Aplikasi Plat Baja Tahan Abrasi
● piring AR235 dimaksudaké kanggo aplikasi nyandhang Moderate ngendi nawakake resistance nyandhang apik relatif kanggo baja karbon struktural.
● AR400 minangka piring baja tahan abrasi premium sing diolah kanthi panas lan ngetokne hardening. Peningkatan kemampuan mbentuk lan kawin.
● AR450 minangka piring tahan abrasi sing digunakake ing macem-macem aplikasi ing ngendi kekuatan sing luwih gedhe dikarepake ngluwihi AR400.
● piring AR500 cocok kanggo pertambangan, kehutanan lan aplikasi construction.
● AR600 digunakke ing wilayah dhuwur-nyandhang kayata aman agregat, pertambangan, lan Pabrik buckets lan nyandhang awak.
Plat baja tahan abrasi (AR) biasane digawe ing kondisi sing digulung. Jinis / gelar produk piring baja iki wis dikembangake khusus kanggo umur layanan sing dawa ing kahanan sing angel. Produk AR cocok kanggo macem-macem aplikasi ing wilayah kayata pertambangan / quarrying, conveyor, penanganan material lan construction, lan bumi obah. Desainer lan operator tanduran milih baja piring AR nalika ngupayakake kanggo ngluwihi umur layanan komponen kritis, lan ngurangi bobot saben unit sijine menyang layanan. Mupangat nggunakake baja piring tahan nyandhang ing aplikasi sing kena pengaruh lan / utawa kontak geser karo bahan abrasif banget.
Piring baja paduan tahan abrasive umume menehi resistensi sing apik kanggo abrasi geser lan impact. Isi karbon dhuwur ing alloy nambah atose lan kateguhan saka baja, dadi bahan becik kanggo aplikasi sing mbutuhake impact dhuwur utawa resistance abrasion dhuwur. Sampeyan bisa njaluk atose dhuwur karo baja karbon dhuwur, lan baja bakal duwe resistance apik kanggo seng nembus. Nanging, tingkat nyandhang bakal cepet dibandhingake karo piring alloy panas dianggep amarga baja karbon dhuwur iku brittle, supaya partikel bisa luwih gampang ambruk saka lumahing. Akibaté, baja karbon dhuwur ora digunakake kanggo aplikasi nyandhang dhuwur.
