420J1 420J2 ʻāpana kila kila
Wehewehe Pōkole:
ʻO nā ʻāpana kila kila 420J1 a me 420J2 ʻelua mau ʻano kila kila maʻamau e pili ana i ka moʻo kila kila martensitic. Loaʻa iā lākou kekahi mau ʻokoʻa i ke ʻano kemika a me nā ʻano. Eia kahi ʻike pōkole o kēlā me kēia:
1. ʻĀpana kila kila 420J1: He kila kila kalapona haʻahaʻa ʻo 420J1 me ka paʻakikī a me ka ikaika kiʻekiʻe. ʻO kona ʻano kemika maʻamau e pili ana i kahi 0.16-0.25% kalapona, ma kahi o 1% chromium, a me nā ʻāpana liʻiliʻi o ka molybdenum. Hāʻawi ʻo 420J1 i ke kūpaʻa maikaʻi i ka pala, ka hana ʻoki, a me nā waiwai wili. Hoʻohana pinepine ʻia no ka hana ʻana i nā pahi, nā mea hana ʻoki, nā ʻāpana mīkini, a me kekahi mau noi pale i ke komo ʻana.
2. ʻĀpana kila kila 420J2: He kila kila kalapona waena ka 420J2 me ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu. Loaʻa i kona ʻano kemika ma kahi o 0.26-0.35% kalapona a me kahi o 1% chromium. ʻOi aku ka nui o ke kalapona o ka 420J2 i hoʻohālikelike ʻia me 420J1, e hopena ana i ka paʻakikī a me ka hana ʻoki. Hoʻohana pinepine ʻia no ka hana ʻana i nā pahi, nā pahi, nā mea hana ʻoki, nā pūnāwai, a me kekahi mau ʻāpana mīkini.
