904L Stainless Hlau Yeeb Nkab

Kub Txias Nyias Phab Ntsa Seamless 904L Stainless Hlau Yeeb Nkab

904L stainless hlau yeeb nkab (00Cr20Ni25Mo4.5Cu) yog ib hom ntawm austenitic stainless hlau nrog corrosion kuj zoo dua. Nrog rau kev ntxiv ntawm 1.5% Cu, nws kuj muaj zoo heev corrosion kuj rau recuctive acids xws li sulfuric acid thiab phosphoric acid. Tsis tas li ntawd, nws muaj cov yam ntxwv qis hauv cov vuam siv.

Yam ntxwv

Nrog cov ntsiab lus qis ntawm cov roj (Max 0.020%) hauv 904L, yuav tsis muaj nag lossis daus hauv kev kho cua sov thiab kev siv welding. Qhov no tshem tawm txoj kev pheej hmoo ntawm kev sib txheeb ntawm corrosion uas tshwm sim tom qab kev kho cua sov thiab kev siv welding. Vim tias cov ntsiab lus ntawm 904L yog qhov qis qis tshaj (Max 0.020%), yog li ntawm qhov kev kho cua sov thiab kev siv welding, tsis muaj cov khoom carbides. Qhov no tshem tawm txoj kev pheej hmoo ntawm kev sib txheeb ntawm corrosion uas tshwm sim tom qab kev kho cua sov thiab kev siv welding. Vim muaj cov ntsiab lus ntawm chromium, npib tsib xees thiab molybdenum, nrog rau ntxiv ntawm lub Cu, 904L stainless hlau plab yuav kis tau txawm nyob rau hauv cov kev tshem tawm, piv txwv li nws tau passivated nyob rau hauv sulfuric acid thiab formic acid. Lub ntsiab nickel cov ntsiab lus ua rau tus nqi txheeb qis qis hauv lub xeev ua haujlwm. Hauv cov kua xoos sulfuric acid nrog concentration ntau ntawm 0 ~ 98%, kev kub hauj lwm ntawm 904L yuav tuaj txog 40 ℃. Hauv cov kua qaub phosphoric acid nrog cov concentration ntau ntawm 0 ~ 85%, nws txoj kev ua kom tsis muaj corrosion yog zoo heev. Nyob rau hauv industrial phosphoric acid tsim los ntawm ntub ua, impurity muaj ib tug muaj zog siv on corrosion tsis kam. Nyob rau hauv tag nrho cov phosphate, corrosion kuj ntawm 904L stainless hlau yeeb nkab zoo dua li zoo tib yam stainless hlau yeeb nkab. Nyob rau hauv lub oxidizing nitric acid, muab piv nrog cov phom heev heev uas tsis muaj cov molybdenum, nws muaj cov tshuaj tiv thaiv tsis tshua muaj. Kev siv ntawm 904L stainless hlau yeeb nkab hauv hydrochloric acid tsuas yog siv rau qhov qis concentration 1-2%. Tus corrosion kuj zoo ntawm 904L stainless hlau yeeb nkab hauv no concentration ntau yog zoo dua qhov uas cov pa tsw qab pa. Lub 904L stainless hlau kav muaj high point tiv thaiv corrosion. Hauv cov kua tshuaj chloride, nws txoj hauv kev muaj peev xwm ua kom tsis muaj zog ntawm cov kabmob crevice kuj zoo. Cov ntsiab nickel cov ntsiab lus ntawm 904L stainless hlau yeeb nkab thiaj ua rau tus nqi txhim khu ntawm cov qhov dej thiab cov kauj voj. Thaum lub ntsuas kub siab tshaj 60 ℃, qhov muaj zog austenitic stainless hlau yuav ua rau muaj kev ntxhov siab ntxhov plawv hauv cov chloride nplua nuj ib puag ncig. Qhov no hom rhiab heev yuav raug txo los ntawm kev nce cov ntsiab ntawm cov xim nickel ntawm stainless hlau. Vim yog lub ntsiab nickel cov ntsiab lus, 904L stainless hlau yeeb nkab muaj siab ua kom muaj kev ntxhov siab ntxhov plawv hauv cov kua chloride, kua concentrated hydroxide thiab hydrogen sulfide nplua nuj qhov chaw.

AL-904L yog ib hom qee hlau alloyed austenitic stainless hlau nrog tsawg cov ntsiab lus. Nws muaj corrosion kuj zoo dua tshaj 316L thiab 317L. Nyob rau tib lub sij hawm, nws suav tias yog ob qho tib si tus nqi thiab qhov sib piv ntawm kev ua tau zoo rau tus nqi yog siab heev. Rau qhov sib ntxiv ntawm 1.5% tooj liab, nws muaj kev txhim kho corrosion zoo rau kev txo cov acids xws li sulfuric acid thiab phosphoric acid.
