SS 309S / SS 309H Waya

SS 309S Chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri cha austenitic chomwe chimagwiritsidwa ntchito kukana kwabwino kwambiri kwa okosijeni, kutentha kwambiri, mphamvu, komanso kukana kukwawa. Nickel yotsika ya Stainless Steel 309, poyerekeza ndi Stainless Steel 310, imawonjezera kukana kwake kuukira kwa hydrogen sulfide (H2S) pakutentha kwambiri. Ndi yolimba komanso yodumphira ndipo imatha kupangidwa mosavuta ndikupangidwa ndi makina. SS 309S ndiye mtundu wa carbon wocheperako, ndipo umalimbikitsidwa kuti ugwiritse ntchito pomwe tcheru ndi dzimbiri zotsatizana ndi kutentha kwapang'onopang'ono pakuzimitsa zitha kukhala zovuta. Stainless Steel 309S imagwiritsidwa ntchito chifukwa cha kutentha kwake kwa okosijeni komanso kukana kuukira kwa H2S. 309S Stainless Steels imatha kupangidwa, kusindikizidwa ndikukokedwa mosavuta. In-process annealing nthawi zambiri imafunika kuonjezera ductility ndi kuchepetsa kuuma.
