Product Application

Kugwiritsa ntchito 42CrMo aloyi chitoliro chosasunthika: chitsulo chapadera chomwe chimagwiritsidwa ntchito pamilatho ndi "42CrMo", chitsulo chapadera chazitsulo zamagalimoto ndi "42CrMo", ndipo chitsulo chapadera chazotengera ndi "42CrMo".Chitsulo choterechi chimapangitsa kuti zitsulo zisamayende bwino posintha zomwe zili mu carbon (c).Choncho, malinga ndi carbon okhutira, mtundu uwu wa zitsulo akhoza kugawidwa mu: low carbon steel -- carbon zili zambiri zosakwana 0,25%, monga 10 ndi 20 zitsulo;Chitsulo chapakati cha carbon -- mpweya wa carbon nthawi zambiri umakhala pakati pa 0.25 ndi 0.60%, monga 35 ndi 45 zitsulo;High carbon steel -- mpweya wa carbon nthawi zambiri umaposa 0.60%.Chitsulo chamtunduwu sichimagwiritsidwa ntchito popanga mapaipi achitsulo.

Kugwiritsa Ntchito
Oyenera kupanga nkhungu zazikulu ndi zapakati zapulasitiki zomwe zimafuna mphamvu ndi kulimba.
