2205 Duplex Stainless Steel Tubes. Simbi inoshandiswa zvakanyanya inosanganisa simba rakawanda uye kuramba ngura muma organic acid akasiyana-siyana, anorganic acids, aggressive cooling waters uye hydrous H2 S/NaCl mixtures. Nemusanganiswa wakaenzana we austenite ne ferrite, zvinopa simba rekugadzira ne30% uye simba rekusunga rakakwira zvishoma pane austenitics ine nitrogen yakafanana. Kuramba kwakanyanya ngura uye kunyanya ngura yegomba nepaburi. Kuramba kwavo kuputika kwe stress-corrosion muma neutral chloride kuri nani pane kwema austenites. Munzvimbo dzine chloride acidic yakawanda kana ine sour iri pakati nepakati uko hydrogen kana sulphide stress cracking iri nyore, austenitics yakakwira inofanirwawo kufungwa nezvayo. Impact values ​​​​yakakwira uye tembiricha yekuchinja kwezvinhu zve base inosiyana-siyana - 50°C. Zvisinei, chiyero uye kurongeka kwe ferrite muma welds uye base materials zvinogona kukanganisa zvakanyanya kuomarara pa subzero tembiricha. Kusangana netembiricha iri pakati nepakati uye yakanyanya kutonhora uye kutonhora kushoma kunogona kukonzera embrittleness.
