Fatigue lifetimes of 1.4306 and 1.4307 stainless steels subjected to ultrasonic loading

Original language description

The contribution brings results of high-frequency fatigue tests of the 1.4306 and 1.4307 steels. The S304L austenitic stainless steels are the most versatile and widely used stainless steels. They are used in food processing, chemical industry, petrochemicals, but also in mechanical and civil engineering. The 1.4306 steel is more highly alloyed and more corrosion resistant than 1.4307. A new trend in bridge structures is the use of stainless steels for their corrosion resistance and mechanical properties. The bridge structures are loaded cyclically and are designed for decades of operation. Thus, long-term fatigue properties are an important issue. The results of experimental studies serve as inputs for a reliable assessment of the service life of cyclically loaded structures. Measurements of both steel types were performed on ultrasonic fatigue testing systems. Cyclic loading was performed in fully reversed push-pull mode with the stress ratio R = - 1. Experimental results plotted in the S-N curves are shown. From the results, it can be concluded that 1.4306 steel shows a slightly higher fatigue resistance than 1.4307 steel. The failure in the gigacycle region (around 10^8 and 10^9 cycles) only occurs in the case of 1.4306 steel. Fracture surfaces were analyzed and only surface crack initiation was observed.
