A low-carbon, cold-rolled steel with good, predictable machinability and good weldability. Not hardenable by through-heat-treat (only case hardening) — a reasonable low-cost default for structural or low-stress machined parts.
These are the preset values this tool starts from — every one is editable in the settings panel once you load a file. They're cncquoter's own defaults, not a market survey.
A plain 40 × 30 × 10mm block in Steel 1018, 3mm stock allowance per side, 2 estimated setups, cncquoter's default shop rate ($95/hr, 25% margin) — computed live by the same cost model at each quantity:
| Quantity | Price / part | Total |
|---|---|---|
| 1 | $127.07 – $211.78 | $127.07 – $211.78 |
| 10 | $14.63 – $24.38 | $146.30 – $243.83 |
| 100 | $3.39 – $5.64 | $338.57 – $564.29 |
This is one fixed sample shape for comparison across materials — your actual part's size, geometry, and setups will change every number here.
