Steel TRIP600-CR vs TRIP600-HR

Steel · TRIP600 temper comparison

TRIP600-CR and TRIP600-HR are two conditions of the same steel grade, TRIP600: CR (cold rolled) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. TRIP600-HR is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 390 MPa (56.6 ksi) for TRIP600-CR, about 8% more. In exchange, TRIP600-CR is the more ductile: elongation 29% versus 25% for TRIP600-HR, and TRIP600-HR is harder (15 HRC vs 14 HRC).

TRIP600-CRChoose it when the part is bent, formed or impact-loaded.

TRIP600-HRChoose it when strength drives the design.

TRIP600-CR vs TRIP600-HR — frequently asked

Is TRIP600-HR stronger than TRIP600-CR?

Yes. TRIP600-HR has a typical yield strength of 420 MPa (60.9 ksi) against 390 MPa (56.6 ksi) for TRIP600-CR — about 8% more. Tensile strength is 640 MPa (92.8 ksi) vs 650 MPa (94.3 ksi).

Which condition does FabDigit quote by default, CR or HR?

CR is the default TRIP600 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 TRIP600-CR over TRIP600-HR?

Pick TRIP600-CR when the part is bent, formed or impact-loaded. Pick TRIP600-HR when strength drives the design.
