Steel CRGO Annealed vs CRGO-HiB
Steel · CRGO temper comparison
CRGO Annealed and CRGO-HiB are two conditions of the same steel grade, CRGO: Annealed versus HiB (high-permeability grain oriented). The chemistry is identical, so every difference below comes from the condition. Both yield at about 305 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus high-permeability grain oriented). CRGO Annealed is the more ductile: elongation 10% versus 8% for CRGO-HiB.

CRGO Annealed vs CRGO-HiB: 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.

CRGO Annealed vs CRGO-HiB — frequently asked
What is the difference between CRGO Annealed and CRGO-HiB?
CRGO Annealed and CRGO-HiB are two conditions of the same steel grade, CRGO: Annealed versus HiB (high-permeability grain oriented). The chemistry is identical, so every difference below comes from the condition. Both yield at about 305 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus high-permeability grain oriented).
Which condition does FabDigit quote by default, Annealed or HiB?
Annealed is the default CRGO 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 welds better, CRGO Annealed or CRGO-HiB?
CRGO Annealed. Its weldability rates poor (30/100) against poor (25/100) for CRGO-HiB.
