I-AISI 4140 SCM440 DIN 42CrMo4 1.7225 i-Forged Steel Bar eRound Bar
Iinkcukacha zeMveliso
I-AISI 4140 ichazwa njengensimbi ephantsi ye-alloy ene-1% ye-Cr-Mo njengento eyomelezayo ye-alloy elements.Xa ithelekiswa ne-AISI 4130, inomxholo ophezulu wekhabhoni kunye nokulinganisela okuhle kwamandla, ukuqina, ukukrazula kunye nokuchasana kwempembelelo kunye nobuchule bokunyanga ukushisa, kodwa ihlwempu kwiimpawu zobuchule be-weld.AISI 4140 inikezelwa ngokubanzi kwimeko ecinyiweyo kunye nobushushu kunye nobunzima be-28-32HRC.
I-4140 inamandla aphezulu, amandla okuqina, ukuqina, kunye nokuguqulwa ngexesha lokucima.Inamandla aphezulu okurhubuluza kunye namandla okunyamezela kumaqondo obushushu aphezulu.Isetyenziselwa ukuvelisa i-forgings efuna amandla aphezulu kunye namacandelo amakhulu acinyiweyo kunye nobushushu kunentsimbi ye-4135, njengeegiya ezinkulu ze-locomotive traction, i-booster transmission gears, i-axles yangasemva, ii-axles zokudibanisa kunye neziqeshana zasentwasahlobo ezilayishwe kakhulu.
