321 Stainless Hlau Tube 304 304L 316 316L 310S 321 Ss Tube Seamless Stainless hlau
Kev piav qhia
321 Stainless Hlau yog austenitic stainless hlau uas ruaj khov nrog titanium.321 kuj tseem muaj chromium nrog rau npib tsib xee thiab ntxiv rau titanium, muab kev txhim kho inter-granular corrosion kuj.321 nyob rau hauv non-magnetic w / zoo corrosion kuj rau hom 304. Cov khoom siv no yog siv rau cov khoom siv welded uas tsis tuaj yeem annealed.Tsis tas li ntawd, nws tau siv rau cov khoom siv uas ua haujlwm ntawm 800 thiab 1500 ° F.
321 muaj nyob rau hauv round bar, phaj, yeeb nkab, ntawv, tubing, coil thiab yeeb nkab.Rau ib qho 321 stainless hlau xav tau thov hu rau Michlin Hlau.Yog xav paub ntxiv txog qhov no thiab lwm yam Austenitic Stainless Steels mus saib ib daim vis dis aus ntawm cov ncauj lus hauv qab no:
321 stainless hlau seamless steel raj (GB3087-1999) yog cov zoo carbon steel hlau kub dov thiab txias-draw (dov) seamless steel hlab, uas yog siv rau kev tsim superheated chav kav, boiling dej kav ntawm ntau yam tsawg thiab nruab nrab siab boilers thiab superheated chav kav, cov pa luam yeeb loj, cov kav dej me me thiab cov kav dej ntawm cov kav dej ntawm cov kav dej boilers.
321 stainless hlau raj: Feem ntau yog siv nyob rau hauv kev tsim cov kev kub siab thiab tshaj siab chav boiler kav, thiab lwm yam. Nrog zoo carbon structural steel, hlau alloy thiab stainless kub resistant steel seamless steel raj, lub boiler raj los ntawm tog nyob rau hauv siab kub thiab Kev kub siab cov yeeb nkab thiab ua haujlwm nyob rau hauv qhov kub thiab txias flue roj thiab chav yuav tshwm sim nyob rau hauv qhov kev txiav txim ntawm oxidation thiab corrosion, yog li cov yeeb nkab steel nrog siab rupture lub zog, siab oxidation kuj, Thiab muaj lub koom haum zoo stability, hydraulic prop raj.
321 stainless hlau raj tau xa hauv kev kho cua sov.Tsis tas li ntawd, lub microstructure, grain loj thiab decarburization txheej ntawm cov hlau tiav lawm kuj yuav tsum tau.Seamless steel kav rau geological drilling thiab petroleum drilling tswj;Txhawm rau txhawm rau tshawb xyuas cov qauv pob zeb hauv av, dej hauv av, roj, cov khoom siv hluav taws xob thiab cov pob zeb hauv av, kev siv cov drilling Wells.
