Stainless Simbi – Giredhi 253MA (UNS S30815)

253MA igiredhi rinobatanidza yakanakisa sevhisi zvivakwa pakupisa kwakanyanya nekureruka kwekugadzira. Inopikisa oxidation patembiricha inosvika 1150 ° C uye inogona kupa basa repamusoro kune Giredhi 310 mucarbon, nitrogen nesarufa ine mhepo.

Rimwe zita remuridzi rinofukidza giredhi iri 2111HTR.

253MA ine nickel yakaderera, iyo inopa mukana wekuderedza sulphide atmospheres kana ichienzaniswa nepamusoro nickel alloys uye kuGrade 310. Kuiswa kwesilicon, nitrogen uye cerium zviri mukati kunopa simbi yakanaka oxide kugadzikana, kusimba kwekushisa kwepamusoro uye zvakanakisa. kuramba kune sigma phase precipitation.

Iyo austenitic chimiro chinopa iyi giredhi kusimba kwakanyanya, kunyangwe pasi kusvika kune cryogenic tembiricha.

Key Properties

Izvi zvivakwa zvakataurirwa chigadzirwa chakatenderedzwa (plate, sheet uye coil) seGiredhi S30815 muASTM A240/A240M. Zvakafanana asi zvisingaite zvakafanana zvivakwa zvinotsanangurwa kune zvimwe zvigadzirwa senge pombi uye bhara mune yavo yakatarwa.
