Heat treatment/condition: As-hardened condition.
Note: During solidification of an ingot, the steel production process involves unavoidable alloying element segregations. On a grain size scale this is known as microsegregations or crystal segregations, on the ingot scale they are called macrosegregations or ingot segregations. These inhomogeneities exert a negative effect on the transverse toughness properties, above all. The positive effects of the production technology employed for 1.2344 steel on microsegregation are shown most effectively using the electron beam microprobe method to measure the difference in concentration of alloying elements.
