Dab tsi ua rau 321 stainless hlau zoo tagnrho rau siab -kub cyclic ib puag ncig?

Titanium Stabilization:Qhov sib ntxiv ntawm titanium (Ti) khi cov pa roj carbon monoxide, tsim cov titanium carbides ruaj khov es tsis txhob chromium carbides ntawm cov ciam teb nplej, tiv thaiv rhiab heev thiab IGC thaum muaj kev kub ntxhov siab -.

 

Resistance rau Sensitization:Nyob rau hauv cov hlau austenitic ib txwm (xws li Hom 304), vuam lossis kub kub ua rau chromium carbide nag lossis daus, ua rau cov cheeb tsam tsis muaj zog tiv thaiv corrosion; 321's Ti ntxiv tshem tawm qhov teeb meem no.

 

Oxidation & Scaling Resistance:Nws tuav cov qauv kev ncaj ncees thiab tiv thaiv qhov degradation (scaling) thaum rov raug kub kub, txog li 850℃(1500℃F).

 

Zoo Mechanical Properties:Nws khaws zoo zog, toughness, thiab creep tsis kam ntawm qhov kub thiab txias, tseem ceeb heev rau cov khoom uas tau rov qab thermal stress.

 

Weldability zoo heev:Nws tuaj yeem welded yam tsis tas yuav tsum tau tshaj tawm -weld annealing, simplifying fabrication rau complex qhov chaw xws li tso pa system los yog cua kub exchanger raj.
