Steel CP1000 vs TRIP690

Steel · grade comparison

Steel CP1000 and TRIP690 are both steel grades. CP1000 is the stronger of the two: yield strength 800 MPa (116 ksi) against 450 MPa (65.3 ksi) for TRIP690, about 78% more; tensile strength follows at 1,050 MPa (152 ksi) vs 720 MPa (104 ksi). In exchange, TRIP690 is the more ductile: elongation 26% versus 8% for CP1000, and CP1000 is harder (315 HB vs 210 HB). TRIP690 conducts heat better (45 W/m·K vs 32 W/m·K). On the shop floor, TRIP690 sits in a lower cost tier (budget, $) than CP1000 (standard, $$).

CP1000Choose it when strength drives the design.

TRIP690Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
