Papa kila kila 420No ke kila kila martensitic, nona kekahi kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa i ka pala, paʻakikī kiʻekiʻe, a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o nā ʻano kila kila ʻē aʻe. He kūpono ka pepa kila kila 420 no nā ʻano mīkini kikoʻī āpau, nā bearings, nā mīkini uila, nā lako, nā mea kani, nā mika, nā kaʻa, nā mīkini hale, a pēlā aku. Hoʻohana nui ʻia ke kila kila 420 i ka hana ʻana i nā ʻāpana e kū i ka lewa, ka mahu wai, ka wai a me ka oxidative acid corrosion.
Kina 420 pepa kila kila maʻamau hoʻokō:
GB/T 3280-2015 “Papa kila kila ʻōwili anu a me ka ʻāpana kila”
GB/T 4237-2015 “Papa kila kila ʻōwili wela a me ke kaula kila”
GB/T 20878-2007 "Nā pae kila kila a me ke kila kūpaʻa wela a me ka hoʻohuihui kemika"
420 papa kila kila ma Kina:
Nā māka hou: 20Cr13, 30Cr13, 40Cr13.
Nā papa kahiko: 2Cr13, 3Cr13, 4Cr13.
Nā ʻano a me nā hoʻohana o ka pepa kila kila Kina 420:
20Cr13 kila kila: paʻakikī kiʻekiʻe i ke kūlana pio, kūpaʻa maikaʻi i ka pala. No nā pahi turbine mahu.
30Cr13 kila kila: ʻOi aku ka paʻakikī ma mua o 20Cr13 ma hope o ka hoʻopau ʻana, hoʻohana ʻia e like me nā mea ʻokiʻoki, nā nozzles, nā noho valve, nā valves, a pēlā aku.
40Cr13 kila kila: ʻOi aku ka paʻakikī ma mua o 30Cr13 ma hope o ka hoʻopau ʻana, hoʻohana ʻia e like me nā mea ʻokiʻoki, nā nozzles, nā noho valve, nā valves, a pēlā aku.
