Precipitaion Hardening Nerjaveèi
Segondè Tanperati alyaj
◆0Cr17Ni7Al se yon asye presipitasyon-redi ak Al te ajoute, yo itilize kòm sous dlo, rondèl, konpozan kalkilatris, elatriye.
◆0Cr15Ni7Mo2Al yo itilize pou resipyan ki gen gwo fòs, pati ak pati estriktirèl ak sèten kondisyon rezistans korozyon.
◆ Pèfòmans 0Cr15Ni5Cu4Nb sanble ak sa 0Cr17Ni4Cu4Nb, men li gen pi bon pèfòmans lateral.
◆0Cr12Mn5Ni4Mo3Al (Gangyan 69111) gen pi bon plastisit pase 0Cr15Ni7Mo2Al.
◆0Cr17Ni4Cu4Nb Presipitasyon redi asye ak Cu te ajoute, lajman ki itilize nan arbr, gwo-fòs pati estriktirèl ki mande rezistans korozyon pou pati turbine vapè.
◆XM-25 se chalè ak tanperati ki wo rezistan, apwopriye pou petwòl, pwodui chimik, ayewospasyal, fòs nikleyè ak lòt endistri yo.
