UNS S43900 Ferritic Stainless Hlau - Weld-Rov siab siab-Temp Alloy

Kev piav qhia

UNS S43900 yog titanium-stabilized ferritic stainless hlau, tsim los txhim kho intergranular corrosion kuj thiab weldability piv rau nws tsis yog -stabilized counterpart S43000. Nrog 17.0-19.0% chromium, nws xa cov corrosion kuj zoo nyob rau hauv atmospheric thiab tshuaj lom neeg ib puag ncig, thaum nws cov qauv ferritic ua kom cov khoom sib nqus. Qhov sib ntxiv ntawm 0.10-0.30% titanium tiv thaiv chromium carbide nag lossis daus thaum lub sijhawm vuam thiab siab - qhov kub thiab txias, tshem tawm qhov xav tau tom qab- vuam kev kho cua sov hauv ntau daim ntawv thov. Tsis zoo li S43000, S43900 muaj kev txhim kho weldability thiab siab - kub stability, ua rau nws haum rau welded Cheebtsam nyob rau hauv high-kub ib puag ncig. Nws yog tus nqi tsim nyog, muaj kev tsim tau zoo thiab ua haujlwm tau zoo, thiab yog qhov kev xaiv txhim khu kev qha rau cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob.
