Abstract Cromax C35E is a hard-chrome plated product based on medium-carbon steel. Compared with the traditional C45E-base, C35E offers improved weldability. However, by means of thermomechanical processing, the mechanical properties of the C35E used for Cromax products are rendered equivalent to those attainable in C45E. This datasheet provides information on composition and tensile properties. It also includes information on corrosion resistance as well as machining and joining. Filing Code: SA-745.

Ni-B/Ni-B-B4C composite coatings on the substrate of medium-carbon steel (45#) were successfully fabricated by electroless plating in a low temperature bath. The corrosion resistance of Ni-B coating were examined by using electrochemical workstation. The results indicated that there are no pores and cracks and other defects at the interface between the substrate and composite coating. It was found that the corrosion resistance of Ni-B coating increased and then decreased with the addition of NaBH4 increasing, and the best addition in plating bath was about 0.9 g/L. While the corrosion resistance of Ni-B coating heat-treated at 400°C with NaBH4 addition 0.9 g/L was the worst.

Diffusion Boriding

Abstract The paper presents the study results of macro- and microstructure, microhardness and corrosion resistance of C45 medium carbon steel and CT90 high carbon steel after diffusion boriding and laser modification by diode laser. It was found that the increase of carbon content reduced the thickness of boronized layer and caused change in their morphology. Diffusion boronized layers were composed of FeB and Fe2B iron borides. As a result of laser surface modification of these layers, the microstructure composed of three areas: remelted zone, heat affected zone (HAZ) and the substrate was obtained. Microhardness of laser remelting boronized layer in comparison with diffusion boronized layer was lower. The presence of HAZ was advantageous, because mild microhardness gradient between the layer and the substrate was assured. The specimens with laser boronized layers were characterized by better corrosion resistance than specimens without modified layer.

Circumferential Notch

Combined effects of notches and microstructure on the structural performance of medium carbon steel breakaway couplings were discussed. Property troughs commonly associated with tempered martensite embrittlement were characterized as a function of temper for AISI 4130 and 4140 steel couplings. It was observed that a circumferential notch could change the fracture mode from ductile to brittle with no change in tempering condition. Notch-strengthening, a second significant effect, was also observed in similar couplings with an average strength increase of thirty percent. A critical assessment was made of the AASHTO specifications on breakaway couplings used for highway structures and of their interpretation by individual states.
