304 Pahu Poʻa Poʻa

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, 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 he 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 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 ka 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 kūpaʻa 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 kiʻi 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:

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