1.309s kalasi yachitsulo chosapanga dzimbiri
mtundu wofananira ku China ndi 06Cr23Ni13;Amercia Standard S30908, AISI, ASTM;JIS G4305 muyezo sus;Muyezo waku Europe 1.4833.
309s ili ndi chitsulo chosapanga dzimbiri chopanda sulfure, chomwe chimagwiritsidwa ntchito podula kwambiri komanso nthawi zowala / zoyera.
309s ndi mitundu yotsika ya kaboni ya 309 zitsulo zosapanga dzimbiri, kuwotcherera kumayikidwa pamwambowu.Mpweya wochepa wa carbon umapangidwa kumalo okhudzidwa ndi kutentha pafupi ndi weld mu mpweya wa carbide kuti ukhale wocheperako, ndipo zingapangitse mpweya wa carbide zosapanga dzimbiri intergranular dzimbiri m'madera ena (kuwotcherera kukokoloka).
2.309S Zapadera
Imatha kupirira kutentha mobwerezabwereza pansi pa 980 ℃, imakhala ndi mphamvu zapamwamba komanso kukana kwa okosijeni, kutentha kwambiri kwa carburizing.
