ASTM A335 P92 (ASME SA335 P92) ipombi yesimbi yeferritic alloy isina musono yakagadzirirwa kushandiswa pakupisa kwakanyanya.Chinzvimbo cheUNS chinonzi K92460.
P92 isimbi yesimbi inodzivirira kupisa ine chromium martensitic ine 8.50–9.50% chromium uye yakabatanidzwa neMo, W, V, uye Nb, iyo inopa simba rakanaka rekukwira kwekupisa, kuramba oxidation, uye kuramba kupisa kuneta.
Inoshandiswa zvakanyanya mumitsetse mikuru yemhepo inopfuta, mitsetse yemhepo inopfuta, machubhu ekupisa uye ekudziisa emabhaira emagetsi anopfuta zvakanyanya uye anopisa zvakanyanya, pamwe chete nemapombi ekupisa kwakanyanya, ane kumanikidzwa kwakanyanya uye zvikamu zvinochengetedza kumanikidzwa zvakanyanya munzvimbo dzemafuta nemafuta ekuchenesa.
Botop Steel inyanzvi uye yakavimbika mukutengesa mapaipi esimbi esimbi ye alloy muChina, inokwanisa kupa mapurojekiti ako nekukurumidza nemhando dzakasiyana dzemapaipi esimbi ye alloy, kusanganisiraP5 (K41545), P9 (K90941), P11 (K11597), P12 (K11562), P22 (K21590)uyeP91 (K90901).
Zvigadzirwa zvedu zvine hunhu hwakavimbika, zvine mutengo unokwikwidzana, uye zvinotsigira kuongororwa kwevamwe.
