Comparison of fatigue characteristics of 38ХН3МФА and 40ХН high-tensile-strength steels based on test results

Object and purpose of research. The object of work is steel “38ХН3МФА”, planned for use in the propeller shafts manufacture of the lead-ship (project 10510), and less strong steel “40XH”, used in the propeller shafts manufacture for icebreakers of lower ice categories and lower power.

The object of work is steel “38ХН3МФА”, planned for use in the propeller shafts manufacture of the lead-ship (project 10510), and less strong steel “40XH”, used in the propeller shafts manufacture for icebreakers of lower ice categories and lower power. The purpose of the study is to compare the fatigue strength of these steel grades. Materials and methods. Investigations of the fatigue strength characteristics of steels were carried out by cyclic tests of flat notched specimens in air and cylindrical specimens in fresh water. Main results. It is shown that lowest fatigue strength results correspond to external cyclic loading of specimens with stress concentrator (notch). But even in these conditions, fatigue strength of 38ХН3МФА steel is better than that of 40XH steel. As for the tests of smooth samples in fresh water, 38ХН3МФА steel also has a clear advantage over 40XH steel. Conclusion. The studies have shown that fatigue strength characteristics of 38ХН3МФА steel in the air and in corrosive environment exceed those of 40XH steel. Environmental sensitivity and stress concentration of 38ХН3МФА steel turned out to be higher than for 40KH steel.

abstract	Object and purpose of research. The object of work is steel “38ХН3МФА”, planned for use in the propeller shafts manufacture of the lead-ship (project 10510), and less strong steel “40XH”, used in the propeller shafts manufacture for icebreakers of lower ice categories and lower power. The purpose of the study is to compare the fatigue strength of these steel grades. Materials and methods. Investigations of the fatigue strength characteristics of steels were carried out by cyclic tests of flat notched specimens in air and cylindrical specimens in fresh water. Main results. It is shown that lowest fatigue strength results correspond to external cyclic loading of specimens with stress concentrator (notch). But even in these conditions, fatigue strength of 38ХН3МФА steel is better than that of 40XH steel. As for the tests of smooth samples in fresh water, 38ХН3МФА steel also has a clear advantage over 40XH steel. Conclusion. The studies have shown that fatigue strength characteristics of 38ХН3МФА steel in the air and in corrosive environment exceed those of 40XH steel. Environmental sensitivity and stress concentration of 38ХН3МФА steel turned out to be higher than for 40KH steel.
