Ingxubevange 20 Stainless Steel

I-alloy 20 (UNS N08020) iyingxubevange ye-austenitic, i-nickel-iron-chromium esekelwe ku-super alloy enezengezo ze-Copper ne-Molybdenum ehlinzeka ngokumelana nezindawo ezinobutha, i-pitting, kanye nokugqwala kwe-crevice. Iphinde izinze ne-Columbium ukuze kuncishiswe imvula ye-carbide ngesikhathi sokushisela. I-alloy 20 ibonakala ingena phakathi kokubili izigaba ze-stainless ne-nickel njengoba iqukethe izici zakho zombili. Yakhelwe ukumelana okuphezulu nokuhlaselwa kwe-asidi futhi ikhombisa ukumelana okuphakeme nokuqhekeka kwe-stress-corrosion ebilisa i-sulfuric acid engama-20% kuya ku-40%, futhi inokumelana nokugqwala okujwayelekile okuhle kakhulu kwe-sulfuric acid kanye nokuqhekeka kokugqwala kwe-chloride. I-alloy 20 inezici ezinhle zomshini kuwo womabili amazinga okushisa azungezile naphakeme, afinyelela cishe ku-930°F (500°C) futhi yenziwa kalula ngezinqubo ezivamile zezimboni.

Izici

• Ukugqwala okuphezulu, ukugoba kanye nokumelana nokuqhekeka
• Iqukethe i-Niobium yokuqinisa ngokumelene nokuzwela kanye nomphumela wokugqwala kwe-intergranular
• Izakhiwo ezinhle kakhulu zemishini kanye nokwenziwa
• Imvula encane ye-carbide ngesikhathi sokushisela

Izinhlelo zokusebenza
Ngenxa yokumelana nokugqwala okukhulu, i-Alloy 20 isetshenziswa ekucubunguleni amakhemikhali, ekukhiqizeni ukudla, kwezemithi, ekukhiqizeni amandla nasekusetshenzisweni kwepulasitiki. Amavalvu, amaphampu kanye nezinhlelo zokucindezela ezinye zezingxenye ezidume kakhulu lapho kusetshenziswa i-Alloy 20.
