347 Birta Birta Ah
UNS S34700 (Fasalka 347)
347 birta aan birta lahayn, sidoo kale loo yaqaan UNS S34700 iyo Fasalka 347, waa bir austenitic ah oo ka samaysan .08% ugu badnaan kaarboon, 17% ilaa 19% chromium, 2% ugu badnaan manganese, 9% ilaa 13% nikkel, 1% ugu badnaan silicon , raadadka fosfooraska iyo baaruudka, 1% ugu yaraan ilaa 10% ugu badnaan columbium iyo tantalum oo leh dheelitirnaanta birta. Fasalka 347 ayaa faa'iido u leh adeegga heerkulka sare sababtoo ah sifooyinka farsamada ee wanaagsan; Waxa kale oo ay leedahay iska caabin aad u fiican oo ku saabsan daxalka intergranular ka dib soo-gaadhista heerkulka ee roobabka chromium carbide ee u dhexeeya 800 ° ilaa 1500 ° F. Waxay la mid tahay Fasalka 321 marka loo eego daxalka intergranular kaas oo lagu gaaro isticmaalka kolumbium sida walxaha xasilinta kor u qaad sifadan. Fasalka 347 laguma adkeyn karo daawaynta kulaylka, laakiin guryaha sare ayaa laga yaabaa in lagu helo hoos u dhac qabow.
