Chitoliro cha Chitsulo cha ASTM A335 Aloy

ASTM A335 Alloy Steel Chitoliro Chopanda Chitoliro Chowonetsedwa

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, komanso ntchito zamafuta komwe madzi ndi mpweya zimatengera kutentha kwambiri komanso kupanikizika.

Chiyambi cha Zamalonda

Kukana mwamphamvu kuphulika pa kutentha kwakukulu ndi kupanikizika kwakukulu.

Itha kugwiritsidwa ntchito ngati Hydrogen sulfide Corrosion Services.

Kukana kusweka kwa hydrogen kuukira ndi embrittlement.

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.
