Vim li cas rau corrosion ntawm stainless hlau welded yeeb nkab

Ib co stainless hlau welded yeeb nkab tom qab ua tiav ntau lawm, tom qab ib lub sijhawm muaj corrosion nyob rau saum npoo, thiab txawm tawg, vim li cas thiaj tau tawg, vim li cas?

Vim tias hauv cov txheej txheem ntau lawm ntawm cov kav dej welded, ib kauj ruam tseem ceeb heev yog tsis quav ntsej, uas yog, 'annealing '. In the process of steel smelting and production, we will adjust the element formula to make the steel achieve the characteristics we need, such as Cr, Cr, Ni, N, Nb, Ti, Mn, Mo, Si and other metal elements. Qhov kev ua tau peb yuav tsum tau txhim kho yog qhov muaj feem cuam corrosion tsis kam ntawm cov hlau, uas yog qhov peb hu ua stainless hlau. Cov corrosion tsis kam ntawm stainless hlau los ntawm ib qho keeb kwm muaj nyob hauv cov qauv - cr. Thaum cov ntsiab lus ntawm Taipa mus txog lub ncov, cov corrosion tsis kam ntawm cov hlau yuav muaj kev txhim kho zoo heev. Cov ntsiab lus croral crown ntawm stainless hlau yuav tsum ncav cuag tsawg kawg 10,5%.

Hom Corrosion: Qib intergranular, kev nyuaj siab corrosion

Intergranular corrosion, nws qhov tshwm sim ntawm intergranular corrosion hauv cov steel ua kom haum rau cov khoom siv roj welded, thiab qhov kawg ua rau muaj kev sib tshuam.

Kev ntxhov siab corrosion los ntawm cov tshuaj tiv thaiv kev tsim tawm thaum tus txheej txheem steel yog deformed los ntawm kev sib sau theem, thiab yuav nyob rau hauv cov theem welded tom qab vuam. Yog tias tsis tshem tawm nyob rau hauv lub sijhawm, lub hardness ntawm welded yeeb nkab yuav ua tshwj xeeb, thiab nws nyuaj rau kev ua tiav kev ua haujlwm tom ntej.

Hauv kev pom ntawm ob qho teeb meem muaj teeb meem zoo, yuav ua li cas peb cov cuab yeej ua tau cov tshuaj kho?

Cov nta ntawm lub tshuab ci ci ci ntawm Hangao Technology Company:

1, zoo qoob loo, cov qauv sib xyaw ua ke steel thiab muaj pes tsawg leeg.

2, tshem tawm kev ntxhov siab sab hauv ntawm cov hlau thiab tiv thaiv deformation thiab kev tawg.

3, txo qhov tawv ntawm cov hlau, txhim kho kom muaj zog, txhim kho kom yooj yim los pab txhawb ntxiv.

Tsib cov ncauj lus kom ntxaws nta ntawm ci annealing khoom:

1, Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

2, cov roj hauv cov dej hluav taws xob yuav ua rau cov roj cua sov dej kom yaj, thiab cov pa dej dej uas muaj cov dej ntws tau txuas nrog cov yeeb nkab ntawm cov yeeb nkab stainless thiab oxidized.

3, Cov roj siab hauv lub cev rauv taws, txhawm rau zam cov roj sab nraud mus rau hauv lub qhov cub hluav taws xob, lub siab nyob rau hauv lub cub tawg yuav tsum loj dua sab nraum siab.

4, annealing kev tswj kub, seb puas yuav ua tiav cov kev kub zoo tshaj plaws ntawm cov hlau yeeb nkab.

5, Cov roj uas yuav tsum muaj nyob hauv cov txheej txheem anealing, stainless hlau yeeb nkab roj yog qhov zoo tshaj plaws, wireless ze rau cov pa oxygen, dej roj. Vim tias roj yog thawj qhov laj thawj rau kev cuam tshuam qhov zoo ntawm cov kav dej stainless hlau.
