Steel Silicon Steel Cold Rolled vs Silicon Steel CRGO
Steel · Silicon Steel temper comparison
Silicon Steel Cold Rolled and Silicon Steel CRGO are two conditions of the same steel grade, Silicon Steel: Cold Rolled versus CRGO (cold-rolled grain-oriented (Goss texture), fully processed). The chemistry is identical, so every difference below comes from the condition. Silicon Steel Cold Rolled is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 320 MPa (46.4 ksi) for Silicon Steel CRGO, about 81% more; tensile strength follows at 650 MPa (94.3 ksi) vs 380 MPa (55.1 ksi). In exchange, Silicon Steel CRGO is the more ductile: elongation 8% versus 5% for Silicon Steel Cold Rolled, and Silicon Steel Cold Rolled is harder (222 HB vs 180 HB). Silicon Steel Cold Rolled is stiffer (205 GPa vs 130 GPa) and Silicon Steel CRGO runs hotter in service (200°C vs 150°C continuous).
Silicon Steel Cold RolledChoose it when strength drives the design.
Silicon Steel CRGOChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Silicon Steel Cold Rolled vs Silicon Steel CRGO: 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.

Silicon Steel Cold Rolled vs Silicon Steel CRGO — frequently asked
Is Silicon Steel Cold Rolled stronger than Silicon Steel CRGO?
Yes. Silicon Steel Cold Rolled has a typical yield strength of 580 MPa (84.1 ksi) against 320 MPa (46.4 ksi) for Silicon Steel CRGO — about 81% more. Tensile strength is 650 MPa (94.3 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, Cold Rolled or CRGO?
Annealed is the default Silicon Steel condition in the FabDigit quote flow (neither Cold Rolled nor CRGO). 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.
When should I choose Silicon Steel Cold Rolled over Silicon Steel CRGO?
Pick Silicon Steel Cold Rolled when strength drives the design. Pick Silicon Steel CRGO when the part is bent, formed or impact-loaded, or when the part sees heat.
