S31803 Stenles Sil
Steinles Steel S31803 em i wanpela dupleks steinles stiel i gat bikpela luksave na ol i luksave long en we i bungim ol gutpela samting bilong ol austenititik na feritik steinles stiel, na i givim wanpela spesel balens bilong bikpela strong, strongpela korosen resistens, na gutpela weldabiliti. Dispela dupleks aloi em i hap bilong 2205 seris, we i gat mak bilong en inap olsem 50/50 austenitic-}ritik maikrostraksa, we i save givim strongpela pefomens long ol agresif envairomen skelim wantaim planti standet austenitiks gret.

Samting
S31803, wanpela tupela-feis steinles stiel, i gat dinau long straksa na ol samting bilong en long wanpela kemikel komposesen ol i bin disainim stret. Kromiam (21{6}}3%) i kamapim wanpela protektiv oksait leit bilong korosen resistens, nikel (4.5-6.5%) i mekim strong bilong austenitik hap, na molibdenam (2.5-3.5%) i strongim resistens long pitting na kruvais korosen, moa yet long klorait-rich kondisen. Naitrojen (0.08-0.20%) i save strongim wok bilong marasin bilong helpim ol man, na ol i save bosim kabon, manganis, silikon, fosforas, na salfa bilong lukautim gut ol samting bilong maikrostraksel.
Mekanikli, S31803 i gutpela tru wantaim minimam tensil strong bilong 620 MPa na givim strong bilong 450 MPa, klostu tupela taim bilong 304 o 316, tasol em i holim yet 25% elongasen bilong wokim. Bikpela strong bilong en-long-weit resio i stret long hevi bilong en-}sensitiv aplikesen.
Korosen resistens em i strong bilong S31803. Wetem wan PREN blong 32-36, hem i agensem jenerol, pitting, mo krevis korosen long ol solwota, ol brine, mo ol indastri kemikol we i moa gud bitim 316.
