SS 309S / SS 309H Waea

Ko nga Alloys 309 me te 309S he kowiri tira chromium-nickel austenitic e whakamahia ana mo nga tono pāmahana teitei ake. Na te nui o te chromium me te nickel ihirangi, ko nga Alloys 309 me te 309S he tino atete ki te waikura, he tino atete ki te waikura, me te kaha o te wera i te wa e kaha ana te kaha ki te rūma me te pāmahana teitei. Ko te rereketanga nui i waenga i te 309 me te 309S ko te ihirangi waro, he iti rawa te hanganga waro Alloy 309S e whakaiti ana i te rerenga carbide me te whakapai ake i te weldability.
Nga korero hua
Ko te SS 309S he kowiri tira he kowiri tira austenitic tino whakakotahi i whakamahia mo tona tino aukati i te waikura, te wera-nui, te kaha, me te aukati ngoki. Ko te iti o te nickel i roto i te Kowiri tira 309, ka whakatauritea ki te Kowiri tira 310, ka piki ake tona atete ki te whakaeke hauwai sulfide (H2S) i nga wera nui. He uaua, he ngawari hoki, ka taea te hanga me te miihini. Ko te SS 309S te putanga waro-iti, a, e taunaki ana mo, mo te whakamahi i nga waahi ka raru pea te whakamohiotanga me te waikura o muri mai i te pāmahana teitei i te wa e kati ana. Ko te Kowiri tira 309S e whakamahia ana mo tana parenga waikura teitei me te aukati ki te whakaeke H2S. 309S Kowiri tira ka taea te hanga, te tohu, me te tuhi ngawari. Ko te tikanga whakahiato i roto i te tukanga hei whakanui ake i te ngongo me te whakaiti i te pakeke.
