AISI 4140 SCM440 DIN 42CrMo4 1.7225 Forged Alloy Steel round Bar
Product Detail
AISI 4140 definitur ad mixturam ferri humilem, quae 1% Cr-Mo habet ad mixturam elementorum corroborandam. Comparata cum AISI 4130, superiorem carbo contentam habet cum bona statera virium, duritiem, abrasionis et ictum resistendi et caloris facultates curandi, sed pauperes in concubitu facultates indoles. AISI 4140 plerumque suppletur in condicione exstincto et temperato cum duritia 28-32HRC.
4140 Virtutem habet altam, facultatem obdurationis, duritiem, deformationem in exstinguendo.Subrepere est altum robur et patientiae robur in calidis.Usus est ad malleos fabricandos qui superiores vires requirunt et sectiones maiores exstinctas et temperatas quam 4135 ferro, ut anni magni ad tractionem motivum, anni cursus transmissionis, axes posteriores, virgas conectentes et tondeos vere oneratos.
