Steel TRIP Steel-CR vs TRIP Steel TRIP590
Steel · TRIP Steel temper comparison
TRIP Steel-CR and TRIP Steel TRIP590 are two conditions of the same steel grade, TRIP Steel: CR (cold rolled) versus TRIP590. The chemistry is identical, so every difference below comes from the condition. TRIP Steel-CR is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 400 MPa (58 ksi) for TRIP Steel TRIP590, about 23% more; tensile strength follows at 820 MPa (119 ksi) vs 630 MPa (91.4 ksi). In exchange, TRIP Steel TRIP590 is the more ductile: elongation 30% versus 25% for TRIP Steel-CR, and TRIP Steel-CR is harder (242 HB vs 190 HB).
TRIP Steel-CRChoose it when strength drives the design.
TRIP Steel TRIP590Choose it when the part is bent, formed or impact-loaded.
TRIP Steel-CR vs TRIP Steel TRIP590: 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.

TRIP Steel-CR vs TRIP Steel TRIP590 — frequently asked
Is TRIP Steel-CR stronger than TRIP Steel TRIP590?
Yes. TRIP Steel-CR has a typical yield strength of 490 MPa (71.1 ksi) against 400 MPa (58 ksi) for TRIP Steel TRIP590 — about 23% more. Tensile strength is 820 MPa (119 ksi) vs 630 MPa (91.4 ksi).
Which condition does FabDigit quote by default, CR or TRIP590?
CR is the default TRIP Steel 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, TRIP Steel-CR or TRIP Steel TRIP590?
TRIP Steel TRIP590, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for TRIP Steel-CR; for welding the order is TRIP Steel TRIP590 first (good, 68/100) then TRIP Steel-CR (good, 62/100).
