Hlau / steel rods & tuav: Cov qauv, tshuab, kev tsim kho, thiab kev siv engineering.
2. Cov alloys no txawv li cas ntawm corrosion thiab siab -kub tsis kam?
Teb:
Hastelloy X & C276: Exceptional tiv thaiv oxidizing thiab txo qhov chaw, ua tau zoo txog 1,200℃F (650 degree).
Inconel 600, 601, 738LC, 939: Zoo heev oxidation thiab creep resistance mus txog 1,100-1,200℃nyob ntawm qib.
Incoloy 825: Ua rau muaj zog acids, dej hiav txwv, thiab kev ntxhov siab corrosion tawg mus txog 870 degree.
Aluminum alloys: Moderate corrosion resistance; typically not suitable for very high temperatures (>200℃rau feem ntau alloys).
Stainless hlau: Corrosion resistant mus txog ~ 870℃nyob ntawm qib.
Titanium alloys: Zoo heev corrosion kuj, ruaj khov mus txog 600 degree; txo oxidation tsis kam ntawm kub heev.
Carbon steel / hlau: Yooj yim rau xeb; txwv corrosion kuj tsis muaj txheej los yog alloying.
3. Cov khoom siv tshuab dab tsi tuaj yeem xav tau los ntawm cov ntaub ntawv no?
Teb:
Hastelloy X & C276: Tensile zog ~ 450–{2}} MPa; zoo heev creep, qaug zog, thiab ductility.
Inconel 738LC: Tensile zog ~ 1,200-1,400 MPa; tsim los rau siab -kub creep resistance.
Inconel 600, 601, 939: Tensile zog ~ 580-1,240 MPa nyob ntawm qib; zoo qaug zog thiab siab -temp kev ua haujlwm.
Incoloy 825: Tensile ~ 515-690 MPa; zoo heev corrosion kuj nrog nruab nrab lub zog.
Aluminium alloys: Tensile ~ 200-550 MPa; lub teeb, nruab nrab qaug zog kuj.
Stainless hlau: Tensile ~ 500-1,000 MPa nyob ntawm qib; zoo heev toughness thiab ductility.
Titanium alloys: Tensile ~ 900-1,400 MPa; lub zog zoo heev - rau - qhov hnyav piv.
Carbon steel: Tensile ~ 400-800 MPa; siab zog tab sis txwv corrosion kuj.
4. Puas yog cov pas nrig thiab cov pas tuav tau weldable thiab machinable?
Teb:
Hastelloy & Inconel: Weldable nrog cov txheej txheem tshwj xeeb; machinable nrog cov cuab yeej ntse thiab qeeb qeeb vim kev ua haujlwm hardening.
Incoloy: Weldable siv tus qauv nickel-alloy txoj kev; nruab nrab machinability.
Aluminium: Zoo weldability thiab machinability.
Stainless hlau: Weldable nrog cov txheej txheem kom raug; machinable, tej zaum yuav xav tau tus nqi pub qeeb dua rau cov qib nyuaj.
Titanium: Weldable nrog inert roj shielding; machining yuav tsum tau qis ceev thiab coolant.
Carbon steel: Yooj yim weldable thiab machinable.
5. Cov pas nrig thiab cov pas tuav yuav tsum khaws thiab tuav li cas?
Teb:
Khaws rau hauv qhov chaw qhuav, huv si kom tsis txhob muaj kab mob oxidation.
Ua tib zoo tuav kom tsis txhob muaj cov hniav, khawb, lossis deformation uas tuaj yeem cuam tshuam rau qaug zog lossis corrosion kuj.
Rau lub hnub nyoog -hardenable los yog siab- kub alloys (Inconel 738LC, X-750, thiab lwm yam), zam lub sij hawm ntev raug rau kub kub ua ntej siv.
Khaws cov txheej tiv thaiv los yog ntim kom zoo kom txog thaum npaj rau kev teeb tsa.
Tsis txhob sib cuag nrog cov kua qaub lossis cov tshuaj chlorides tshwj tsis yog cov khoom tsim los rau nws.
