Dachang maoli 304L kuhiliʻole kila paipu kuai
Hoʻohana ka American Iron and Steel Institute i ʻekolu huahelu e hōʻailona i nā kūlana like ʻole
ʻAno malleable. O ka mea:
① Hōʻike ʻia ke kila kila Austenitic e nā helu o 200 a me 300 series,
②Hōʻike ʻia nā kila kila ferritic a me martensitic e nā helu moʻo 400. No ka laʻana, kekahi o nā mea maʻamau austenitic stainless steels
Hōʻailona 201, 304L, 316 a me 310,
③ Hōʻailona ʻia ke kila stainless Ferritic me 430 a me 446, a ua hōʻailona ʻia ke kila stainless martensitic me 410, 420 a me 440C
Nānā, duplex (austenite ferrite),
④ ʻO ke kila kila, ka ua hoʻopaʻakikī paʻakikī a me ke kila kiʻekiʻe me ka mea hao ma lalo o 50% e hoʻohana pinepine i ka inoa patent a i ʻole ka inoa kālepa.
① Hoʻohana ʻia nā hōʻailona mea kemika honua a me nā hōʻailona aupuni e hōʻike i ka haku mele ʻana, a ua hoʻohana ʻia nā leka ʻAlapia e hōʻike i nā ʻano mea:
No ka laʻana: Kina, Rusia 12CrNi3A
②E hoʻohana i nā helu huahelu paʻa e hōʻike i ka moʻo kila a i ʻole nā helu; No ka laʻana, ʻo ʻAmelika Hui Pū ʻIa, Iapana, 300 series, 400 series a me 200 series.
③ Hoʻokumu ʻia ka helu serial me nā leka Latin a me ke kauoha, e hōʻike wale ana i ke kumu.
Hoʻohana, Pinyin Pākē, kila kapuahi hāmama: P, kila paila: F, kila pepehi ʻia: B, papa a kila: A, T8: te8
GCr15: Poepoe
◆ i hoʻopaʻa ʻia i ke kila a me ke kila puna, e like me 20CrMnTi 60simn, (Ua hōʻike ʻia ka ʻike ma ka ʻumi tausani)
◆ ke kila kila a me ke kila kila (ʻike ʻia ka ʻike C ma nā tausani), e like me ka 1 tausani o 1Cr18Ni9 (ie.
0.1% C), kuhiliʻole C ≤ 0.08%, e like me 0Cr18Ni9, ultra-haʻahaʻa kalapona C ≤ 0.03%, e like me 0cr17ni13mo
Paona no ka mika o 304L paipu kila kila = anawaena o waho - ka manoanoa o ka paia x ka manoanoa o ka paia x0.02491
Element maʻiʻo o 304L kuhiliʻole kila paipu c ≤ 0.03, ni8.00 ~ 12.00, cr18.00 ~ 20.00, Mn < = 2.0, Si < = 1.0, s < = 0.030, P < = 0.035.
304L kuhiliʻole kila paipu 18cr-8ni-haʻahaʻa kalapona e like me Low-C 304 kila, kona corrosion kū'ē like me 304 kila ma ka laulā, akā, kona palena palaoa corrosion kū'ē maikaʻi loa ma hope o ka welding a stress relief; Hiki iā ia ke mālama i ke kūpaʻa corrosion maikaʻi me ka ʻole o ka mālama ʻana i ka wela, a ʻo ka mahana lawelawe - 196 ℃ ~ 800 ℃. Hoʻohana ʻia ia i nā mīkini waho i nā ʻoihana kemika, lanahu a me ka ʻaila me nā koi kiʻekiʻe no ka pale ʻana i ka corrosion palena o ka palaoa, nā ʻāpana wela o nā mea kūkulu hale a me nā ʻāpana me ka paʻakikī i ka mālama wela.
Ke kumu: hoʻohana nui ʻia no ka ʻenekinia wai inu a me ka lawe wai ʻē aʻe me nā koi kiʻekiʻe
Nā hiʻohiʻona nui: ola lōʻihi; Haʻahaʻa haʻahaʻa haʻahaʻa a me ka leakage wai; Maikaʻi ka maikaʻi o ka wai lawe ʻana, ʻaʻohe mea ʻino e hoʻoheheʻe ʻia i loko o ka wai; ʻO ka paia o loko o ka paipu maʻemaʻe a he haʻahaʻa haʻahaʻa i ka lawe ʻana i ka wai; ʻO ka hana koʻikoʻi kiʻekiʻe, ke ola lawelawe a hiki i 100 mau makahiki, ʻaʻohe mālama a me ka uku haʻahaʻa; Hiki iā ia ke pale i ka hoʻoheheʻe ʻana o ka wai kiʻekiʻe ma mua o 30m / S; ʻO ka waiho ʻana o ka paipu i hōʻike ʻia a nani ke ʻano.
Hoʻohana: ka waiū a me ka ʻoihana meaʻai, ka ʻoihana lāʻau lapaʻau, nā ʻoihana me nā koi kūikawā o loko.
Nā hiʻohiʻona kaʻina hana: ka hoʻomaʻamaʻa ʻana i ka weld bead leveling, ka lāʻau hoʻonā paʻa, ka poli electrolytic o loko.
ʻO nā hiʻohiʻona hana: ʻoi aku ka nui o ka roughness o loko Ra ma mua o 0.2, he liʻiliʻi ke koena o ka pā, maʻalahi e hoʻomaʻemaʻe, pale i ka ulu ʻana o ka maʻi bacterial, electrolytic polishing ka hopena passivation, a ʻo ka pā i loko he hana pale maikaʻi.
Nā ʻano hoʻāʻo: hoʻopololei, hoʻopololei lōʻihi, hoʻopololei hoʻohuli, hoʻāʻo hydrostatic a i ʻole ʻike hemahema o kēia manawa, hoʻāʻo waiwai mechanical, hoʻāʻo ʻino ʻili o loko.
