Paipu kila kila humuhumu ʻole 316l

ʻO nā paipu kila wili ʻole he mau paipu kila ia e kū i nā mea ʻino palupalu e like me ka ea, ka mahu, a me ka wai, a me nā mea ʻino kemika e like me nā waikawa, alkalis, a me nā paʻakai. Ua ʻike ʻia hoʻi he paipu kila kūpaʻa waikawa kila.

ʻO ke kūpaʻa ʻana o ka palaho o nā paipu wili ʻole kila kila e pili ana i nā mea hoʻohuihui i loko o ke kila. ʻO Chromium ke kumu no ke kūpaʻa ʻana o ka palaho o ke kila kila. Ke hiki aku ka nui o ka chromium i loko o ke kila ma kahi o 12%, launa pū ka chromium me ka oxygen i loko o ka mea ʻino e hana i kahi kiʻiʻoniʻoni oxide lahilahi loa (kiʻiʻoniʻoni self-passivation) ma luna o ka ʻili o ke kila. , Hiki ke pale aku i ka palaho hou ʻana o ka matrix kila. Ma waho aʻe o ka chromium, ʻo nā mea hoʻohuihui i hoʻohana pinepine ʻia no nā paipu wili ʻole kila kila e komo pū me ka nickel, molybdenum, titanium, niobium, keleawe, nitrogen, a me nā mea ʻē aʻe, e hoʻokō i nā koi o nā hoʻohana like ʻole no ke ʻano a me ka hana o ke kila kila.

ʻO ka paipu kila kila ʻole he kila poepoe lōʻihi hakahaka, hoʻohana nui ʻia i ka ʻaila, kemika, lāʻau lapaʻau, meaʻai, ʻoihana māmā, nā mea hana mīkini a me nā paipu ʻoihana ʻē aʻe a me nā ʻāpana kūkulu mīkini. Eia kekahi, i ka wā e like ai ka ikaika o ke kūlou a me ka torsion, ʻoi aku ka māmā o ke kaumaha, no laila hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mīkini a me nā ʻōnaehana ʻenekinia. Hoʻohana pinepine ʻia hoʻi e hana i nā mea kaua maʻamau, nā barela, nā pūpū, a pēlā aku.
