Age hardening non-heat treated bainitic steel

An age-hardenable steel having a composition consisting of: C: 0.05 to 0.20%, Si: 0.01 to 0.50%, Mn: 1.5 to 2.5%, S: 0.005 to 0.08%, Cr: more than 0.50% and not more than 1.6%, Al: 0.005 to 0.05%, V: 0.25 to 0.50%, Mo: 0 to 1.0%, Cu: 0 to 0.3%, Ni: 0 to 0.3%, Ca: 0 to 0.005%, and Bi: 0 to 0.4%, the balance being Fe and impurities. Within the impurities, P&#x2264;0.03%, Ti&#x3c;0.005%, and N&#x3c;0.0080%, and [C+0.3Mn+0.25Cr+0.6Mo&#x2265;0.68], [C+0.1Si+0.2Mn+0.15Cr+0.35V+0.2Mo&#x2264;1.05], and [&#x2212;4.5C+Mn+Cr&#x2212;3.5V&#x2212;0.8Mo&#x2265;0.12]. The steel has hardness before aging of not more than 310 HV. After aging, the fatigue strength is not less than 480 MPa and absorbed energy at 20&#xb0; C. is not less than 12 J.

Hot-forged section material and common rail

In a fuel injector, a body has formed therein a spray hole and a fuel supply passage. Fuel supplied to the fuel supply passage is delivered to the spray hole. A fuel pressure sensor produces a signal indicative of a pressure of the fuel. First terminals are attached to the fuel pressure sensor and include a terminal for outputting the signal. The fuel pressure sensor is threadedly installed in the body while the first terminals are rotated. A connector includes a housing attached to the body, and second terminals supported by the housing for external electric connection of the fuel pressure sensor. Wires are operative to establish electrical connection between the first terminals and the second terminals. A wire holder is configured to hold each of the plurality of wires at least partly around the fuel pressure sensor.
