Ụdị mpempe akwụkwọ igwe anaghị agba nchara atọ
Dị ka crystalline Ọdịdị nke perforated igwe anaghị agba nchara, ọ nwere ike nkewa n'ime atọ ụdị: Austenitic, Ferritic na Martensitic.
Austenitic ígwè, nke nwere ọdịnaya dị elu nke chromium na nickel, bụ ígwè na-eguzogide ọgwụ na-enweghị atụ nke na-enye ihe eji arụ ọrụ na-enweghị atụ, si otú a na-aghọ ụdị alloy a na-ahụkarị, na-aza ihe ruru 70% nke mmepụta igwe anaghị agba nchara. Ọ bụ ihe na-abụghị magnetik, enweghị ike ịgwọ ya mana enwere ike ịgbanye ya nke ọma, guzobe ya, ka ọ na-eme ka obi sie ya ike site na ịrụ ọrụ oyi.
l Ụdị 304, nke ígwè mejupụtara, 18 - 20% chromium na 8 - 10% nickel; bụ ọkwa austenitic kachasị adịkarị. Ọ bụ weldable, machinable maka ngwa dị iche iche, ma e wezụga na gburugburu mmiri nnu.
l Ụdị 316 bụ ígwè, 16 - 18% chromium na 11 - 14% nickel. E jiri ya tụnyere ụdị 304, ọ nwere nguzogide corrosion ka mma ma na-enye ike ya na weldability na machinability yiri ya.
l Ferritic ígwè bụ ogologo chromium ígwè na-enweghị nickel. A bịa na nguzogide corrosion, ferritic dị mma karịa akara ule martensitic mana ọ dị ala na igwe anaghị agba nchara austenitic. Ọ bụ magnetik na oxidation eguzogide, Ọzọkwa; ọ na-arụ ọrụ zuru oke na gburugburu mmiri. Ma enweghi ike imesi ya ike ma ọ bụ ike site na ọgwụgwọ okpomọkụ.
