Awọn iye ti erogba akoonu jẹ ẹya pataki itọkasi fun awọn idagbasoke ti alurinmorin lakọkọ. Bi akoonu erogba ṣe pọ si, agbara ati lile n pọ si, lakoko ti ṣiṣu ati lile dinku, lakoko ti aapọn naa n pọ si. Ni ibatan sọrọ, kekere akoonu erogba, weldability dara julọ, nitorinaa, akoonu erogba jẹ boṣewa fun ṣiṣe idajọ iṣoro ti alurinmorin erogba, ati awọn ilana alurinmorin oriṣiriṣi yẹ ki o gba fun oriṣiriṣi akoonu erogba.

Aṣayan awọn ohun elo alurinmorin irin erogba tẹle ilana ti “agbara dogba”
1. Kekere erogba irin (eyiti a mọ bi ìwọnba irin)
Awọn ipele irin ti o wọpọ gẹgẹbi Q235 (ti a mọ ni kutukutu bi A3 irin), Q255, ati bẹbẹ lọ, ni gbogbogbo ko ṣe awọn igbese pataki nigba alurinmorin, boya preheating tabi postheating.
2. Alabọde erogba, irin
Irin ti o wọpọ bi 30 #, 45 #, ati bẹbẹ lọ, 45 # jẹ ohun elo fun iṣelọpọ awọn abẹfẹlẹ ati awọn faili, o dara julọ lati lo awọn ohun elo alurinmorin kekere-hydrogen ti o ni idena kiraki ti o dara, preheating 100-200 °C; Ti ko ba rọrun lati ṣaju, Cr-Ni austenitic alagbara, irin alurinmorin ohun elo le yan.
3. Ga erogba irin
Awọn onipò irin ti o wọpọ bii 60Si2Mn, T8, T10 ati bẹbẹ lọ. 60Si2Mn jẹ irin orisun omi ti o jẹ aṣoju, ni gbogbogbo ko ṣe itọju alurinmorin, ti a lo pupọ julọ bi alurinmorin, yẹ ki o jẹ 250-350 °C preheating, alurinmorin gbọdọ wa ni hammered lati yọ aapọn kuro, ati 650 °C itọju igbona lẹhin-ooru, tun le yan Cr-Ni austenitic alagbara, irin alurinmorin ohun elo
