AISI 4140 SCM440 DIN 42CrMo4 1.7225 Forged Alloy Steel Round Bar
Detail Produk
AISI 4140 ditetepake minangka baja paduan rendah sing nduweni 1% Cr-Mo minangka unsur paduan penguat. Dibandhingake karo AISI 4130, nduweni isi karbon sing luwih dhuwur kanthi imbangan kekuatan, kateguhan, abrasi lan impact resistance lan kemampuan perawatan panas, nanging miskin ing karakteristik kemampuan weld.AISI 4140 umume diwenehake ing kahanan quenched lan tempered karo atose 28-32HRC.
4140 nduweni kekuatan dhuwur, kemampuan harden, kateguhan, lan deformasi sajrone quenching.Nduweni kekuatan creep dhuwur lan kekuatan toleransi ing suhu dhuwur.Digunakake kanggo manufaktur forgings sing mbutuhake kekuatan sing luwih dhuwur lan bagean quenched lan tempered luwih gedhe saka 4135 baja, kayata Gir gedhe kanggo doyo tarik lokomotif, Gir transmisi booster, as mburi, rod nyambungake lan klip spring sing akeh banget dimuat.
