Steel TRIP Steel-HR vs TRIP Steel TRIP980

Steel · TRIP Steel temper comparison

TRIP Steel-HR and TRIP Steel TRIP980 are two conditions of the same steel grade, TRIP Steel: HR (hot rolled) versus TRIP980. The chemistry is identical, so every difference below comes from the condition. TRIP Steel TRIP980 is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 460 MPa (66.7 ksi) for TRIP Steel-HR, about 39% more; tensile strength follows at 1,020 MPa (148 ksi) vs 750 MPa (109 ksi). In exchange, TRIP Steel-HR is the more ductile: elongation 24% versus 17% for TRIP Steel TRIP980, and TRIP Steel TRIP980 is harder (299 HB vs 223 HB). On the shop floor, TRIP Steel-HR machines more easily (fair vs poor).

TRIP Steel-HRChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

TRIP Steel TRIP980Choose it when strength drives the design.

TRIP Steel-HR vs TRIP Steel TRIP980 — frequently asked

Is TRIP Steel TRIP980 stronger than TRIP Steel-HR?

Yes. TRIP Steel TRIP980 has a typical yield strength of 640 MPa (92.8 ksi) against 460 MPa (66.7 ksi) for TRIP Steel-HR — about 39% more. Tensile strength is 1,020 MPa (148 ksi) vs 750 MPa (109 ksi).

Which condition does FabDigit quote by default, HR or TRIP980?

CR is the default TRIP Steel condition in the FabDigit quote flow (neither HR nor TRIP980). 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-HR or TRIP Steel TRIP980?

TRIP Steel-HR. Its machinability rates fair (38/100) against poor (28/100) for TRIP Steel TRIP980; for welding the order is TRIP Steel-HR first (good, 58/100) then TRIP Steel TRIP980 (fair, 52/100).
