Kusiyana pakati pa chitsulo chaulere 1215 ndi 11SMn30 chitsulo

Chitsulo chodulira chaulere chimatanthawuza chitsulo cha alloy chomwe chimawonjezera kuchuluka kwa chinthu chimodzi kapena zingapo zaulere monga sulfure, phosphorous, lead, calcium, selenium, tellurium, etc.Ndi makina, kuthamanga kwambiri komanso kulondola kwa kudula, ndikofunikira kwambiri kuti zitsulo zikhale ndi makina abwino, omwe amagwiritsidwa ntchito makamaka pokonza makina odulira okha.Zotsatirazi zikuyang'ana pa kusiyana pakati pa 1215 chitsulo chodula chaulere ndi chitsulo cha 11SMn30 chaulere.

1215 Chitsulo Chodula Chaulere

1215 ndi mtundu wachitsulo chosavuta kudula mu American ASTM/AISIBI standard series.Chitsulo cha 1215 chaulere ndi chinthu chokonda zachilengedwe chomwe chilibe lead kapena zinthu zovulaza chilengedwe.Ili ndi zida zabwino zodulira ndipo ndiyoyenera ma shafts onse a electroplating, zida zodulira, ndi mbali zonse.

1215 chitsulo chodulira chaulere chimagwiritsidwa ntchito makamaka popanga zida, magawo owonera, magalimoto, zida zamakina, ndi makina ena osiyanasiyana omwe ali ndi zofunika kwambiri pakukula komanso kusalala chifukwa cha kupsinjika pang'ono.Ili ndi zofunikira zokhwima kuti zikhale zolondola komanso zosalala, koma zofunikira zochepa zamakina, monga magiya, mitsinje, mabawuti, mavavu, ma bushings, zikhomo, mafupa a chitoliro, ma cushions ampando wa masika ndi zomangira zida zamakina, pulasitiki kupanga nkhungu Opaleshoni ndi mano , ndi zina.

11SMn30 chitsulo chodula chaulere

11SMn30 (1.0715) ndi German muyezo ufulu kudula zitsulo kalasi, amene sulfure phosphorous gulu mkulu sulfure, otsika pakachitsulo ufulu kudula structural chitsulo
