AISI 1020 / S20C

Common trade references: AISI/SAE 1020, JIS S20C

Stock range: 6mm - 660mm

General-purpose low carbon steel used where good machinability, simple fabrication, and economical cost matter more than very high strength or wear resistance.

Key Characteristics

• Good machinability for general turning and milling
• Better formability and weldability than
medium/high-carbon grades
• Suitable for shafts, pins, spacers, simple machine
parts, and fabrications
• Can be surface hardened in some

Typical Uses

Shafts, pins, studs, general machine parts, fixtures,
bushes, and fabricated components.

Supply / Processing Notes

Usually chosen for easy machining and fabrication.
Where higher strength or wear resistance is needed,
customers typically move to S45C / 1045, 4130, or
4140.
