Mild steel splits into CR, HR and HR P&O, stainless into 304 and 316,
and aluminum into 5052 and 6061, so no thickness carries a grade it is
not sold in. Gauge thicknesses use MaterialLedger's decimals, which
also corrects stainless gauges that used carbon-steel values.
Every thickness gets a 60 degree line lead-in (0.15", longer from
1/4" up) and a 0.1" lead-out, with no lead-out on inside cuts, a 0.75
cut-off overtravel and every catalog plate size up to 72x144.
