ASTM A333 Papa 6he mea hoʻoheheʻe kalapona i hoʻohana ʻia i ka cryogenic a me nā noi ʻē aʻe e koi ana i ka paʻakikī notched.Hiki iā ia ke hoʻohana ʻia i loko o nā kaiapuni e like me ka haʻahaʻa e like me -45°C (-50°F) a loaʻa iā ia ma nā ʻano seamless a welded.
Hiki ke hoʻohana ʻia ka ASTM A333 i kahikaʻina hana ʻole a welded.
Hoʻokaʻawale ʻia ke kaʻina o ka paipu kila seamless i loko o ka wela wela a me ke anu.A pono e hōʻike ʻia ma luna o ka māka.
ʻO nā paipu kila maʻemaʻe ka koho mua no nā kaiapuni paʻakikī, nā kūlana koʻikoʻi, a inā makemake ʻia nā paipu mānoanoa.
Pono e mālama ʻia ʻo ASTM A333 GR.6 e like me kekahi o kēia mau ala e hoʻokele ai i kāna microstructure:
● Hoʻomaʻamaʻa: E wela i kahi mahana like ʻole ma kahi o 1500 °F [815 °C] ma lalo o ka liʻiliʻi, a laila hoʻolili i ka lewa a i ʻole ke keʻena hoʻoluʻu o ka umu hoʻomalu lewa.
● Tempering ma hope o ka maʻamau: Ma hope o ka hana maʻamau, hiki ke hoʻomaʻamaʻa hou ʻia i ka mahana wela kūpono ma ka manaʻo o ka mea hana.
● No nā kaʻina hana maʻemaʻe, hiki ke hoʻokō ʻia kēia ma ka hoʻomalu ʻana i nā mahana o ka hana wela a me nā hana hoʻopau wela a hiki i nā wela hope loa mai 1550 a 1750 °F [845 a 945 °C] a laila hoʻomālili i ka ea a i kahi lewa- ka umu ahi hoʻomalu ʻia mai kahi mahana mua ma kahi o 1550 °F [845 °C].
● Hiki ke hoʻomaʻamaʻa hou ʻia ka hoʻomaʻamaʻa ʻana ma hope o ka hana wela a me ka hoʻopau ʻana i ka hoʻomaʻamaʻa ʻana i ka wela i ka mahana wela kūpono i ka manaʻo o ka mea hana.
● Hoʻopiʻi a me ka hoʻomaʻamaʻa ʻana: Ma kahi o kekahi o kēia mau lāʻau lapaʻau ma luna, hiki ke mālama ʻia nā paipu lino ʻole o ka Papa 1, 6, a me 10 e ka hoʻomehana ʻana i kahi mahana like ʻole o 1500 °F [815 °C] ma lalo o 1500 °F [815 °C], a ukali ʻia me ke kinai ʻana i ka wai a e hoʻomaʻamaʻa hou i ka mahana hoʻoheheʻe kūpono.
ANo kēlā me kēia hōʻemi ʻana o 0.01% kalapona ma lalo o 0.30 %, e ʻae ʻia ka piʻi ʻana o 0.05% manganese ma luna o 1.06% i ka nui o 1.35% manganese.
CMa ka ʻaelike ma waena o ka mea hana a me ka mea kūʻai mai, hiki ke hoʻonui ʻia ka palena no ka niobium a hiki i 0.05% ma ka nānā ʻana i ka wela a me 0.06% ma ka nānā ʻana i nā huahana.
DʻO nā huaʻōlelo Niobium (Nb) a me Columbium (Cb) he mau inoa ʻē aʻe no ka mea like.

Nā ho'āʻo ʻē aʻe
Loaʻa iā ASTM A333 kahi hoʻāʻo palahalaha, kahi hōʻike hopena, ma kahi o kahi hoʻāʻo tensile.
