304 Koʻokoʻo kila kila poepoe

ʻO ke kila kila kila poepoe 304 e pili ana i ka ʻili laumania, kahi i hana ʻia ma ka hoʻopau ʻana i ka ʻōwili, ka ʻili ʻana a i ʻole ke kaha kiʻi anu ʻana; hoʻohana pinepine ʻia ia i nā kemika like ʻole, nā meaʻai, nā lole a me nā lako mīkini ʻē aʻe a me kekahi mau kumu hoʻonaninani. ʻO ka mea i kapa ʻia ʻo 304 kila kila poepoe ʻeleʻele a i ʻole 304 koʻokoʻo kila kila (koʻokoʻo ʻeleʻele) e pili ana i ke kila poepoe nona ka ʻili he ʻeleʻele a ʻāwili, ʻōwili pololei ʻia i ka wela, hoʻoheheʻe ʻia, a i ʻole annealed me ka ʻole o ka hana ʻana i ka papa oxide ma ka ʻili.

304: 18-8 kila kila, ʻo ka papa kuhikuhi GB he 0Cr18Ni9; ʻO ke kūlana hoʻokō kūlana ʻAmelika: ASTM A276.

GB: C≤0.07; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni: 8.0-11.0; Cr: 17.0-19.0

ASTM: C≤0.08; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni:8.0-11.0; Kr:18.0-20.0

ʻO ke kila kila 304 ka kila kila chromium-nickel i hoʻohana nui ʻia, nona ke kūpaʻa maikaʻi i ka pala, ke kūpaʻa wela, ka ikaika haʻahaʻa a me nā waiwai mechanical. He kūpaʻa ia i ka pala i ka lewa. Inā he lewa ʻoihana a i ʻole kahi i haumia nui ʻia, pono e hoʻomaʻemaʻe ʻia i ka manawa kūpono e pale aku i ka pala. [1]

Wahi a ke kaʻina hana, ua māhele ʻia ke kila poepoe kila kila 304 i ʻekolu ʻano: ka ʻōwili wela, ka forging a me ke kahakiʻi anu. ʻO ke kikoʻī o ka ʻōwili wela kila kila 304 he 5.5-130 mm. I waena o lākou: 5.5-25mm liʻiliʻi 304 kila poepoe kila kila i hoʻolako nui ʻia i nā ʻāpana pololei, hoʻohana pinepine ʻia e like me nā kila kila, nā bolts a me nā ʻāpana mechanical like ʻole; a i ʻole pololei i ke kūlana poepoe, e like me nā huahana semi-hoʻopau no ka hana hou ʻana ma hope. Hoʻohana nui ʻia ke kila poepoe kila kila 304 ʻoi aku ka nui ma mua o 25 mm e hana i nā ʻāpana mechanical a i ʻole e perforate i nā billets paipu kila seamless. [2]

ʻO ke ʻano helu kumumanaʻo o ke kaumaha kila poepoe 304 kila kila:

Kaumaha no ka mika (kg) = anawaena * anawaena * 0.00623
