Cov khoom siv siab thiab nruab nrab rau kev lag luam tsheb thiab kev tsim kho tshuab - shafts, connecting rods, crankshafts, screws, thiab lwm yam.

Cov khoom siv lub cev (avetus nqi npau taws) ntawm qhov kub thiab txias ib puag ncig

Modulus ntawm elasticity [103 x N/mm2]: 210

Qhov Ceev [g/cm3]: 7.80

Kev Ua Kom Mos Mos

Ua kom sov txog 680-720oC, maj mam txias hauv lub cub tawg. Qhov no yuav ua rau muaj qhov siab tshaj plaws Brinell hardness ntawm 241.

Kev ua kom zoo li qub

Kub: 840-880oC.

Kev ua kom tawv

Ua kom tawv ntawm qhov kub ntawm 820-860oC ua raws li roj lossis dej quenching.

Kev ua kom sov

Kub kub: 540-680oC.
