Uhlolojikelele
Isicelo
Isetshenziswa kakhulu ukwenza ipayipi lensimbi ye-alloy esezingeni eliphakeme yepayipi le-boiler elicindezela kakhulu, ipayipi lokushintshanisa ukushisa kanye nepayipi lokushisa eliphakeme.
Ibanga Eliyinhloko
Ibanga eliphezulu lensimbi ye-Alloy: T2, T12, T11, T22, T91, T92 njll.
