Cov khoom lag luam
S355j2w n steel phiajYog qhov zoo tshaj plaws pom tau rau lawv cov khoom lag luam zoo nkauj, feem ntau yog vim tias lub alloy pab ua haujlwm rau kev ua haujlwm kom tiav rau hauv qhov kub thiab txias.
Yog tias kev xaiv alloy tsis yog lawm, nws tuaj yeem ua rau cov khoom lag luam tsis muaj. Yog li, s35555555555555555555555555555555555555555555555555555555555555555555555555555555ong yog qhov zoo tagnrho vim nws cov khoom siv neeg kho kom zoo thiab tshuaj lom neeg. Xws li cov phiaj yog tsis muaj cov phiaj hlav muaj ntau yam hauv kev thov hauv kev siv ntawv thov siv zoo li.
S355j2W + N yog cov qauv hlau uas tseem tiv taus huab cua. Nws yog tsim nrog ib txheej uas hu ua ib txheej thaiv uas yog tsim thaum lubS355j2w n steel phiajtuaj sib chwv nrog kev txo ib puag ncig.
Tsis tas li ntawd, cov phiaj xwm zoo li no tau muab cov khoom ua zoo tshaj plaws xws li {{free {{tiv taus, thiab crevice {1} {resistant; Nws tiv taus oxidation, chloride kev ntxhov siab, tawg corrosion, thiab lwm yam.

S355j2W + n phaj ua
1. Txiav
S355j2W + n Corten Hlau Daim Hlau tuaj yeem txiav los txiav kom cov hau kev siv ntau xws li ntshav txiav, lossis txiav laser txiav. Precise txiav kom ntseeg tau huv cov npoo thiab muaj qhov ntev, ua rau cov phiaj npaj kom txhij rau kev fabrication thiab sib dhos nrog minimal post {}} ua.
2. Kev sib sau
Cov khoom siv muaj cov khoom siv muaj peev xwm zoo thiab tuaj yeem ua kom tau los ntawm kev khoov, dov, lossis nias kom tau raws li cov qauv tsim tshwj xeeb. Txawm hais tias siv rau cov cuab yeej ua vajtse lossis cov txheej txheem sib xyaw, s355j2W + n steel tswj nws lub zog thiab cua sov tom qab tsim.
3. Drilling / Machining
S3555j2W + N Daim Hlau yog yooj yim drillable thiab machinable nrog cov khoom siv uas yooj yim. Qhov, slots, thiab kev cai nta tuaj yeem raug ntxiv kom tau kev tsim kho lossis engineering yuav tsum tsis muaj kev cuam tshuam kho tshuab lossis corrosion tsis kam.
4. Sib tsoo
Kev sib tsoo saum npoo thiab ua tiav kev ua tiav tuaj yeem thov kom ua tiav cov qauv du, cov khoom sib txawv lossis los npaj cov hlau rau kev kho sab nraud ntxiv. Tus txheej txheem no tau txhim kho kom zoo nkauj rov hais dua, tshwj xeeb rau cov ntawv kos duab thiab cov kev siv hniav uas zoo nkauj yog qhov tseem ceeb.
5. Kuaj
Txhua tus S35555555555555555555555555555555555555555555555555555555555 Cov phiaj no kom ntseeg tau tias txhua lub phaj tau raws cov qauv thoob ntiaj teb thiab muab cov kev ua tau zoo ib puag ncig hauv cov chaw xav tau.
