304 Paa Poepoe Hui Kuhiliahi

ʻO 304 ke kila kila kila maʻemaʻe puni e pili ana i ka ʻili maʻemaʻe, i hana ʻia e ka hoʻopau ʻana i ka ʻōwili ʻana, ka ʻili a i ʻole ke kahakaha kiʻi anuanu;hoʻohana pinepine ʻia i nā kemika like ʻole, ka meaʻai, ka textile a me nā mea hana mīkini ʻē aʻe a me kekahi mau mea hoʻonaninani.ʻO ka mea i kapa ʻia ʻo 304 stainless steel ʻeleʻele a i ʻole 304 stainless steel rod (black rod) e pili ana i ke kila poepoe nona ka ʻili ʻeleʻele a ʻeleʻele, ʻōwili wela pololei, hana ʻia, a i hoʻopili ʻia me ka ʻole o ka hoʻoponopono ʻana i ka papa o ka oxide ma ka ʻili.

304: 18-8 stainless steel, ʻo ka papa kuhikuhi GB he 0Cr18Ni9;ʻAmelika hoʻokō maʻamau: 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 304 stainless steel ka mea i hoʻohana nui ʻia i ka chromium-nickel stainless steel, nona ka pale corrosion maikaʻi, ke kūpaʻa wela, ka ikaika haʻahaʻa haʻahaʻa a me nā waiwai mechanical.He kū'ē i ka corrosion i ka lewa.Inā he lewa ʻoihana a he wahi haumia nui paha, pono e hoʻomaʻemaʻe ʻia i ka manawa e pale ai i ka corrosion.[1]

Wahi a ke kaʻina hana, ua māhele ʻia ʻo 304 stainless steel puni i ʻekolu mau ʻano: ʻōwili wela, forging a me ke kaha anu.ʻO ka ʻōlelo kikoʻī o ka pahu wela 304 stainless steel round bar he 5.5-130 mm.Ma waena o lākou: 5.5-25mm liʻiliʻi 304 stainless steel poepoe kila i hāʻawi nui ʻia i nā ʻāpana pololei, hoʻohana pinepine ʻia e like me nā pahu kila, nā kī a me nā ʻāpana mechanical like ʻole;a i ʻole ma ke ʻano poepoe, e like me nā huahana semi-hoʻopau no ka hoʻoponopono hou ʻana.Hoʻohana nui ʻia ʻo 304 stainless steel poepoe ʻoi aku ka nui ma mua o 25 mm no ka hana ʻana i nā ʻāpana mechanical a i ʻole ka hoʻoheheʻe ʻana i nā bilets seamless steel tube.[2]

304 kila kila poepoe kila kaumaha theoretical helu kumu:
