Fatigue strength of EH36 steel welded joints and base

Fatigue tests are performed on base-metal and T-joint fillet-welded specimens of EH36 high strength steel at room temperature and -40.A S-N curve and a P-S-N curve with a survival probability of 97.5% are fitted to the test results.It is found that the scatter in fatigue life at low temperature is smaller than that at room temperature. Fatigue strength scatter characteristics of JIS SUS630 The scatter behavior of fatigue strength for 17-4 PH stainless steel (JIS SUS630,equivalent to ASTM-A563 Grade 630),which exhibited a duplex SN curve,was investigated.It was found that the
