Cov ntsiab lus ntawm stainless hlau vuam txheej txheem

Ob: txheej txheem vuam

Kev xaiv ntawm stainless hlau vuam cov ntaub ntawv yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "homogeneity".

1. Ferritic stainless hlau Yog tias cov txheej txheem vuam yog rhuab ntawm 430-480 ° C rau lub sijhawm ntev thiab txias maj mam, nws yooj yim heev los tsim 475 ° C brittleness, thiab impurities yuav ua lub luag haujlwm catalytic.Cov txheej txheem vuam pom zoo kom tsis tshua muaj tam sim no, vuam ceev, tsis muaj oscillation, thiab qis interlayer kub tswj thaum lub sij hawm multilayer vuam.Txhawm rau weld tuab workpieces, weld seam yuav tsum tau hammered kom txo qis kev ntxhov siab.

2. Martensitic stainless hlau tshav kub-cuam tshuam cheeb tsam embrittlement thiab vuam txias tawg yog xav tau kom tsis txhob ntau npaum li sai tau thaum vuam, feem ntau coj tus coj preheating ua ntej welding (150-300 ° C) thiab tom qab vuam kub kho (700-750 ° C) kev ntsuas, kev siv cov kab loj loj, yog tias tsim nyog, koj tuaj yeem xaiv cov khoom siv vuam austenitic.

3. Austenitic stainless hlau Qhov cuam tshuam ntawm kub tawg thiab intergranular corrosion yog qhov tseem ceeb rau kev vuam ntawm cov hlau tsis muaj steel, vim nws cov yam ntxwv ntawm lub cev, me me linear zog yuav tsum tau muab coj los siv rau vuam, cua txias, thiab kub interlayer tsawg. yuav tsum tau tswj thaum multilayer vuam.Siv zog kom muaj qhov zoo ntawm ferrite thaum vuam los tiv thaiv qhov tshwm sim ntawm thermal tawg.Hauv kev lag luam petrochemical xws li hydrogenation reactors thiab lwm yam khoom tshwj xeeb, tus naj npawb ntawm ferrites (FN) ntawm cov vuam tau hais meej meej, feem ntau xav tau 3-10.

4. Austria-hlau duplex stainless hlau muaj qhov tsis tshua muaj kev sib tsoo piv nrog austenitic hlau;Piv nrog cov hlau ferritic, tom qab vuam embrittlement yog tsawg, yog li nws muaj qhov zoo tshaj plaws weldability, tsis preheating los yog tom qab cua sov, thiab tsis muaj vuam tawg.Txawm li cas los xij, thaum cua sov ntawm qhov kub thiab txias, nws muaj kev nyiam rau cov qoob loo loj hlob, thiab lub zog me me yuav tsum tau siv thaum vuam.

5. Cov dej nag-hardened stainless hlau Vim lub siab hardness, tsis zoo toughness thiab plasticity ntawm hom hlau no, thiab loj welding residual kev nyuaj siab, nws yog ib qho yooj yim los tsim cov kab nrib pleb.Cov txheej txheem vuam zoo ib yam li martensitic stainless hlau tau pom zoo, tab sis qhov kub thiab txias yuav tsum tau nce ntxiv.

Nco tseg:Lub AWSA5.9 Standard for Stainless Steel Optical and Filler Wires thiab YB/T5092 Standard for Stainless Steel for Welding stipulate that the chemical analysis of melted specimens of together or stranded wire or filler wire yog tib qho kev sim uas xav tau rau kev faib tawm ntawm cov khoom no. daim ntawv.Ntawd yog, cov khoom siv kho tshuab thiab lwm yam kev sim, raws li cov neeg siv khoom xav tau.
Stainless hlau tes electrode GES series, tsab ntawv kawg B hauv cov khoom npe qhia lub tsho xiav, R qhia lub tsho liab, xws li GES-308R sawv cev rau lub tsho liab GES-308, GES-312B sawv cev rau lub tsho xiav ntawm daim tawv nqaij GES-312 .
