1010 vs 1012 — frequently asked

What is the difference between 1010 and 1012?

Steel 1010 and 1012 are both steel grades, both low carbon steel. Both yield at about 180 MPa — strength does not separate them.

Which is cheaper, 1010 or 1012?

Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1010 or 1012?

1012, by a small margin. Both rate fair for machinability — 50/100 against 42/100 for 1010.
