Steel Silicon Steel CRGO vs Silicon Steel Hot Rolled
Steel · Silicon Steel temper comparison
Silicon Steel CRGO and Silicon Steel Hot Rolled are two conditions of the same steel grade, Silicon Steel: CRGO (cold-rolled grain-oriented (Goss texture), fully processed) versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Silicon Steel Hot Rolled is the stronger of the two: tensile strength 500 MPa (72.5 ksi) against 380 MPa (55.1 ksi) for Silicon Steel CRGO, about 32% more. Silicon Steel Hot Rolled is the more ductile: elongation 22% versus 8% for Silicon Steel CRGO, and Silicon Steel CRGO is harder (180 HB vs 160 HB). Silicon Steel Hot Rolled is stiffer (205 GPa vs 130 GPa) and Silicon Steel Hot Rolled runs hotter in service (250°C vs 200°C continuous). On the shop floor, Silicon Steel Hot Rolled machines more easily (fair vs poor) and Silicon Steel Hot Rolled welds better (good vs fair).
Silicon Steel Hot RolledChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Silicon Steel CRGO vs Silicon Steel Hot Rolled: 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 CRGO vs Silicon Steel Hot Rolled — frequently asked
Is Silicon Steel Hot Rolled stronger than Silicon Steel CRGO?
Yes. Silicon Steel Hot Rolled has a typical tensile strength of 500 MPa (72.5 ksi) against 380 MPa (55.1 ksi) for Silicon Steel CRGO — about 32% more.
Which condition does FabDigit quote by default, CRGO or Hot Rolled?
Annealed is the default Silicon Steel condition in the FabDigit quote flow (neither CRGO nor Hot Rolled). 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, Silicon Steel CRGO or Silicon Steel Hot Rolled?
Silicon Steel Hot Rolled. Its machinability rates fair (45/100) against poor (32/100) for Silicon Steel CRGO; for welding the order is Silicon Steel Hot Rolled first (good, 55/100) then Silicon Steel CRGO (fair, 35/100).
