2. I-Saky Steel ipakisha iimpahla zethu ngeendlela ezahlukeneyo ngokusekelwe kwiimveliso. Sipakisha iimveliso zethu ngeendlela ezininzi, ezinje,
I-alloy ye-253Ma ineempawu ezilandelayo:
I-253MA yintsimbi engagqwaliyo ekwaziyo ukumelana nobushushu eyenzelwe usetyenziso olufuna amandla aphezulu okurhubuluza kunye nokumelana okuhle nokugqwala. Ubushushu bayo bokusebenza buyi-850~1100 °C.
Ulwakhiwo lweekhemikhali lwe-253MA lulungelelene, nto leyo eyenza intsimbi ibe neempawu ezifanelekileyo kakhulu kuluhlu lobushushu oluphakathi kwe-850 °C-1100 °C, ukumelana okuphezulu kakhulu kwe-oxidation, kwaye ubushushu besikali bufikelela kwi-1150 °C; ukumelana okuphezulu kakhulu kwe-creep Amandla kunye namandla okuqhekeka kwe-creep; ukumelana okuhle kwi-corrosion ephezulu yobushushu kunye nokumelana ne-brush corrosion kwiindawo ezininzi zegesi; amandla aphezulu okuvelisa kunye namandla okutsalwa kubushushu obuphezulu; ukwakheka okuhle kunye nokudityaniswa kunye nokusebenza ngokwaneleyo koomatshini.
Ukongeza kwizinto ezidibanisa i-chromium kunye ne-nickel, i-253MA stainless steel ikwanayo nenani elincinci le-rare earth metal (i-Rare Earth Metals, i-REM), ephucula kakhulu amandla ayo okulwa ne-antioxidant. I-nitrogen yongezwa ukuphucula iipropati zokuqhekeka nokwenza le ntsimbi ibe yi-austenite epheleleyo. Nangona umxholo we-chromium kunye ne-nickel uphantsi kakhulu, le ntsimbi stainless ineempawu ezininzi zobushushu obuphezulu ezifana ne-alloy steel ephezulu kunye ne-alloy esekelwe kwi-nickel.
Izicelo ze-253Ma:
I-253MA isetyenziswa kakhulu kwizixhobo zokusila, izixhobo ze-blast furnace, ukunyibilika kwentsimbi, izixhobo ze-furnace kunye ne-continuous casting, ii-rolling mills (ii-heating furnace), ii-heat treatment furnaces kunye nezixhobo, izixhobo zezimbiwa kunye nezixhobo zokuvelisa isamente.
