Hom 347 (UNS S34700) hauv Coiled tubing
Kev piav qhia
347 stainless hlau coiled tubing
Hom 347 yog niobium stabilized chromium nickel austenitic stainless hlau nrog corrosion kuj zoo ib yam li 304/304L.Qib no feem ntau yog siv nyob rau hauv qhov kub ntawm 800-1500˚F qhov chaw uas nws ruaj khov tiv thaiv chromium carbide nag lossis daus los ntawm kev ntxiv niobium, uas ua rau nag lossis daus ntawm niobium carbide.Hom 347 muaj qhov zoo heev intergranular corrosion kuj tom qab raug rau qhov kub thiab txias, thiab qib no tiv taus oxidation mus txog 1500˚F thiab muaj ntau dua creep thiab kev nyuaj siab rupture zog tshaj 304/304L.Nws kuj tseem muaj qhov kub thiab txias toughness zoo thiab tsis yog-magnetic nyob rau hauv annealed mob.
