The magnetic finely dispersed crystal structure in austenitic steels that causes the austenite grains to become smaller and crack resistant.
Welding Tech
The normal crystal structure of low carbon steel at room temperature.
The resistance of a material to repeated or alternating stressing, without failure.
The maximum stress that a material will support indefinitely under variable and repetitive load conditions
The cracking, breaking or other failure of a material as the result of repeated or alternating stressing below the material?s ultimate tensile strength.
