Los xyuas kom meej tias L245cov kav dejsteel yeeb nkab muaj zog dua qaug zog, compressive zog, nto hardness, thiab ntev kev pab cuam lub neej, ntau yam uas tsis yog-metallic inclusions xws li oxide inclusions, sulfide inclusions, thiab point inclusions nyob rau hauv cov hlau yuav tsum nruj me ntsis tswj nyob rau hauv ntau yam;Lub inhomogeneity ntawm ntau yam carbide nyob rau hauv steel (xws li carbide liquefaction, strip carbide, band carbide, thiab network carbide, thiab lwm yam) yuav tsum tau tswj nyob rau hauv lub theem.

Lub thickness ntawm decarbonized txheej nyob rau saum npoo ntawm lub tiav bearing steel tom qab ua kub yuav tsum tau txo;lub macroscopic low-magnification qauv ntawm cov hlau yuav tsum yog feem ntau xoob.Lub chaw poob, thiab theem ntawm kev cais yuav tsum me me.Subcutaneous npuas, shrinkage qhov, Inclusions, thiab tawg.Cov hlau annealed yuav tsum muaj cov qauv zoo ib yam thiab zoo spherical pearlite qauv.

1. Qhov yuav tsum tau ua

Txhawm rau kom ntseeg tau tias qhov chaw ntawm cov kabmob tsis muaj qhov tsis xws luag, qhov chaw ntawm cov kabmob steel yuav tsum du thiab tsis muaj qhov tsis xws luag xws li tawg, nti, folding, pitting, thiab khawb.

2. Qhov yuav tsum tau muaj

Hauv kev ua tiav ntawm cov kabmob steel, kom raug txiav cov ntaub ntawv raw thiab ua tiav rau hauv qhov xav tau qhov loj me, qhov tseeb qhov tseeb ntawm cov kabmob steel cov khoom tseem yuav tsum tau nruj me ntsis, thiab cov duab ntawm cov khoom tiav kuj yuav tsum tau ncaj.
