Khoom Description
Peb Qhov Zoo
1. Kev kub siab oxidation tsis kam
- Peb 321 Stainless Seamless Steel Exhaust Tubing yog ua los ntawm siab - zoo 321 stainless hlau, tuav corrosion kuj thiab cov qauv kev ncaj ncees ntawm qhov kub thiab txias mus txog 925 degree.
- Tubing nto yog pickled thiab passivated los txhim kho nws siab -kub corrosion kuj. Nws kuj tau dhau los ua qhov siab - qhov ntsuas kub ntawm oxidation thiab kev ntsuas kev ua haujlwm ntawm lub tshuab kom paub meej ntev - lub sij hawm ua haujlwm nyob rau hauv tsheb, aerospace, thiab cov tshuab tso pa tawm.
2. Muaj zog corrosion kuj
- Peb 321 Stainless Seamless Steel Exhaust Tubing yog ib lub raj seamless tsim los ntawm cov txheej txheem kos duab txias. Piv nrog rau cov kav dej welded, qhov tsim seamless tshem tawm cov ntsiab lus tsis muaj zog thiab tiv thaiv corrosion.
- Peb cov tubing tau dhau los ntawm kev kuaj xyuas kev sib tsoo thiab kev kuaj xyuas passivation kom ntseeg tau tias muaj kev tiv thaiv corrosion zoo heev, muaj peev xwm tiv taus qhov kub thiab txias, noo noo, thiab oxidizing gases, ua rau nws zoo tagnrho rau cov tshuab pa.
3. High Deg tiav
- Peb cov tubing undergoes pickling, passivation, thiab mechanical polishing, uas ua rau lub siab smoothness nrog ib tug nto roughness ntawm 0.8μm thiab 0.4μm. Rau aerospace daim ntaub ntawv, peb muab polished nto nrog Ra tsawg dua los yog sib npaug rau 0.4μm.
- Cov tubing tau txais kev soj ntsuam nruj, nrog rau kev tshuaj xyuas qhov muag thiab kev ntsuas tam sim no, kom ntseeg tau tias cov tubing zoo raws li ASTM A213 cov qauv.
4. Zoo heev machinability
- 321 stainless hlau muaj machinability zoo heev thiab tuaj yeem txiav, khoov, lossis tsim rau hauv cov duab kev cai yam tsis muaj kev tawg lossis deformation.
- Cov tubing tau txais kev ntsuas kev ua tau zoo thiab kev sim khoov / flattening los xyuas kom meej lub zog tensile, tawm lub zog, thiab elongation yuav tsum tau ua.
thaj chaw siv
- Automotive Exhaust Systems: Manifolds, downpipes, catalytic converters, thiab mufflers rau tsheb, maus taus, thiab tsheb thauj khoom.
