“…One of these boron steels is 30MnB5 (1.5531) steel, which is frequently used in the automotive industry to manufacture the front axles of industrial vehicles [14,15]. It is a steel alloyed with chromium and molybdenum and acquires its final mechanical properties after being subjected to a quenching and tempering treatment.…”

“…It is a steel alloyed with chromium and molybdenum and acquires its final mechanical properties after being subjected to a quenching and tempering treatment. The starting microstructure of this steel is, fundamentally, pearlitic, with the presence of some particles of ferrite and cementite [14][15][16], obtaining a microstructure formed mainly by tempered martensite [15,16] after heat treatment. One of the advantages of 30MnB5 steels is that quenching and tempering makes the steel stronger and harder, thus increasing the durability of the final components that usually have a useful life that is double or triple that of items made from 65 G grade steels [17].…”

In this study, a comparative analysis of the fatigue behavior of four types of steels, three of quenching and tempering (30MnB5 subjected to two different heat treatments and 41CrS4) and one microalloyed (30MnVS6), was carried out. The objective of the study is to determine if it is feasible to replace the quenching and tempering steel traditionally used in the manufacture of commercial vehicle axles (30MnB5) with alternative ones with the same composition but with modifications in their microstructure that improve their mechanical properties; a quenched and tempered chromium steel (41CrS4) and one that is microalloyed (30MnVS6). For this, rotary-bending fatigue tests have been carried out on the four types of steels with different stress levels. The fatigue resistance of quenched and tempered steels and microalloyed steel was evaluated using the fit of Basquin’s experimental data. Where possible, the fatigue limit was determined using the maximum likelihood method. It was concluded that, in general, the fatigue resistance of chromium-alloyed steel is higher than that of the reference steel, while the rest have lower fatigue resistance. On the other hand, it was determined that the fatigue limit of microalloyed steel is higher than the reference one and that of the reference steel is higher than that of the other two steels.

30MnB5 çeliği tarımsal mekanizasyon endüstrisinde sertlik, mukavemet, darbe ve aşınma direnci istenen uygulamalarda kullanılabilen bir çelik türüdür. Günümüz endüstrisinde ekonomik faktörlerin giderek önem kazanması tarımsal mekanizasyonda daha uzun ömürlü tarım makinelerinin üretilmesini gerektirmektedir. Bu nedenle tarımsal mekanizasyonda kullanılan söz konusu çeliğin kullanımı ve kaynaklı birleştirilmesi önem arz etmektedir. Bu çalışmada, 30MnB5 çelikleri MAG kaynak yöntemiyle birleştirilmiş ve üç farklı (havada, suda ve yağda) soğutma rejiminde soğutulmuştur. Soğutma rejimine bağlı olarak kaynaklı 30MnB5 çeliğinin mekanik ve makro/mikroyapı özelliklerindeki değişimi tespit etmek için tahribatsız (görsel muayene, sıvı penetrant testi), tahribatlı (darbe, eğme, sertlik testleri) ve metalografik testler yapılmıştır. Görsel muayene ve sıvı penetrant testi sonucunda kaynak dikişlerinde herhangi bir makro ve mikro hataya rastlanmamıştır. Kaynaklı numunelerde soğutma rejimine bağlı olarak mekanik ve mikroyapı özelliklerindeki değişimler gözlemlenmiştir.
