Abstract:Jekla za turbinske lopatice so zaradi svoje specifične uporabe tehnološko in kakovostno zelo zahtevna ter predstavljajo višji nivo obvladovanja proizvodnjega procesa. Jeklo PT929 (X22CrMoNiV12-1,(W.Nr. 1.4923), je matrenzitnega tipa, obstojno pri povišanih temperaturah do okoli 650°C.Odporno je proti lezenju in vodiku pod tlakom. Uporablja se za različne dele turbin ter dele, ki so odporni proti komprimiranemu vodiku v kemijski industriji. Deli morajo zagotavljati brezhibno delovanje, kar zahteva najvišjo kakovost uporabljenih materialov. Za uporabnost tega jekla je izredno pomembno obnašanje materiala pri konstantnih dolgotrajnih obremenitvah, korozijska obstojnost, majhne dimenzijske spremembe, enakomerna žilavost, enakomerne mehanske lastnosti ter trdota, površina brez napak, kompaktnost materiala ter makro in mikrohomogenost jekla.
Keywords:Jeklo za turbinske lopatice, kakovost, metalurški postopki, tehnologija, specifična uporaba, višji nivo.

Title:PROJECT APPROACH OF BUSINESS AND ORGANIZATIONAL POINTS OF VIEW OF MAKING STEEL PT929 FOR TURBINE BLADES
Abstract:Steels for turbine blades are from their technological and Quality view very demanding because of their specific use, and they represent a higher level of production process management. The PT929 (X22CrMoNiV12-1 steel,(W.Nr.1.4923) is of martensitic type, resistant at increased temperatures up to approx. 650°C.It is creep resistant and resistant to hydrogen under pressure. It is used for different parts of turbines and parts that are resistant to compressed hydrogen in chemical industry. Parts must ensure smooth operation which demands the best quality of materials. For this steel applicability, behaviour of material at constant long-lasting strains, corrosion resistance, small dimensional changes, uniform toughness, uniform mechanical characteristics and hardness, surface free of defects, compactness of materia, and macro and micro homogenity of steel are of significant importance.
Keywords:Steel for turbine blades, quality, metalurgical procedures, technology, specific use, higher level.
