Qhov chaw ua haujlwm ntawm lub nkoj yog qhov hnyav heev. Lub plhaub plhaub yuav tsum tau tiv thaiv corrosion ntawm seawater, marine organisms thiab microorganisms; lub hull kuj yuav tsum tiv taus cua loj thiab yoj shocks thiab alternating loads; cov duab ntawm lub nkoj ua rau nws cov tshuab ua haujlwm ntau dua. Complex, yog li cov kev cai rau steel rau hull qauv yog nruj dua.
Ua ntej ntawm tag nrho cov, zoo toughness yog qhov tseem ceeb tshaj plaws tsom xam ntawm marine steel daim hlau. Tsis tas li ntawd, marine steel daim hlau xav tau lub zog siab, zoo corrosion kuj, zoo weldability, formability thiab nto zoo.
Tau kawg, txhawm rau kom ua tau zoo thiab muaj zog txaus, marine steel daim hlau xav tau cov ntsiab lus ntawm chromium thiab manganese yuav tsum siab dua 2.5 feem pua, thiab tseem muaj cov kev cai nruj ntawm cov ntsiab lus ntawm cov ntsiab lus carbon hlau, thiab lawv yuav tsum tau tsim los ntawm steel mills pom zoo los ntawm lub nkoj soj ntsuam department.
Tau hais ntau, nws puas zoo dua los xaiv cov hlau zoo tib yam rau marine steel daim hlau? Los yog stainless hlau zoo dua?
Qhov tseeb ... nws yog ib qho tsim nyog los xaiv stainless hlau phaj lossis zoo tib yam steel phaj raws li qhov sib txawv ntawm lub nkoj xav tau.
