Steel TRIP Steel-HR vs TRIP Steel TRIP590

Steel · TRIP Steel temper comparison

TRIP Steel-HR and TRIP Steel TRIP590 are two conditions of the same steel grade, TRIP Steel: HR (hot rolled) versus TRIP590. The chemistry is identical, so every difference below comes from the condition. TRIP Steel-HR is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 400 MPa (58 ksi) for TRIP Steel TRIP590, about 15% more; tensile strength follows at 750 MPa (109 ksi) vs 630 MPa (91.4 ksi). In exchange, TRIP Steel TRIP590 is the more ductile: elongation 30% versus 24% for TRIP Steel-HR, and TRIP Steel-HR is harder (223 HB vs 190 HB). On the shop floor, TRIP Steel TRIP590 welds better (68 vs 58 out of 100).
