The ọkwa 310 ejikọtawo elu okpomọkụ na nrụgide Njirimara na ezi weldability na ductility.Emebere ya site na iji ọrụ okpomọkụ kacha.Ọ na-eguzogide oxidation nke ukwuu na ma ọrụ na-akwụsịtụ oge yana ọrụ na-aga n'ihu.Ọ nwere ike iguzogide okpomọkụ nke ihe dịka 1150 degrees C na obere gas sọlfọ.N'ime ọrụ ndị na-adịte aka, okpomọkụ nwere ike ịbụ 1040 degrees C.
Enwere ike iji ọkwa 310S nke a makwaara dị ka UNS S31008 mgbe ngwa ụlọ ọrụ na-achọ mmiri corrodents na oke okpomọkụ.Ike dị elu ebelatala ọdịnaya carbon.
Ọ nwekwara ike siri ike dị ka akara ule ndị ọzọ yana nguzogide dị mma na okpomọkụ cryogenic.Ọkwa 310 nwere ọdịnaya carbon 0.03%.Ọ kọwapụtala nguzogide corrosion na gburugburu ebe dị ka mmepụta urea.
