturing parts like cutting tools, dies, and machine components that are subject to high stress.
Agricultural Equipment: SAE 1060 is used for high-strength components in agricultural machinery such as drive shafts and components exposed to heavy wear.
Tooling: SAE 1060 can be used in tooling applications such as tool blades, punches, and dies that require hardness and wear resistance.
3. Certifications/Standards:
SAE J403: SAE 1060 conforms to the SAE J403 standard for high-carbon steels, ensuring it meets the required chemical composition and mechanical properties.
ASTM A519: This standard applies to seamless carbon and alloy steel mechanical tubing, which is relevant for SAE 1060 seamless pipes.
ISO 9001: Quality management system certification.
