ASTM A213 T12(ASME SA213 T12) isimbi yakaderera-alloy isina musono pombi yakagadzirirwa basa repamusoro-tembiricha.
Yayo yekutanga alloying zvinhu ndeye 0.80-1.25% chromium uye 0.44-0.65% molybdenum, iyo inoisa iyo chromium-molybdenum alloy simbi. Iyo inoshandiswa zvakanyanya munzvimbo dzepamusoro-tembiricha uye yakakwirira-kudzvanywa nharaunda senge boilers, superheaters, uye kupisa kunopisa.
T12 pombi ine simba shoma rekuita 415 MPa uye simba regoho shoma re220 MPa.
Mazita eUNS egiredhi iri K11562.
Botop Steel inyanzvi uye yakavimbika alloy simbi pombi stockist uye mutengesi muChina, inokwanisa kukurumidza kugovera mapurojekiti ako nemagiredhi akasiyana emapombi esimbi alloy, kusanganisira.T5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590),uyeT91 (K90901).
