Steel Ductibor 500 vs MS1700

Steel · grade comparison

Steel Ductibor 500 and MS1700 are both steel grades. MS1700 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 420 MPa (60.9 ksi) for Ductibor 500, about 3.5 times as much; tensile strength follows at 1,780 MPa (258 ksi) vs 620 MPa (89.9 ksi). In exchange, Ductibor 500 is the more ductile: elongation 17% versus 4% for MS1700, and MS1700 is harder (520 HV vs 195 HV). Ductibor 500 runs hotter in service (250°C vs 200°C continuous) and Ductibor 500 conducts heat better (45 W/m·K vs 32 W/m·K). On the shop floor, Ductibor 500 machines more easily (good vs poor), Ductibor 500 welds better (very good vs good), and Ductibor 500 sits in a lower cost tier (budget, $) than MS1700 (standard, $$).

Ductibor 500Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

MS1700Choose it when strength drives the design.
