Hoʻolei ʻia nā mea hoʻoheheʻe ʻana i ke kila kila

Ma RMC Foundry, ka hapa nui o kanā hoʻoheheʻe kila kuhiliʻolehana ʻia e ka wax nalowalekaʻina hoʻolei kālāno ka pololei loa. ʻO ke kila kila (SS no ka pōkole) ʻo ia ka pōkole o ke kila kila a me ka waika. Ua kapa ʻia ʻo ia he kila kila ʻaʻole hiki ke hoʻopaʻa ʻia i nā media corrosive nāwaliwali e like me ka ea, ka mahu, a me ka wai. Ua kapa ʻia ke kila corrosion i ke kila ʻakika. Hiki iā mākou ke ninini i nā ʻāpana ʻāpana he nui e like me Ferritic Stainless Steel, Martensitic Stainless Steel, Austenitic Stainless Steel, Precipitation Hardening Stainless Steel a meDuplex Stainless Steel(DSS). ʻO ke kila kila Austenitic, ka mea e pili ana i ka hui o ke kila kila me kahi ʻano austenitic ma ka lumi wela, ʻo ia ka mea i hoʻohana nui ʻia no ka hoʻoheheʻe kālā. ʻO Austenitic stainless steel kekahi o nā papa ʻelima o ke kila kila ma ke ʻano crystalline (me ka ferritic, martensitic, duplex a me ka ua paʻakikī). I kekahi mau wahi, ua kapa ʻia ka austentite stainless steel i ka 300 series stainless steel. Ke loaʻa i ke kila ma kahi o 18% Cr, 8% -25% Ni, a ma kahi o 0.1% C, he hale austenite paʻa. ʻO Austenitic chromium-nickel stainless steel ka mea kaulana 18Cr-8Ni kila a me ke kila Cr-Ni kiʻekiʻe i hoʻomohala ʻia ma ka hoʻohui ʻana i ka ʻike Cr a me Ni a me ka hoʻohui ʻana iā Mo, Cu, Si, Nb, Ti a me nā mea ʻē aʻe ma kēia kumu. Austenitic kuhiliʻole kila he non-magnetic a he kiʻekiʻe toughness a me ka plasticity, akā, kona ikaika haʻahaʻa, a me ka mea hiki ole ke hooikaika ia ma ka māhele hoʻololi. Hiki ke hooikaika wale ia e ka hana anu. Inā hoʻohui ʻia nā mea e like me S, Ca, Se, Te, loaʻa iā ia nā waiwai maikaʻi o ka machinability.
