Isicelo somkhiqizo

Ukusetshenziswa kwepayipi elingenamthungo elingu-42CrMo: insimbi ekhethekile esetshenziselwa amabhuloho yi-"42CrMo", insimbi ekhethekile yamagida ezimoto yi-"42CrMo", kanti insimbi ekhethekile yemikhumbi yokucindezela ithi "42CrMo".Lolu hlobo lwensimbi luthuthukisa izakhiwo zensimbi ngokulungisa okuqukethwe kwekhabhoni (c).Ngakho-ke, ngokokuqukethwe kwekhabhoni, lolu hlobo lwensimbi lungahlukaniswa lube: insimbi ye-carbon ephansi -- okuqukethwe kwekhabhoni ngokuvamile kungaphansi kuka-0.25%, njengensimbi engu-10 no-20;I-Medium carbon steel -- okuqukethwe kwekhabhoni kuvamise ukuba phakathi kuka-0.25 no-0.60%, njengensimbi engama-35 no-45;I-high carbon steel -- okuqukethwe kwekhabhoni kuvamise ukuba kukhulu kuno-0.60%.Lolu hlobo lwensimbi ngokuvamile alusetshenziselwa ukwenza amapayipi ensimbi.

Uhlelo lokusebenza olujwayelekile
Ifanele ukwenza isikhunta sepulasitiki esikhulu nesiphakathi nendawo esidinga amandla athile nokuqina.
