A358 TP347 Stainless hlau yeeb nkab
A358 TP347 stainless hlau yeeb nkab yog lub siab carbon austenitic stainless hlau yeeb nkab, nrog rau cov khoom siv hluav taws xob zoo heev uas yog siv rau boiler, tshav kub exchanger, tsheb thiab dav hlau tso, cov khoom siv tshuaj lom neeg thiab lwm yam. Raws li qib siab dua los ntawm AISI 321H, intergranular corrosion. ntawm 347H yog ua tiav los ntawm kev siv niobium (Nb) ua lub zog ruaj khov kom ua kom qhov zoo tshaj plaws no. SS 347 muaj qhov zoo ntawm cov khoom siv vuam kev ua tau zoo, zoo heev tiv thaiv intergranular corrosion.

seamless, ncaj-seam welded, thiab hnyav hnyav ua haujlwm welded austenitic stainless hlau yeeb nkab npaj rau high-temperature thiab corrosive kev pab cuam.
TP347 S34709 stainless hlau yog austenitic stainless hlau uas muaj cov khoom ruaj khov. Cov alloys no yooj yim welded. Annealing yuav tsis tas yuav tsum tau tom qab vuam tshwj tsis yog xav tau kev ntxhov siab. 347 stainless hlau muaj kev tiv thaiv zoo heev rau oxidation thiab corrosion. Nrog rau siab creep zog, 347 stainless hlau ua hauj lwm zoo tshaj plaws mus txog 1600 degree F. Qhov sib ntxiv columbium ntxiv rau tantalum hauv 347 stainless hlau muab ib co yam ntxwv xav tau.
ASTM A358 ASME SA358 Stainless hlau EFW kav
Txheem Specification rau Hluav Taws Xob-Fusion-Welded Austenitic Chromium-Nickel Stainless Hlau Yeeb Nkab rau Kev Pabcuam Kub Kub thiab Kev Siv Dav Hlau
ASTM A358 Stainless hlau EFW kavspecification npog hluav taws xob-fusion-welded austenitic chromium-nickel stainless hlau yeeb nkab haum rau corrosive los yog high-temperature kev pab cuam, los yog ob qho tib si, los yog rau kev siv dav siv.
Qhov kev qhia tshwj xeeb no suav nrog cov qib ntawm cov hlau alloy thiab stainless hlau uas tau teev tseg hauv Table 1. Kev xaiv cov qib kom zoo thiab cov kev xav tau rau kev kho cua sov yuav tsum nyob ntawm qhov kev txiav txim siab ntawm tus neeg yuav khoom, nyob ntawm seb cov kev pabcuam yuav raug ntsib.
