AISI 430 Kuhiwi Kuhiliʻole hoʻolei ʻana i nā Blades

ʻO ka hoʻolei kālāke kaʻina hana, me kona maikaʻi huahana i hoʻopau ʻia a me nā mana hana hana paʻakikī, kūpono loa i nā ʻano oAISI 430 kila kila, no laila ʻaʻole i hoʻokō wale nā ​​​​lau nozzle i nā koi kiʻekiʻe, akā hiki i nā kiʻekiʻe hou i ka paʻakikī o ke kūkulu ʻana a me ka hoʻohana ʻana i nā mea.

ʻO ka haku melemele a me ka microstructure

ʻO ka hui kemika o AISI 430 stainless steel ka mea nui o Cr, me kahi ʻike ma waena o 11.5% a me 14.5%. Hāʻawi kēia ʻike chromium kiʻekiʻe i ka mea antioxidant maikaʻi loa a me ka pale corrosion. I ka manawa like, loaʻa iā ia ka nui o Mo, maʻamau ma waena o 0.50% a me 1.50%, kahi e hoʻonui ai i kona kūʻē ʻana i kekahi mau media corrosive kikoʻī. ʻO ka maʻiʻo o Si, P a me S ua mālama ponoʻia e hōʻoia i ka maʻemaʻe o ka mea a me ka paʻa o kona mau mea mechanical. I ka ʻōlelo o ka microstructure, hōʻike ʻo AISI 430 i kahi morphology grain ferrite, ʻaʻole ia e hoʻonui wale i ka ikaika o ka mea, akā hoʻomaikaʻi pū i kona paʻakikī a me ka hana ʻana.

Mechanical waiwai a me ka wela wela

ʻO ka ikaika tensile o AISI 430 ke kila kila ma waena o 485 MPa a me 620 MPa, a ʻo ka ikaika hoʻohua ma kahi o 205 MPa. He paʻakikī maikaʻi, ductility a me ka paʻakikī hopena. Ma o ka ponolapaʻau wela, e like me ka annealing a i ʻole ka normalizing, hiki ke hoʻonui hou ʻia kona mau mea mechanical, e like me ka hoʻonui ʻana i ka ikaika a me ka hoʻohaʻahaʻa ʻana i ka brittleness, ʻoiai e mālama ana i ke kūpaʻa corrosion maikaʻi loa. ʻOi aku ma nā wahi wela kiʻekiʻe, hiki i ka AISI 430 stainless steel ke mālama i ka paʻa maikaʻi a ʻaʻole hiki ke hoʻololi i ka oxidation a i ʻole ka thermal embrittlement.
