The stress-wave emission (SWE) in several alloy steels which are frequently used as structural materials si observed during tensile testing. As to steels SB42, A387-C, and A515, a great amount of SWE is detected in the stage of initial yielding of every specimen annealed even at comparative low temperatures. This experimental result suggests the usefulness of the SWE technique for nondestructive testing and safety monitoring of structures. On the other hand, in case of stainless steel SUS 27 that is solution-treated, little SWE is recorded compared with the alloys above mentioned.
