Mapaipi 254 amatha kupirira kupsinjika kwa makina opanga masewera olimbitsa thupi komanso aloy 254 osuma amagwira ntchito yopanikizika kwambiri komanso malo okhala.
Mantha ndi zida, zomwe zimagwiritsidwa ntchito polumikizana ndi mapaipi, mavesi, ndi mapampu m'matumbo. Ma flanges osuta 254 amapangidwa ndi woipa wa chromium, nickel, ndi molybdenum. Izi zimapangitsa kuti ziwopsezo izi zizikhala ndi mankhwala abwino kwambiri okhala ndi oxidation. Amapezeka mu kukula pakati pa 1 \ / 8 nb mpaka 24 NB. Ma flanges 254 ali ndi chromium yayikulu poyerekeza ndi zitsulo zina motero ndikukana zabwino. Masitepe 254 osuntha ma flanges ali ndi 10% ya chromium. Khodi lokhazikika la kalasi 254 limakhala khosi lalitali limakhala lokhazikika komanso kukhala ndi mphamvu yochepa ngakhale kutentha kumakhala kotalikirapo. Mahatchi 254 Omwe Amakhala Ndi Masitepe Omwe Mapangidwe ake amathandizira kuthana ndi kukana, mphamvu yayikulu, kupsinjika kwa chipongwe, kupindika. Chimodzi mwazinthu zoterezi ndi m'magulu a Martie Sthulfuuration, komwe kutentha kwachilengedwe kumakhala kwakukulu kuposa chitsulo cha 6Mo Flat Fringe ndichabwino. Izi ndizotheka chifukwa cha kuchuluka kwa nickel mu chiloloni, popanda kusintha kulikonse pamakina ake.
