420J1 420J2 umurongo wibyuma
Ibisobanuro bigufi:
420J1 na 420J2 imirongo yicyuma ni ubwoko bubiri bwibikoresho byuma bidafite ibyuma bya martensitike idafite ibyuma.Bafite itandukaniro mubigize imiti nibiranga.Dore incamake muri buri:
1. 420J1 ibyuma bitagira umuyonga: 420J1 nicyuma gike-karuboni nkeya idafite ibyuma nimbaraga zikomeye.Ibigize imiti bisanzwe birimo karubone 0.16-0.25%, chromium hafi 1%, hamwe na molybdenum nkeya.420J1 itanga uburyo bwiza bwo kurwanya ruswa, kugabanya imikorere, hamwe no gusya.Bikunze gukoreshwa mugukora ibyuma, ibikoresho byo kubaga, ibice byubukanishi, hamwe na porogaramu zidashobora kwambara.
2Ibigize imiti bisanzwe birimo karubone 0.26-0.35% na chromium hafi 1%.420J2 ifite karubone nyinshi ugereranije na 420J1, bigatuma ubukana bwiyongera no kugabanya imikorere.Ikoreshwa cyane mugukora ibyuma, ibyuma, ibikoresho byo kubaga, amasoko, nibice bimwe na bimwe bya mashini.
