ASTM A213 T9, inozivikanwawo seASME SA213 T9, isimbi isina simba rakawandachubhu yesimbi isina musonoinoshandiswa kumaboiler, masuperheater, uye ma heat exchangers.
T9 imhando yechromium-molybdenum ine 8.00–10.00% chromium uye 0.90–1.10% molybdenum. Ine simba rekudhonza re415 MPa uye simba rekuburitsa re205 MPa. Nesimba rayo rakanaka rekupisa kwepamusoro, kuramba kuoxidation, uye kuramba kukambaira, T9 inoshanda zvakanaka mumamiriro ekushanda ane kupisa kwakanyanya uye kumanikidzwa kwakanyanya.
Semutengesi wemapaipi esimbi alloy uye mutengesi wezvinhu zvakawanda muChina,Simbi yeBotopinogona kukurumidza kupa mapaipi esimbi eT9 akasiyana-siyana kumapurojekiti ako, ane mhando yakavimbika uye mitengo inokwikwidzana.
Chigadzirwa chakapihwa kuASTM A213 chinofanira kutevedzera zvinodiwa neSpecial ASTM A1016, kusanganisira chero zvimwe zvinodiwa zvinoratidzwa muodha yekutenga.
