Cov Qauv: ASME SA213 / SA213M Boilers, Ferritic thiab Austenitic Alloy Seamless Steel Tubes rau Superheaters thiab Kub Exchangers, ASTM SA312 / SA312M Seamless, Welded thiab Deep Processed Austenitic Stainless Tubes, ASTM A213 / A213 Superheated seamless steel yeeb nkab Kub exchangers thiab kub exchangers, ASTMA312 / A312 seamless, welded thiab sib sib zog nqus-ua austenitic stainless hlau kav.
Khoom npe 317L tseem hu ua (SUS317L, S31703, UNS S31726, 022Cr19Ni13Mo3, 1.4438)
Khoom specifications: sab nraud txoj kab uas hla 6mm ~ 762mm, phab ntsa thickness 1mm ~ 140mm. Ntev 4m ~ 12m, tuaj yeem kho.
Cov txheej txheem ntau lawm; Kub dov, kos duab txias, dov, xa khoom raws li txoj cai: kev kho cua sov, pickling.
317L stainless hlau yeeb nkab yog ib hom ntawm stainless hlau thiab belongs rau kub-resistant hlau. Vim nws cov ntsiab lus tsis tshua muaj carbon, nws kuj yog ultra-low carbon stainless hlau. Piv nrog cov pa chromium-nickel austenitic stainless hlau xws li 304 alloy, nws muaj zog tiv taus tshuaj corrosion. Tsis tas li ntawd, piv nrog cov pa stainless hlau, 317L alloy muaj ntau dua ductility, kev nyuaj siab corrosion, thiab siab tsis kam. Lub zog thiab kub tsis kam. Nws yog qib qis carbon lossis qib L, qib no muaj kev ua haujlwm tsis zoo thaum vuam thiab kho cua sov.
