316/316L vs 304/304L

ʻO ke ʻano 316/316L/316H he austenitic stainless steel i manaʻo ʻia no ka hoʻohana ʻana i nā noi e koi ai i ka ikaika kiʻekiʻe, ka paʻakikī a me ka hana, a me ka hoʻonui ʻana i ka pale ʻana i ka corrosion.Hoʻohālikelike i ka 304 stainless steel, 316 ka hapa nui o ka molybdenum (Mo 2% -3%) a me ka nickel (Ni 10% a 14%), ʻoi aku ka maikaʻi o ka Molybdenum i ka pale ʻana i ka corrosion holoʻokoʻa, ʻoi aku ka maikaʻi no ka pitting a me ka crevice corrosion i nā kaiapuni chloride.ʻO 316 ka paʻakikī maikaʻi loa a me nā waiwai mīkini i nā mahana sub-zero, kūpono no ka ʻōwili anu, ka pā wili mau a me ke ʻano millplate pā, ka mānoanoa a hiki i 60 iniha.

316L/TP316L Paipu kila kila

ʻO ka papa 316L e pili ana i ka S31603 UNS desination 1.4404, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o TP316 ma muli o ka haʻahaʻa Carbon maʻiʻo.316L kiʻekiʻe kalapona maʻiʻo 0.03% i 316 kiʻekiʻe 0.08%, kiʻekiʻe kalapona e hoʻonui intergranular corrosion.No laila, kūpono ʻo 316L no nā noi kahi e pale ʻia ai ka ua kalapona.Hoʻohana nui ʻia kēia kila kila no ka wili ʻana i nā ʻāpana, ʻo kāna ʻano kalapona kūikawā i hui pū ʻia me ka welding e hōʻoia i ka pale nui loa i ka corrosion maʻamau, pili pono i nā mea hana kaumaha.

Manaʻo ʻia ʻo 316L ʻoi aku ka pale ʻana i ka oxidation ma mua o ka Type 316, ʻoi aku ka maikaʻi ma nā wahi kai mahana.Eia hou, ʻo kāna ʻike kalapona haʻahaʻa e pale iā ia mai ka ua kalapona.Hōʻike ka metala i ke kūʻē ʻana i nā mahana haʻahaʻa loa, a hiki i nā pae cryogenic.Ma ke ʻano o ka pale ʻana i ka wela, hōʻike ʻo 316L i ka ʻoi aku ka maikaʻi o ka creep resistance, fracture stress resistance a me ka ikaika holoʻokoʻa ma mua o nā māka kila kila.

Hiki ke hoʻohana ʻia ka nui o nā hana hana like i kūpono no Type 316 no 316L, me ka weldability a me ka paʻakikī hana anuanu.Eia kekahi, ʻaʻole koi ʻo 316 i ka annealing ma hope o ka lawelawe e hoʻonui i kona kūpaʻa corrosion, akā hiki ke hoʻohana ʻia ka annealing i kekahi mau hihia.

316H/TP316H kila kila

ʻO ka papa 316H e pili ana iā S31609, carbon content 0.04% a i 0.10%, hāʻawi ia i ke kūpaʻa wela kiʻekiʻe ma mua o 316L.

316Ti/TP316Ti

ʻIke ʻia ke kila kila 316Ti ma ke ʻano he pae paʻa o ka ʻano 316 a ʻo ia kekahi o ʻelua 316 stainless steels i ʻōlelo ʻia no nā noi wela kiʻekiʻe.Loaʻa i kēia papa kahi liʻiliʻi (maʻamau 0.5%) o ka titanium.ʻOiai e kaʻana like ana i nā waiwai o nā papa 316 ʻē aʻe, ʻo ka hoʻohui ʻana o ka titanium e pale iā 316Ti mai ka ua i nā wela kiʻekiʻe, ʻoiai me ka hoʻolaha lōʻihi.

Hoʻohui pū ʻia ka Molybdenum i ka haku o 316Ti.E like me nā māka 316 ʻē aʻe, hāʻawi ka molybdenum i ka pale i hoʻonui ʻia i ka corrosion, chloride solution pitting a me ka ikaika ke kau ʻia i nā wahi wela kiʻekiʻe.Eia nō naʻe, hoʻohui pū ʻia kona kūpaʻa wela kiʻekiʻe e kona ʻano titanium, kahi e pale ai ʻo 316Ti i ka ua i kēia mau mahana.Eia kekahi, kū'ē ka metala i nāʻakika e like me ka sulfuric acid, hydrochloric acid, a me ka acid sulfates.
Hoʻohana maʻamau ʻia ʻo 316Ti i nā mea hoʻololi wela, nā mea wili pepa a me nā mea kūkulu hale i nā kaiapuni kai.

TP316LN/316N

316N: Hoʻohui ʻia ka Nitrogen (N) i ka 316 stainless steel e hoʻonui i ka ikaika me ka ʻole o ka hōʻemi ʻana i ka plasticity, i hoʻemi ʻia ka mānoanoa o ka mea.No nā ʻāpana ikaika kiʻekiʻe me ka pale ʻana i ka corrosion.

ʻO 316LN ka 316L me N i hoʻohui ʻia, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o 316N.

TP316 / 316L / 316H / 316Ti Paipu Kūleʻa Kūleʻa

Hoʻohana ʻia ʻo TP316/316L paipu liʻiliʻi no ka hoʻoneʻe ʻana i ka wai a i ʻole ke kinoea i ka mālama wai, ka mālama wai ʻino, ka petrochemical, kemika, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.A ʻo nā noi hoʻolālā e pili ana i nā handrails, nā pou a me nā paipu kākoʻo no ka wai paʻakai a me nā kaiapuni corrosive.Hoʻohālikelike ʻia me TP304 stainless steel, TP316 stainless steel pipe he haʻahaʻa haʻahaʻa haʻahaʻa, no laila ʻaʻole ia e hoʻohana pinepine ʻia e like me ka paipu welded ke ʻole kona kūpaʻa ʻoi aku ka maikaʻi ma mua o ka weldability.
