Nws yuav tsum raug sau tseg tias cov khoom tshwj xeeb yuav txawv nyob ntawm cov txheej txheem tsim khoom thiab cov qauv.

Cov qib steel P355NL1 thiab P355NL2 muaj kev siv dav hauv ntau qhov chaw vim lawv cov khoom muaj txiaj ntsig.

Hauv kev lag luam hluav taws xob, lawv feem ntau siv rau hauv kev tsim cov roj thiab cov kav dej. Cov kav dej no yuav tsum tiv taus siab thiab hnyav ib puag ncig. Lub zog siab thiab zoo corrosion kuj ntawm P355NL1 thiab P355NL2 steels tuaj yeem ua kom muaj kev nyab xeeb ntawm cov kav dej, thauj cov khoom siv hluav taws xob zoo thiab txo qhov kev pheej hmoo ntawm cov dej xau.

Hauv kev lag luam tshuaj lom neeg, lawv tau siv los tsim ntau yam khoom ntim tshuaj thiab khoom siv, xws li reactors thiab cia tank. Lawv tuaj yeem tiv taus qhov yaig ntawm cov tshuaj lom neeg, lav kev ruaj ntseg thiab kev nyab xeeb ntawm cov txheej txheem tshuaj lom neeg.

Hauv kev tsim khoom siv tshuab, lawv tuaj yeem ua haujlwm los tsim ntau yam khoom siv kho tshuab, xws li shafts thiab gears. Lawv cov khoom siv kho tshuab zoo heev ua rau cov khoom siv tiv thaiv cov khoom tseem ceeb thiab kev ua haujlwm nyuaj, txhim kho kev ntseeg tau thiab kev pabcuam lub neej ntawm cov cuab yeej siv tshuab.

Hauv kev tsim cov boilers thiab cov hlab ntsha siab, P355NL1 thiab P355NL2 steels kuj yog kev xaiv. Lawv tuaj yeem hloov mus rau qhov chaw ua haujlwm kub thiab muaj zog siab, ua kom muaj kev nyab xeeb ntawm cov boilers thiab cov hlab ntsha siab thiab tiv thaiv cov xwm txheej txaus ntshai xws li tawg.

Hauv kev tsim kho, lawv tuaj yeem siv los tsim cov qauv hlau loj, xws li txuas hniav thiab cov kev txhawb nqa ntawm cov tsev siab. Lawv lub zog siab tuaj yeem nqa qhov hnyav hnyav thiab sab nraud, muab kev txhawb nqa ruaj khov rau cov tsev.

Tsis tas li ntawd, nyob rau hauv kev lag luam shipbuilding, lawv yog siv los tsim cov qauv hull thiab lwm yam khoom. Lawv tuaj yeem tiv taus corrosion ntawm seawater.
