About 1018 steel

1018 cold finished is the machining steel of the rack. It drills, taps, turns, and mills cleanly, holds its size, and comes with a smooth, accurate surface instead of mill scale. It's low carbon, so it welds easily but won't through-harden: that's the trade, easy to work but not a wear part. Brackets, pins, bushings, spacers, and keyed shafts are 1018 territory.

Read the full 1018 vs A36 vs 1045 steel guide

What is 1018 steel used for?

Machined parts that meet a cutting tool: pins, bushings, spacers, keyed shafts, brackets. It machines clean and holds size. For parts that carry real load or wear, step up to 1045.

Can you harden 1018?

Not through its thickness, since it's low carbon. You can case-harden the surface, but if a part needs real hardness or heat treatment, 1045 is the grade you want.
