Steel DC06-CR vs DC06 +Z
Steel · DC06 temper comparison
DC06-CR and DC06 +Z are two conditions of the same steel grade, DC06: CR (cold rolled) versus +Z (hot-dip galvanized extra-deep-drawing sheet). The chemistry is identical, so every difference below comes from the condition. Both yield at about 150 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (cold rolled versus hot-dip galvanized extra-deep-drawing sheet). DC06-CR runs hotter in service (250°C vs 200°C continuous). On the shop floor, DC06-CR welds better (excellent vs very good).

DC06-CR vs DC06 +Z: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

DC06-CR vs DC06 +Z — frequently asked
What is the difference between DC06-CR and DC06 +Z?
DC06-CR and DC06 +Z are two conditions of the same steel grade, DC06: CR (cold rolled) versus +Z (hot-dip galvanized extra-deep-drawing sheet). The chemistry is identical, so every difference below comes from the condition. Both yield at about 150 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (cold rolled versus hot-dip galvanized extra-deep-drawing sheet).
Which condition does FabDigit quote by default, CR or +Z?
CR is the default DC06 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, DC06-CR or DC06 +Z?
DC06-CR, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for DC06 +Z; for welding the order is DC06-CR first (excellent, 95/100) then DC06 +Z (very good, 80/100).
