12Cr1MoV pepa kila ʻōwili wela

12Cr1MoV kila poepoe i kiekie ae oxidation kū'ē a me ka thermal ikaika. ʻO ka palena creep o kēia kila kokoke loa i ka waiwai o ka ikaika hoʻomanawanui, a he kiʻekiʻe ka plasticity i ka hihia o ka ʻeha mau loa; maikaʻi ka hana a me ka weldability o ke kila, akā pono e hoʻomaʻamaʻa ʻia i ka 300 ° C ma mua o ka hoʻopili ʻana a me ka hoʻoluhi pilikia ma hope o ka hoʻopili ʻana. hana pū. He kila kila ia i hoʻohana nui ʻia i ke kaomi kiʻekiʻe, ka puʻe kiʻekiʻe kiʻekiʻe, subcritical power station boiler superheaters, poʻo a me nā ducts nui. Loaʻa iā ia ka ikaika wela kiʻekiʻe a me ke kūpaʻa oxidation ma 580 ° C, a ʻo ka pā kila 12Cr1MoV he ʻoi aku ka lōʻihi o ka plasticity. He mea maʻalahi ke kaʻina hana, a maikaʻi ka hana kuʻi ʻana, akā ʻoi aku ka maʻalahi i ka helu hoʻomaha maʻamau. ʻO ka hoʻohana lōʻihi ma 580 ° C e hana i ka pearlite spheroidization.
