AISI 1020

Typical analysis

C	Mn	P	S
0.17 - 0.24	0.25 - 0.60	max 0.04	max 0.05

A general purpose mild steel, low-carbon machinery steel, having good over-all mechanical properties. Easily machinable and weldable. Suitable for heat treatment and ideal for carburizing.

Typical applications

General purpose structural and miscellaneous non-critical applications, general engineering parts, shafts, agricultural implements, hubs, so on.

Mechanical properties

Machinability

AISI 1020 in the as supplied condition has a machinability rating of 72% based on AISI 1212 as 100%. Average surface cutting speed is 120 feet per minute.

Weldability

AISI 1020 is easily welded by all welding processes. The resultant welds and joints are of extremely high quality. Welding rod to be used depends upon the thickness of section, design, service requirements and so on.
