A105 yog Asmeskas tus qauv ASTM tus lej, thiab A sawv cev rau cov qauv carbon zoo tib yam.
Txheem lub npe: carbon steel forgings rau cov yeeb nkab Cheebtsam.Vim tias tsuas yog ib qho carbon steel forging tau teev nyob rau hauv tus qauv no, A105 yog txawm tias carbon steel qib ntawm forging.A105 kuj yog cov khoom siv code, uas belongs rau cov hlau tshwj xeeb thiab yog cov hlau forged txias.A105 yog cov hlau tsis tshua muaj hlau forging, zoo ib yam li 20 steel.Muaj ob tus qauv, ib qho yog Asmeskas tus qauv ASTM A105 / A105M Carbon Steel Forgings rau Piping Cheebtsam, thiab lwm yam yog Suav tus qauv GB / T12228-2006 Cov Txheej Txheem Txheej Txheem rau Carbon Steel Forgings rau General Purpose Valves.
Cov ntsiab lus C: ≤ 0.35 Si: ≤ 0.35 Mn: 0.6-1.05 S: ≤ 0.050 P: ≤ 0.040, Cu ≤ 0.4 Ni ≤ 0.4 Mo ≤ 0.12 V ≤ 0.08 Cr ≤ 0.3
Cov khoom siv tshuab yog nyob nruab nrab ntawm No. 20 forged steel thiab 16Mn forged steel.
