420J1 420J2 kaula hao kuhiliʻole
ʻO ka wehewehe pōkole:
ʻO 420J1 a me 420J2 mau ʻāpana kila kila ʻelua mau ʻano maʻamau o nā mea kila kila i pili i ka moʻo kila kila martensitic. Loaʻa iā lākou kekahi mau ʻokoʻa i ka haku melemele a me nā ʻano. Eia kahi ʻike pōkole o kēlā me kēia:
1. 420J1 kuhiliʻole kila: 420J1 mea haʻahaʻa-carbon kuhiliʻole kila me kiʻekiʻe paakiki a me ka ikaika. ʻO ka hui kemika maʻamau ka 0.16-0.25% kalapona, ma kahi o 1% chromium, a me ka liʻiliʻi o ka molybdenum. Hāʻawi ʻo 420J1 i ka pale ʻana i ka corrosion maikaʻi, ka hana ʻoki ʻana, a me nā waiwai wili. Hoʻohana maʻamau ia no ka hana ʻana i nā pahi, nā mea hana ʻokiʻoki, nā ʻāpana mechanical, a me kekahi mau mea hoʻohana pale.
2. 420J2 mea kila kuhiliʻole: 420J2 mea he medium-carbon kuhiliʻole kila me kiʻekiʻe paakiki a me ka lole pale. Aia ma kahi o 0.26-0.35% kalapona a ma kahi o 1% chromium kona haku mele. Loaʻa i ka 420J2 kahi mea kalapona kiʻekiʻe ma mua o 420J1, e hopena i ka hoʻonui ʻana i ka paʻakikī a me ka ʻoki ʻana i ka hana. Hoʻohana pinepine ʻia no ka hana ʻana i nā pahi, nā lau, nā mea hana ʻoki, nā punawai, a me kekahi mau ʻāpana mechanical.
