Alloy 28 nicyuma cyinshi cya austenitike kitagira ibyuma bitanga imbaraga zo kurwanya ibitangazamakuru bitandukanye byangirika.Ukurikije ibirimo muri chromium na molybdenum, ibinyobwa bitanga imbaraga zo kurwanya okiside ndetse no kugabanya aside hamwe nu munyu.Kuba umuringa byongera imbaraga zo kurwanya aside sulfurike.Amavuta akoreshwa mu nganda zitunganya imiti na peteroli.Imiyoboro ya aliyumu irakonje ikorwa kugeza murwego rwo hejuru kugirango serivisi zimanuke mu mariba ya gaz yangiza cyane
