Steel TRIP1000-CR vs TRIP1000 CR+BH
Steel · TRIP1000 temper comparison
TRIP1000-CR and TRIP1000 CR+BH are two conditions of the same steel grade, TRIP1000: CR (cold rolled) versus CR+BH (after paint-bake cycle). The chemistry is identical, so every difference below comes from the condition. TRIP1000 CR+BH is the stronger of the two: yield strength 770 MPa (112 ksi) against 720 MPa (104 ksi) for TRIP1000-CR, about 7% more. In exchange, TRIP1000-CR is the more ductile: elongation 14% versus 12% for TRIP1000 CR+BH.
TRIP1000-CRChoose it when the part is bent, formed or impact-loaded.
TRIP1000 CR+BHChoose it when strength drives the design.
TRIP1000-CR vs TRIP1000 CR+BH: 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.

TRIP1000-CR vs TRIP1000 CR+BH — frequently asked
Is TRIP1000 CR+BH stronger than TRIP1000-CR?
Yes. TRIP1000 CR+BH has a typical yield strength of 770 MPa (112 ksi) against 720 MPa (104 ksi) for TRIP1000-CR — about 7% more. Tensile strength is 1,055 MPa (153 ksi) vs 1,040 MPa (151 ksi).
Which condition does FabDigit quote by default, CR or CR+BH?
CR is the default TRIP1000 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.
When should I choose TRIP1000-CR over TRIP1000 CR+BH?
Pick TRIP1000-CR when the part is bent, formed or impact-loaded. Pick TRIP1000 CR+BH when strength drives the design.
