1.0503, S45C, G10450, AISI 1045
GENERAL CHARACTERISTIS
1045 / C45 steel yog txhais ua cov pa roj carbon nruab nrab uas muaj 0.4% -0.5% Carbon. Nws muaj qhov zoo weldability, zoo machinability, siab zog thiab cuam tshuam cov khoom, tab sis tsis tshua muaj hardenability vim tsis muaj cov ntsiab lus alloying haum.

Nqe lus piav qhia C45 yog ib qho nruab nrab carbon steel yog siv thaum muaj zog thiab hardness ntau dua li nyob rau hauv "raws li dov" mob. Qhov loj loj qhov tseeb, ncaj thiab concentricity ua ke kom txo qis hnav hauv kev siv ceev ceev. Tig, av thiab polished. Daim ntaub ntawv quenched thiab tom qab tempered steel rau screws, forgings, log log, ncej, mob, axes, riam, ntoo ua hauj lwm xyaum, rauj, thiab lwm yam.

Mos Annealing Kub rau 680-710 ° C, maj mam txias hauv qhov cub. Qhov no yuav ua rau qhov siab tshaj plaws Brinell hardness ntawm 207. Normalizing Normalizing kub: 840-880 ° C/air. Hardening Harden los ntawm qhov kub ntawm 820-860 ° C C ua raws li dej los yog roj quenching. Tempering kub: 550-660 ° C/air. Mechanical Properties hauv Quenched + Tempered Kho
