ASTM A312 TP321H Stainless Hlau Pickeld thiab Annealed Yeeb Nkab

ASTM A312 TP321H stainless hlau pickled thiab annealed yeeb nkab yog ib tug siab -kev ua tau zoo austenitic stainless hlau raj engineered rau siab - kub thiab siab - siab daim ntawv thov. Los ntawm kev koom ua ke tswj cov ntsiab lus ntawm carbon (0.04–0.10%) thiab titanium (70 × 0.0%) zoo dua, los yog ntau dua. tiv thaiv intergranular corrosion, yog li txhim kho creep kuj thiab cov qauv kev ruaj ntseg. Piv nrog rau tus qauv TP321, qib H- muaj cov ntsiab lus nruj dua cov pa roj carbon monoxide (tsuas yog 0.04% max) kom ntseeg tau tias muaj zog nkag tau zoo dua thiab siab dua -kub endurance.

​

Peb muabASTM A312 TP321H stainless hlau pickled thiab annealed kavyog tsim los siv kub dov lossis txias txheej txheem, ua raws li qhov tseem ceeb "pickled thiab annealed" (ci annealed) nto kho. Pickling tshem tawm cov oxides saum npoo thiab cov nplai uas tsim los ntawm kev kho cua sov, thaum annealing (feem ntau ua ntawm 1000-1100 degree) refines microstructure, optimizes grain ciam teb, thiab xyuas kom huv si, corrosion-resistant nto.Cov kav dej no tau siv dav hauv cov fais fab nroj tsuag boilers, superheaters, siab -kub txheej txheem piping systems, thiab lwm yam kev siv raug rau qhov xav tau ib puag ncig thermal.
