About 1144 steel

1144 is a free-machining medium-carbon steel, often sold as a stress-relieved 'stressproof' bar. It gives you high strength and good machinability without heat treatment, and it stays straight when you machine it because the internal stress is already relieved. Good for shafts, studs, and machined parts that need strength straight off the saw.

Read the full 1018 vs A36 vs 1045 steel guide
Why pick 1144 over 1045?
1144 machines more freely and comes stress-relieved, so it holds straight when you turn or mill it and gives high strength without heat treating. 1045 is the more common medium-carbon bar; 1144 is the one you reach for when machinability and straightness matter.
