| Description
| - Na základě zkoušek korozního praskání v roztocích chloridů se jeví slitina 800 (ocel NiCrTiAl33-21) ve stavu po rozpouštěcím žíhání v porovnání s jinými korozivzdornými ocelemi jako velmi odolná proti koroznímu praskání se zřetelem na obsah niklu. Snížení obsahu uhlíku ovlivňuje její odolnost v tomto stavu jen nevýrazně. Zcitlivění tohoto materiálu v kritické oblasti za nízkých teplot vede ke zvýšení jeho náchylnosti k mezikrystalovému napadení a koroznímu praskání přecházejícímu z vnitrokrystalového na mezikrystalové. Tyto poznatky vedly ke sledování změn na hranicích zrn a zajištění odolnosti proti mezikrystalovému napadení. Dlouhodobé vystavení nízkým teplotám (např. 450oC - vzorek po 30 000h z průmyslové pece) vede k výraznému zcitlivění slitiny 800. Elektrochemickou potenciokinetickou reaktivační metodou (EPR-testem) byla jednoznačně prokázána citlivost tohoto vzorku a odolnost u vzorku pracujícího při 650oC/30 000h pouze slabě náchylného nebo necitlivého. Ochuzení hranic o chrom za nízké teploty (cs)
- On the basis of stress corrosion testing in the chloride solutions seems the 800 alloy (NiCrTiAl33-21) after solution annealing, in the comparison with other stainless steels, as very resistant against stress corrosion cracking adequately to the content of nickel. Reducing of the content of carbon affects in this state only inexpressively its resistance. Sensitization of this material in the low critical zone of temperatures leads to increasing its sensibility to intergranular attack and stress corrosion cracking varies from transgranular to intergranular mode. These findings point out a requirement to study the changes on grain boundaries and the assurance of resistance to intergranular attack. The long-termed exposure at low temperature (e.i. 450oC-probe after 30 000h from industrial oven) leads to considerable sensibility of 800 alloy. With electrochemical potentiokinetic reactivation method (EPR-test) was reliably determine the susceptibility of this probe and the resistance on the probe working a
