Qib 439 Stainless Hlau

Kev piav qhia

Qib 439 yog titanium-stabilized ferritic stainless hlau, tsim los txhim kho intergranular corrosion kuj thiab weldability piv rau Qib 430. Nws muaj 17.0-19.0% chromium, muab zoo corrosion kuj nyob rau hauv atmospheric thiab me me tshuaj ib puag ncig, thiab yog sib nqus. Qhov sib ntxiv ntawm titanium (0.10-}0.30%) tiv thaiv chromium carbide nag lossis daus thaum lub sij hawm vuam thiab siab -kub raug, tshem tawm qhov xav tau tom qab-weld kev kho cua sov nyob rau hauv ntau daim ntawv thov. 439 muaj zoo formability, weldability, thiab machinability. Nws yog ib qho txiaj ntsig zoo rau cov qib austenitic rau cov ntawv thov uas yuav tsum tau muaj kev txhim kho corrosion thiab weldability zoo . 439 yog siv dav hauv cov tsheb siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom lag luam uas cov qauv welded muaj ntau thiab intergranular corrosion yog ib qho kev txhawj xeeb.
