Study on carburized steel used in maritime industry: The influences of carburizing temperature
This paper aims to examine the influence of carburizing temperature on carburized mild steel. Carburizing treatment was carried out at carburizing temperatures of 800 and 900 °C with fixed carburizing time of 1 h. The results indicated that carburization treatment could improve the hardness of the samples. However, it was found that the hardness profile of mild steel was almost unchanged after treatment at the carburizing temperature of 800 °C. Carburization treatment carried out at the carburizing temperature of 900 °C could significantly enhance the hardness conditions and also increase the case depth of carburized mild steel. Carburized steel can provide a tough and durable surface to protect against severe degradations, such as marine erosion, wear, and cavitation in maritime applications.
