Cov khoom siv tshuaj ntawm 16MnDR boiler steel phaj
16MnDR boiler steel yog cov phaj hlau rau cov hlab ntsha uas tsis tshua muaj siab. Nws ua raws li GB3531 tus qauv thiab muaj qhov zoo toughness thiab weldability. Nws haum rau cov hlab ntsha siab ntawm -40 degree .
Hauv 16MnDR boiler steel phaj, "16Mn" txhais tau hais tias cov ntsiab lus manganese nyob nruab nrab ntawm 1.20% thiab 1.60%, "D" txhais tau tias tsis kub, thiab "R" txhais tau tias lub nkoj siab.
