321 Stainless simbi chubhu 304 304L 316 316L 310S 321 Ss chubhu chubhu isina musono simbi
Tsanangudzo
321 Stainless Steel is austenitic Stainless simbi yakagadzika netitanium.321 zvakare ine chromium pamwe nickel uye kuwedzera kune titanium, inopa yakagadziridzwa inter-granular corrosion resistance.321 mune isiri-magnetic w / yakafanana corrosion resistance kune mhando 304. Ichi chinyorwa chinoshandiswa kune welded michina isingagoni kuvharwa.Pamusoro pezvo, inoshandiswa kumidziyo inoshandiswa pakati pe800 ne1500°F.
321 inowanikwa muround bar, ndiro, pombi, sheet, tubing, coil uye pombi.Kune chero 321 Stainless simbi inodiwa ndapota fonera Michlin Metals.Kuti uwane rumwe ruzivo nezve izvi pamwe nemamwe Austenitic Stainless Steels tarisa vhidhiyo pane iyo musoro wenyaya pazasi:
321 simbi isina seamless simbi machubhu (GB3087-1999) ndeyemhando yepamusoro kabhoni yekugadzira simbi inopisa-yakakungurutswa uye inotonhora-inodhonzwa (yakakungurutswa) isina musono machubhu, ayo anoshandiswa kugadzira anopisa kupisa pombi, kufashaidza pombi dzemvura dzakasiyana-siyana dzakaderera uye dzepakati pressure boilers. uye mapaipi anopisa zvakanyanya, pombi dzehutsi hombe, pombi diki dzehutsi uye mapaipi ezvidhinha arch emaboilers e locomotive.
321 Stainless steel chubhu: Inonyanya kushandiswa mukugadzira kumanikidza kwakanyanya uye pamusoro pekumanikidzwa kwemhepo boiler pombi, etc. Iine high quality carbon structural simbi, alloy simbi uye Stainless heat inodzivirira simbi isina seamless simbi chubhu, boiler chubhu nepati pasi pekushisa kwakanyanya uye high pressure pombi uye inoshanda mukupisa tembiricha flue gasi uye chiutsi zvichaitika pasi pechiito cheoxidation uye corrosion, saka pombi yesimbi ine simba rakanyanya kuputika, yakakwira oxidation kuramba, Uye ine yakanaka kugadzikana kwesangano, hydraulic prop chubhu.
321 simbi isina tsvina machubhu anounzwa mumamiriro ekupisa kupisa.Uye zvakare, iyo microstructure, saizi yezviyo uye decarburization layer yeakapedzwa simbi machubhu inodiwa zvakare.Mapaipi esimbi asina musono ekuchera geological uye petroleum drilling control;Kuti uongorore dombo repasi pevhu, pasi pevhu, oiri, gasi rechisikigo uye zvicherwa zviwanikwa, kushandiswa kwekuchera Wells.
