35CrMnSiA ke tšepe e nang le alloy e tlase e matla haholo. Ka mor'a phekolo ea mocheso, e na le lisebelisoa tse ntle tsa mochine, matla a phahameng, boima bo lekaneng, boima, weldability (preheating pele ho tjheseletsa), le sebopeho sa ho sebetsa, empa e na le khanyetso e ntle ea kutu le khanyetso e tlaase ea oxidation, e atisang ho sebelisoa ka mor'a hore mocheso o fokotsehe kapa o fokotsehe. Matla a phahameng a tingoeng le a futhumetseng a tšepe ea sebopeho. E na le matla a phahameng le ho tiea, boima bo phahameng, polasetiki ea deformation e batang e mahareng, le ts'ebetso e ntle ea ho itšeha. Ho na le tšekamelo ea ho halefa brittleness, 'me matla a ho fetela ha a na matla. Ts'ebetso ea tjheseletsa e betere, empa ha botenya bo feta 3mm, e lokela ho futhumatsoa pele ho 150 ℃, 'me kalafo ea mocheso e hlokahala kamora ho cheselletsa. Hangata e sebelisoa ka mor'a ho nosetsa.
