Hot Rolled Alloy Steel silig Rod SAE1018
Hordhaca caadiga ah
Usha silig SAE1018 waxay raacdaa xeerarka magacaabidda ee Machadka Birta iyo Birta Maraykanka (AISI), halkaasoo "10" ka dhigan tahay birta manganese ee carbon iyo "18" waxay ka dhigan tahay celceliska kaarboonka ee ku saabsan 0.18% (kuwa kaarboonku wuxuu kaloo noqon karaa inta u dhaxaysa 0.15% iyo 0.25%). Waxaa sidoo kale loo yaqaannaa birta qaab dhismeedka kaarboonka caadiga ah ama birta qaab dhismeedka daawaha, iyo heerka la fuliyay waa ASTM ama SAE J403-2001.
Halabuurka kiimikada
Halabuurka kiimikada ee usha siliga birta SAE1018 inta badan waxaa ka mid ah birta (Fe), carbon (C), manganese (Mn), Silicon (Si) iyo qadar yar oo fosfooraska (P), baaruud (S) iyo xubno kale. Kala duwanaanshaha ka kooban kiimikada gaarka ah waa sida soo socota:
Kaarboon (C): 0.15% ~ 0.25%
Manganese (Mn): 0.60% ~ 1.00%
Silikoon (Si): 0.15% ~ 0.35%
Fosfooraska (P): ≤0.04% (xogta qaar ayaa tilmaamaya ≤0.035%)
Sulfur (S): ≤0.05%
Intaa waxa dheer, waxa kale oo laga yaabaa inay ku jiraan raadad cadad ah chromium (Cr), copper (Cu), nikkel (Ni) iyo molybdenum (Mo), laakiin waxa ku jira inta badan waa hooseeyaan.
Guryaha makaanikada
Usha silig birta duuban ee kulul SAE1018 waxay leedahay sifooyin farsamo oo aad u wanaagsan, oo ay ugu badan yihiin:
Xoog xajin: ≥450MPa (xogta qaarkood ayaa tilmaamaya ilaa 410MPa, qiimaha gaarka ah waa kala duwanaan karaa iyadoo ay sabab u tahay Dufcadaha kala duwan ama hababka processing).
Awoodda wax-soo-saarka: ≥275MPa
Ballaarinta: ≥24%, taasoo siinaya caag wanaagsan iyo awoodda qallafsanaan.
Hoos u dhaca qaybaha: ≥50%
Adag: Marka aan kulaylka la daweyn, engegnaanta guud ahaan kama badna 197HB; daawaynta kulaylka (sida caadiga ah 910 ℃) waxay wanaajin kartaa adkaanteeda iyo xooggeeda.
| Heerka | AISI,ASTM,BS,DIN,GB,JIS |
| Tilmaamaha cabbirka | 5.5MM 6.5MM 7.0MM 8.0MM 9.0MM 10MM 12MM 14MM 16MM |
| Miisaanka / Gariiradda | 2 tan |
Xaaladda gaarsiinta iyo daaweynta kulaylka
Usha siliga birta ah ee duuban ee kulul SAE1018 waxaa badanaa la geeyaa xaalad daawaynta kulayl la'aan ama kuleyl la'aan (waxyeelitaan, caadiyeynta ama heerkulka heerkulka sare). Haddii daaweynta kuleylka loo baahan yahay, waa in lagu tilmaamaa heshiiska. Haddii aan la tilmaamin, waxaa la geyn doonaa iyada oo aan la daaweyn kulayl. Caadiyan waxay hagaajin kartaa waxqabadka goynta ee usha siliga birta kaarboon SAE1018 iyo hagaajinta waxqabadkooda dhamaystiran.
