Mamiriro epamusoro: pamusoro pemvura inotonhorera; kupukuta kwemuchina; kupenya kwakajeka
Kurapa kwekupedzisira: PE (muromo wakatsetseka), BE (Bevel)
Kurongedza: bhegi rakarukwa rakaunganidzwa / bhokisi replywood / kurongedza bhokisi rehuni rekutumira kunze
Mashoko: Pombi yesimbi isina ngura isingawanzoitiki inogona kugadziriswa zvichienderana nezvinodiwa nemutengi
253MA (UNS S30815) isimbi isingatsvi inopisa inodzivirirwa nekupisa yakagadzirirwa kushandiswa inoda simba rakawanda uye inodzivirira ngura zvakanaka. Tembiricha yayo yekushanda ndeye 850~1100 °C.
Kuumbwa kwemakemikari e253MA kwakaringana, izvo zvinoita kuti simbi ive nekushanda kwakakodzera kwakakwana muhurefu hwe850°C-1100°C, kuramba kuoxidation kwakanyanya, kupisa kuoxidation kusvika 1150°C, uye kuramba kuoxidation kwakanyanya. Kugona uye simba rekupwanyika kwe creep; kuramba kwakanaka ku ngura uye kuramba kuoxidation kwe brush mu gaseous media zhinji; simba guru re goho uye simba rekusunga pakupisa kwakanyanya; kugona kuumbwa zvakanaka uye kusvetwa, uye kukwanisa michina kwakakwana.
Pamusoro pezvinhu zvinosanganisa chromium nenickel, simbi isingatsvedzeri ye253MA inewo simbi shoma dzepasi dzisingatsvedzeri, nokudaro zvichivandudza zvakanyanya kugona kwayo kurwisa mabhakitiriya. Nitrogen inowedzerwa kuti ivandudze hunhu hwesimbi iyi uye kuti simbi iyi ive austenite zvachose. Kunyangwe zviri mukati mechromium nenickel zvakaderera, simbi dzisinatsvedzi dzakadaro muzviitiko zvakawanda dzine hunhu hwakafanana nehwesimbi dzine alloy dzakanyatsogadzirwa uye nickel base alloys.
