ASTM A213 ASME SA312 SS 347

347 birta aan dahsoon waa kolumbium / tantalum xasiloon austenitic chromium-nickel birta aan lahayn. Walaxdan waxa lagu dejiyay ka-hortagga samaynta chromium carbide marka lagu daro kolumbium iyo tantalum. Maadaama walxahan ay u leeyihiin xidhiidh ka xoog badan kaarboonka marka loo eego chromium, kolumbium-tantalum karbides waxay ku da'ayaan gudaha  badarka halkii ay ka samayn lahaayeen xuduudaha badarka. 347 waa in loo tixgeliyo codsiyada u baahan kuleyl kala go'a inta u dhaxaysa 800ºF (427ºC) iyo 1650ºF (899ºC) ama alxanka hoos yimaada xaaladaha ka hortagaya soo laabashada alxanka kadib. 347 waa non-magnetic.
