DIN 1.4450 stainless hlau yog dab tsi?
German tus qauv steel qib 1.4550 yog sib npaug rau AISI 347 (los yog SS347) thiab UNS S34700. Nws yog niobium-stabilized austenitic stainless hlau paub txog nws zoo corrosion kuj thiab siab - kub lub zog, thiab tseem hu ua X6CrNiNb18-10 nyob rau hauv European qauv. Nws yog siv rau hauv daim ntawv thov uas yuav tsum tau tiv thaiv carbide nag lossis daus, xws li hauv tshuaj, aerospace, thiab zaub mov kev lag luam. Nws cov qib sib npaug suav nrog JIS SUS 347 thiab AFNOR Z6CNNb18-10.
Dab tsi yog qhov muaj pes tsawg leeg ntawm 1.4550 stainless hlau?
1.4550 stainless hlau (tseem hu ua AISI 347) yog ib qho stabilized austenitic stainless hlau, feem ntau muaj hlau (Fe), thiab muaj cov nyiaj chromium (Cr, 17-19%) thiab nickel (Ni, 9-12%). Nws ruaj khov los ntawm qhov sib ntxiv ntawm niobium (Nb) los tiv thaiv carbide nag lossis daus. Nws tuaj yeem ua tiav rau hauv ntau hom khoom siv, nrog rau cov phaj, coils, raj, tuav, thiab cov xov hlau, nrog rau cov tshuaj sib txawv.
1.4550 stianless steel tshuaj muaj pes tsawg leeg yog muab raws li % los ntawm huab hwm coj.

1.4550 stainless hlau (AISI 347) yog niobium-stabilized austenitic qib tsim los rau kev kub siab corrosion mus txog 870-925 degree. Nyob rau hauv sib piv, 1.4961 yog cov cua kub-tiv taus stainless hlau npaj rau huab cua kub ib puag ncig mus txog 1100-1150℃. 1.4550 feem ntau yog siv rau welded lug, tshav kub exchangers, thiab tshuaj ua cov cuab yeej, whereas 1.4961 yog ua hauj lwm nyob rau hauv turbine Cheebtsam, lub zog hluav taws xob siv nyob rau hauv lub sij hawm ntev ntawm qhov kub thiab txias. xav tau.
Ob leeg 1.4550 thiab 1.4541 yog stabilized austenitic stainless hlau, tab sis lawv siv cov ntsiab lus stabilizing sib txawv . 1.4550 (347) siv niobium (Nb) los txhim kho kev tiv thaiv rau intergranular corrosion tom qab vuam, thaum 1.4541 (321) (ua hauj lwm rau titan) txoj hauj lwm zoo rau titanium. 870℃. 1.4541 yog ntau dua Feem ntau xaiv rau lub tshuab tso hluav taws xob tsheb thiab kev siv hluav taws xob dav dav, qhov 1.4550 nyiam dua rau kev caij tsheb kauj vab hnyav dua thiab ua rau muaj kev kub ntxhov ntau dua.
1.4301 muaj 18-20% Cr thiab 8-10.5 % Ni, muab nws zoo heev tag nrho corrosion kuj, tab sis nws tsis ruaj khov tiv thaiv carbide nag lossis daus, yog li nws muaj feem cuam tshuam rau intergranular corrosion tom qab vuam. Los ntawm qhov sib txawv, 1.4550 yog niobium-stabilized thiab tshwj xeeb tsim los rau kev pabcuam kub siab txog 870 degree, tswj kev ua haujlwm zoo thaum caij tsheb kauj vab. Yog li ntawd, 1.4301 tau siv dav rau cov khoom siv ua zaub mov thiab kev tsim khoom siv dav dav, thaum 1.4550 raug xaiv rau cov hlab ntsha siab, cov khoom siv hluav taws xob, thiab cov kav dej kub uas zoo tshaj qhov weldability thiab thermal reliability yog qhov tseem ceeb.
Yog tias koj muaj qhov yuav tsum tau ua rau 347 1.4550 stainless hlau, peb txais tos koj xaj. GNEE muaj cov khoom muag loj ntawm cov khoom nrov rau koj xaiv. Nws tuaj yeem ua tiav rau hauv ntau yam khoom siv, nrog rau daim hlau, coils, raj, tuav, xov hlau, thiab lwm yam.
