Uncover the Superior Properties of SAE AISI 1020 Steel: Exploring C1020 Carbon Steel Yield Strength and Equivalents
Discover the Excellence of ASTM SAE AISI 1020 Steel
AISI 1020 steel, also renowned as C1020 steel, excels in its cold worked forms (cold rolled or cold drawn). This versatile carbon steel, favored for its excellent machinability and weldability, can be hot rolled or cold drawn, but is typically in turned and polished or cold drawn states. Its low carbon content imparts resistance to induction or flame hardening, making it a staple in various applications.

Reheating (Austenitizing) Procedures
Optimal Reheating (Austenitizing) Temperatures for Hardening SAE 1020 Steel: 760-790 °C (1400-1450 °F). Carburizing Typically Performed at 900 to 925 °C (1650 to 1700 °F).
Expert Guide to Case Hardening
The surface hardening carburization temperature of 1020 carbon steel ranges between 970-955 °C. This process typically utilizes a blend of methane and carrier gas. Following carburization, hardening is often accomplished through direct quenching into water or brine from the carburizing temperature.
Typical Heat Treatment for SAE 1020 Case Hardening
- Carbon Temperature: 900-925 °C (1650-1700 °F), Cooling Method: Water or Caustic.
- Reheat Temperature: 790 °C (1450 °F), Cooling Method: Water or 3% Sodium Hydroxide.
- Carbonitriding Temperature: 790-900 °C (1450-1650 °F), Cooling Method: Oil.
- Temper Temperature: 120-205 °C (250-400 °F). This step is for stress relief and enhancing resistance to cracking, though it is not mandatory.
Typical Forging Temperature
The ideal forging temperature for AISI 1020 mild steel is 1290 °C (2350 °F).
AISI 1020 Carbon Steel Welding
Recommended Preheat and Interpass Temperatures for AISI SAE C1020 Steel:
For thickness ≤50mm (2 in.), a recommended preheat and interpass temperature is above -12 °C (for low hydrogen); 38 °C for non-low hydrogen.
For thickness 50 < t ≤ 100mm, the recommended preheat and interpass temperature is 93 °C (for low hydrogen); 150 °C for non-low hydrogen.
Postweld heat treatment is optional, with a temperature range of 590-675 °C (1100-1250 °F).
