Kufotokozera Kwachidule:
ASTM A335 nthawi zambiri imatchedwa chrome moly pipe chifukwa cha mankhwala omwe ali ndi Molybdenum (Mo) ndi Chromium (Cr).Molybdenum imawonjezera mphamvu yachitsulo ndipo Chromium (kapena chrome) ndiye chinthu chofunikira kwambiri chachitsulo chosapanga dzimbiri.Chitoliro chachitsulo cha chrome moly alloy chimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'mafakitale amagetsi, malo oyeretsera, malo opangira mafuta amafuta, ndi ntchito zamafuta komwe madzi ndi mpweya zimatengera kutentha kwambiri komanso kupanikizika.
Lingani udindo wonse kukwaniritsa zofuna za ogula athu;kupeza zopititsa patsogolo mosalekeza polimbikitsa kupititsa patsogolo makasitomala athu;Kukula kukhala omaliza ogwirizana okhazikika amakasitomala ndikukulitsa zokonda za ogula a ASTM A335 Alloy Seamless Pipe Low Alloy Steel Seamless Alloy Steel Tube, Tikuyembekezera kulandira zofunsa zanu mwachangu ndipo tikuyembekeza kukhala ndi mwayi wogwira ntchitoyo limodzi. ndi inu m'tsogolomu.Takulandilani kuti muwonetsetse ku bungwe lathu.

Kukana mwamphamvu kuphulika pa kutentha kwakukulu ndi kupanikizika kwakukulu.
Itha kugwiritsidwa ntchito ngati Hydrogen sulfide Corrosion Services.
Kukana kusweka kuchokera ku kuwukira kwa haidrojeni ndi kuphulika.
Kulimbana ndi kutentha kwa dzimbiri kwa sulfide.
Itha kugwiritsidwa ntchito pa Mapulogalamu a NACE pomwe malo owawa ali pansi pa kutentha kwambiri komanso kupanikizika.
Itha kugwiritsidwa ntchito mu NACE-MRO 175 Sour Service.
Oyenera ntchito zokwawa rupture.
Imatha kupirira kutentha kwambiri ndi elasticity yotsika kwambiri.
Mitundu yazitsulo za alloy zomwe zimakutidwa ndi ASTM A335 - ASME SA335 zidapangidwa ndi prefix "P", kuyambira P5 mpaka P92.Magiredi P11/P22 ndi P91/92 nthawi zambiri amapezeka m'malo opangira magetsi, pomwe giredi P5 ndi P9 ndizofala kwambiri pamakampani opanga mafuta.Magiredi P9, P91 ali, pamndandanda, okwera mtengo kwambiri
