AISI SAE 4130 4140 4145H Steel Round Bar Hollow Rod
Fitur
Bar baja 4130 4135 4140 4145H minangka baja paduan karbon rendah.Iki kalebu paduan Chrome-Molly sing ngemot kromium lan molybdenum minangka agen penguat.
4130 bar baja bunder nduweni kemampuan kerja sing apik, deformasi pangolahan minimal, lan resistensi lemes banget.Iku belongs kanggo kategori medium kanggo baja kemampuan harden dhuwur.Sawise perawatan panas, 4140 nduweni kekuatan sing apik lan sifat mekanik sing komprehensif, kemampuan proses sing apik, lan ngasilake dhuwur.Suhu layanan yaiku 427 derajat Celsius.
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.
