440 pōpō kila kila kiʻekiʻe ka pololei

Nīnau: Pehea wau e koho ai i ka hōʻailona kuhili ʻole kūpono (304(L)/316(L)/420(C)/440(C))?He aha nā ʻokoʻa nui ma waena o 300 a me 400 moʻo pōlele kila kila?
A: No ke koho ʻana i ke kila kila kūpono no nā pōpō kila kila, pono mākou e ʻike pono i nā waiwai o kēlā me kēia brand a me ka hoʻohana ʻana i nā pōpō.Hiki ke hoʻokaʻawale ʻia nā pōpō kila kila maʻamau i ʻelua pūʻulu: 300 series a me 400 series.
300 moʻo "austenitic" kuhiliʻole kila poepoe he oi chromium a me nickel mau mea a me ka theoretically non-magnetic (maoli loa haʻahaʻa-magnetic. holoʻokoʻa non-magnetic pono a me ka wela wela.).ʻO ka mea maʻamau, hana ʻia lākou me ka ʻole o ke kaʻina hana wela.Ua ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o ka moʻo 400 (ʻoiaʻiʻo, ʻo ke kūpaʻa kiʻekiʻe loa o ka hui kuhili. ʻOiai ʻo nā pōpō moʻo 300 he kūpaʻa kūʻokoʻa, akā naʻe, hōʻike nā pōpō 316 a me 304 i ke kūʻē ʻokoʻa i kekahi mea. No nā kikoʻī hou aku, e ʻoluʻolu e nānā i nā ʻaoʻao. o na poepoe kila kuhilihi like ole) .He liʻiliʻi lākou, no laila hiki ke hoʻohana ʻia no ka hoʻohana ʻana i ka sila.400 moʻo pōpō kila kuhiliʻole i loaʻa i ke kalapona ʻoi aku ka ikaika a ʻoi aku ka paʻakikī.Hiki iā lākou ke maʻalahi i ka wela e like me nā pōpō kila chrome a i ʻole nā ​​pōpō kila kalapona e hoʻonui i ka paʻakikī.Hoʻohana maʻamau ʻia nā pōpō stainless steel 400 no nā noi e koi ana i ka wai-kūʻē, ka ikaika, ka paʻakikī a me ke kūpaʻa ʻaʻahu.

Q: Pehea kāu hōʻoia maikaʻi?
A: ʻO nā pōpō a pau i hana ʻia he 100% i hoʻokaʻawale ʻia e ka pahu hoʻokaʻawale a nānā ʻia e ka mea ʻike defect surface photoelectric.Ma mua o ka hoʻopaʻa ʻana i nā laʻana, e hoʻouna ʻia nā pōpō mai ka hailona no ka nānā hope ʻana e nānā i ke ʻano ʻala, ka poepoe, ka paʻakikī, ka ʻokoʻa, ka ukana a me ka haʻalulu e like me ka maʻamau.Inā hoʻokō ʻia nā koi a pau, e hana ʻia kahi hōʻike nānā no ka mea kūʻai.Hoʻolako ʻia kā mākou hale hana paʻakikī me nā mīkini kikoʻī kiʻekiʻe a me nā mea hana: Rockwell hardness tester, Vickers hardness tester, crushing load machine, roughness meter, roundness meter, diameter comparator, metallographic microscope, vibration ana instrument, etc.
