Naha anjeun terang bédana antara baja karbon sareng baja alloy?
Baja karbon:utamana nujul kana sipat mékanis gumantung kana eusi karbon tina baja, sarta umumna teu nambahan loba elemen alloying baja, sok disebut baja karbon polos atawa baja karbon. Baja karbon, ogé katelah baja karbon, eusi karbon WC kirang ti 2% alloy karbon beusi.
Baja karbon salian umumna ngandung jumlah leutik silikon, mangan, walirang, fosfor bisa dibagi nurutkeun pamakéan baja karbon baja struktural karbon, baja alat karbon jeung baja struktural motong bébas tilu baja struktural karbon dibagi kana baja struktural jeung baja struktural mesin, nu bisa dibagi kana baja karbon low (WC ≤ 0,25%), baja karbon sedeng (WC 0,25% - 0,6%) jeung steels karbon tinggi (WC> 0,6%).
Numutkeun eusi fosfor jeung walirang, steels karbon bisa dibagi kana baja karbon biasa (fosfor jeung walirang leuwih luhur), steels karbon kualitas luhur (fosfor jeung walirang leuwih handap) baja kualitas luhur (fosfor, walirang handap).
Baja paduan:dumasar kana baja karbon, hiji atawa leuwih elemen alloying ngahaja ditambahkeun pikeun ngaronjatkeun serviceability sarta kinerja prosés tina alloy basis beusi disebut alloy steel. Baja paduan ngarujuk kana baja anu ngandung silikon sareng mangan salaku unsur paduan atanapi unsur deoxidizing, unsur paduan sanés sapertos kromium, nikel, molibdenum, vanadium, titanium, tambaga, tungsten, aluminium, kobalt, niobium, zirconium sareng unsur sanésna, sareng sababaraha ogé. ngandung sababaraha unsur non-logam (kayaning boron, nitrogén, jsb) baja.
Numutkeun jumlah elemen alloying dina baja, tapi ogé bisa dibagi kana baja alloy low, alloy sedeng jeung baja alloy tinggi.
Komposisi kimia béda:
(1) baja karbon: baja karbon Low (C≤0.25%); baja karbon sedeng (C≤0.25 ~ 0.60%); Baja karbon luhur (C≤0,60%).
(2) baja alloy: baja alloy Low (total eusi elemen alloying ≤ 5%); baja alloy sedeng (total eusi alloying elemen> 5 ~ 10%); Baja alloy tinggi (total eusi elemen alloying> 10%.
Keuntungan baja karbon:
Baja karbon boga kakuatan tinggi, ductility jeung kateguhan, béaya rendah, dipaké dina mesin beurat pikeun pembuatan bagian beban beurat. Bisa diala ku perlakuan panas sipat mékanis hadé matak.
Keunggulan Alloy Steel:
Salian beusi dina elemen baja ngan ngandung baja karbon, baja karbon, silikon séjén, walirang, fosfor jeung pangotor lianna. Salian unsur séjén kromium, mangan, molybdenum, titanium, tungsten, vanadium, niobium, boron, silikon jeung baja alloy nikel pikeun ngahontal sipat nu dipikahoyong kayaning suhu luhur, élastisitas tinggi, résistansi abrasion, kakuatan tinggi, kateguhan tinggi jeung saterusna. asup.
