He maha nga tangata he ngawari ki te whakapoauau i te putorino kowiri tira 316 me te putorino kowiri tira 316L, me te whakaaro he rite tonu te ahua o te putorino maitai, engari kaore.
Ko nga rereke rereke i waenga i te 316 me te 316L kowiri tira e whai ake nei:
1. Hanga matū
Ko te ihirangi waro o te 316L kowiri tira he iti ake i tera o te 316 kowiri tira.Ka taea te kii ko te "316L" he waro iti-iti 316 he kowiri tira.316L kowiri tira he nui ake te ihirangi molybdenum i te 316.
2. Te aukati waikura
316L kowiri tira he pai ake te aukati waikura.
3. Te kaha
316 he kaha ake nga taonga miihini.Ko te kaha tensile o 316 paipa kowiri tira he teitei ake i tera o te 316L paipa kowiri tira.Ko te kaha kaha o te 316 kowiri tira e hiahiatia ana kia nui ake i te 520MPa, engari ko te 316L kowiri tira e hiahiatia ana kia nui ake i te 480MPa.Ko te mea ko te waro (C) he huānga hanga austenitic kaha, ka taea te whakapai ake i te kaha o te maitai.
4. Te ātete teitei o te pāmahana
316L kowiri tira ka taea te whakamahi tonu i te pāmahana teitei, ko te 316 kaore e taea.I roto i te awhe o 800 ~ 1575 nekehanga, he pai ake kia kaua e mahi tonu i runga i te 316 kowiri tira.He pai ake te carbide precipitation resistance o 316L kowiri tira i te 316 kowiri tira, a ka taea te whakamahi tonu i roto i te awhe o 800 ~ 1575 nekehanga.
5. Wehehanga
316 kowiri tira he pai weldability, e taea te paiherea e tikanga fehokotaki'anga paerewa whānui.Ko te waahanga whakapiri o te 316 he kowiri tira e hiahia ana ki te whakahiato i muri mai hei whakapai ake i te aukati i te waikura.Heoi, ki te whakamahia he kowiri tira 316L, karekau e hiahiatia te whakahiato i muri mai.
