Akasaukidwe osapanga dzimbiri pa> 80% ya kumwa ma duplex, Super Pumplex ndi Hyper Pulex. Kupangidwa mu 1930 kumayenera kugwiritsa ntchito pepala ndi zamkati, duptx matondo amachokera kuzungulira 22% crus ndi austetectic: microstructuctuctution yomwe imapulumutsa katundu.
Poyerekeza ndi mitundu ya mpweya 304/316 austetitic osapanga dzimbiri, banja la maulendo a Dutrax nthawi zambiri limakhala ndi mphamvu ndipo limapereka mphamvu yolimba pokana. Kuchulukitsa chromium zomwe zili m'mapewa osapanga dzimbiri zimawonjezera kukana kwawo kutukuka. Komabe, kutsutsana kokwanira Izi zimatha kugwiritsidwa ntchito kufotokoza momwe kusiyana pakati pa S31803 ndi S32205 idapangidwa ndipo kaya ndi nkhani.
Kutsatira chitukuko cha zitsulo zosapanga dzimbiri, zomwe zimatchulidwa koyamba zidagwidwa ngati S31803. Komabe, angapo otsogolera anali kupanga kalasi iyi mpaka kumapeto kwa mawonekedwe ovomerezeka. Izi zidawonetsera chikhumbo chawo chokulitsa kugwirira ntchito kwa zitsulo, mothandizidwa ndi chitukuko cha ntchito yomwe idapangitsa kuti iyambike kuwongolera. Kuphatikiza apo, imalolanso kuchuluka kwa nayitrogeni kuti atengedwe, m'malo mongokhala ngati chinthu choyambira. Therefore, the highest performing duplex grade sought to maximise the levels of chromium (Cr), molybdenum (Mo) and nitrogen (N). Kusiyana pakati pa nduna za Duptux omwe akukumana ndi pansi pamlingo wotchulidwa, yemwe akumenya pamwambayo akhoza kukhala mfundo zingapo malinga ndi formula =% cr + 16% n.
Kuti musiyanitse chitsulo chosapanga dzimbiri lomwe limapangidwa kumapeto kwenikweni kwa mapangidwe, kutanthauzanso kutanthauza kwina kunayambitsidwa, dzina S3205. Duplex stainless steel made to the S32205 (F60) caption will fully meet the S31803 (F51) caption, whereas the reverse is not true. Chifukwa chake S32205 itha kukhala yotsimikizika ngati S31803.
| Giledi | Ni | Cr | C | P | N | Mn | Si | Mo | S |
| S31803 | 4.5-6.5 | 21.0-23.0 | Max 0.03 | Max 0.03 | 0.08-0.20 | Max 2.00 | Max 1.00 | 2.5-3.5 | Max 0.02 |
| S32205 | 4.5-6.5 | 22-23.0 | Max 0.03 | Max 0.03 | 0.14-0.20 | Max 2.00 | Max 1.00 | 3.0-3.5 | Max 0.02 |
Sakysteel samalani ndi chitsulo chosapanga dzimbiri monga mnzake wogawa wa sandvik. Timakhala ndi S32205 m'matumbo kuchokera 5/8 "mpaka 18" mulifupi ndi masheya athu ozungulira sanmac® 2205, omwe amawonjezera makina oyambira 'ku zinthu zina. Kuphatikiza apo, timakhalanso ndi malo osiyanasiyana a S32205 kuchokera ku nyumba yathu ya UK.
