AISI 4140 SCM440 DIN 42CrMo4 1.7225 Forged Alloy Steel Round Bar

Ua wehewehe ʻia ʻo AISI 4140 ma ke ʻano he kila kila haʻahaʻa nona ka 1% Cr-Mo e like me ka hoʻoikaika ʻana i nā mea hoʻohuihui. ʻilihune i ka weld hiki i nā hiʻohiʻona.AISI 4140 ka mea maʻamau i hoʻolako ʻia i ke kūlana quenched a me ka paʻakikī 28-32HRC.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

He ikaika kiʻekiʻe ka 4140, hiki ke paʻakikī, paʻakikī, a me ka deformation i ka wā e kinai ana.Loaʻa iā ia ka ikaika kolo kiʻekiʻe a me ka ikaika hoʻomanawanui i nā wela kiʻekiʻe.Hoʻohana ʻia no ka hana ʻana i nā forgings e koi ai i ka ikaika kiʻekiʻe a me nā ʻāpana hoʻopau a me nā ʻāpana ʻoi aku ka nui ma mua o ke kila 4135, e like me nā mīkini nui no ka locomotive traction, booster transmission gears, hope axles, connecting rods a me nā kiʻi puna i hoʻouka nui ʻia.
