304H Paipu kila kila

HOIKE

304H he austenitic stainless steel, nona ka 18-19% chromium a me 8-11% nickel me ka nui o 0.08% kalapona. ʻO nā paipu kila kila 304H ka mea maʻalahi a hoʻohana nui ʻia i loko o ka ʻohana kila kila. Hōʻike lākou i ke kūpaʻa corrosion maikaʻi loa, ka ikaika nui, ka maʻalahi o ka hana ʻana, a me ka formability maikaʻi loa. No laila, hoʻohana ʻia no nā ʻano like ʻole o ka home a me nā noi ʻoihana. ʻO 304H ke kila kila i hoʻopaʻa ʻia ka maʻiʻo kalapona o 0.04 a 0.10. Hāʻawi kēia i ka ikaika wela kiʻekiʻe, ʻoi aku ma luna o 800o F. Ke hoʻohālikelike ʻia me 304L, 304H mau paipu kila kila ʻoi aku ka nui o ka wā pōkole a me ka ikaika kolo wā lōʻihi. Eia kekahi, ʻoi aku ko lākou kūpaʻa i ka sensitization ma mua o 304L.

304H NA WAIWAI PIPE STEEL

ʻO ka mea i haʻi ʻia ma lalo nei nā hiʻohiʻona koʻikoʻi o nā paipu kila stainless 304H i hāʻawi ʻia e Arch City Steel & Alloy:

Palena wela:

  • He kūpono no nā noi wela kiʻekiʻe, no ka mea, hāʻawi ia i ka ikaika kiʻekiʻe ma nā mahana ma luna o 500 ° C a hiki i 800 ° C

  • Hāʻawi ka papa 304H i ke kūpaʻa oxidation maikaʻi i ka lawelawe intermittent i 870 ° C a ma ka lawelawe mau ʻana i 920 ° C

  • E lilo i sensitized ma ke ana wela o 425-860° C; no laila ʻaʻole ʻōlelo ʻia inā makemake ʻia ke kūpaʻa wai.

Paʻa ʻino:

  • ʻO ke kūpaʻa maikaʻi i ka corrosion i loko o nā kaiapuni oxidizing, a me nā ʻakika organik haʻahaʻa ma muli o ka loaʻa ʻana o ka chromium a me ka nickel.

  • Hana like ma ka hapa nui o nā kaiapuni corrosive

  • Hiki ke hōʻike i ka haʻahaʻa haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka pae kalapona kiʻekiʻe 304.

Weldability:

  • Hoʻopili koke ʻia e ka hapa nui o nā kaʻina hana maʻamau.

  • Pono paha e hoʻopili ma hope o ka wili

  • Kōkua ʻo Annealing i ka hoʻihoʻi ʻana i ke kūpaʻa corrosion i nalowale e ka sensitization.

Ke hana nei:

  • ʻO nā mahana hana manaʻo ʻia o 1652-2102° F
  • Pono e hoʻopili ʻia nā paipu a me nā paipu ma 1900 ° F
  • Pono e kinai ʻia ka wai a i ʻole e hoʻomaloʻo koke
  • ʻO ka papa 304H he ductile a maʻalahi ke ʻano
  • Kōkua ka hana anu i ka hoʻonui ʻana i ka ikaika a me ka paʻakikī o ka papa 304H
  • Hiki i ka hana anu ke hana i ka alloy me ka magnetic

Hiki i ka mīkini:

  • Loaʻa nā hopena maikaʻi loa ma ka māmā māmā, ka lubrication maikaʻi, nā hānai kaumaha, a me nā mea hana ʻoi

  • E pili ana i ka paʻakikī o ka hana a me ka haki ʻana i ka chip i ka wā deformation.

Nā noi o ka papa 304H nā paipu kila kila

ʻO kekahi mau hiʻohiʻona o nā noi i hoʻohana maʻamau ʻia ka papa 304H:

  • Nā hale hoʻoheheʻe ʻaila
  • ʻO nā paila
  • Pipeline
  • Nā mea hoʻololi wela
  • Condensers
  • Puhi mahu
  • Hale hooluolu
  • ʻO nā mea hana uila
  • Hoʻohana ʻia i kekahi manawa i ka mea kanu a me nā mea kanu kemika
