ASTM A312 TP347 yog dab tsi
ASTM A312 TP347 stainless hlau yeeb nkab yog aniobium-stabilized austenitic stainless hlau yeeb nkabtsim raucorrosion-tiv taus thiab siab- kev siv kub. Los ntawm kev ntxiv niobium (Nb), TP347 zoo tiv thaiv chromium carbide nag lossis daus, kom ntseeg tau tiaszoo heev tiv thaiv intergranular corrosion, tshwj xeeb tshaj yog tom qab vuam los yog ntev raug rau qhov kub siab.
Piv nrog rau cov qib pa xws li TP304 thiab TP316 stainless hlau kav, ASTM A312 TP347 muabtxhim kho thermal stability thiab oxidation kuj, ua rau nws zoo tagnrho rauThaum tshav kub kub exchangers, refinery piping systems, thiab chemical processing equipment. Raws li ib tug txhim khu kev qha ASTM A312 TP347 yeeb nkab tsum, peb muajpuv -size seamless thiab welded kav, ua raws liASME SA312 tus qauv, kom ntseeg tau zoo ib yam thiab thoob ntiaj teb kev xa khoom.
