NM450 steel phaj yog abrasion tsis kam phaj nrog zoo hardness.Cov no yog heev xav tau nyob rau hauv fabrication industries.Thaum txiav txim siab txo qhov chaw ib puag ncig vim nws cov cuab yeej tiv taus cov khoom no yog qhov tseem ceeb rau kev txo qis ib puag ncig.Cov hlau phaj no muab kev zoo weldability.Cov phaj no muaj qhov ua tiav zoo heev uas muaj kev ua tau zoo hauv oxidizing ib puag ncig.Qib yog sib xyaw nrog cov cuab yeej zoo tiv thaiv corrosion.Qhov no ua haujlwm siab hauv kev txo qhov chaw txawm tias kub kub.Qib yog ob qho tib si sib nqus thiab tsis sib nqus hauv qhov xwm txheej.Hlau daim hlau tiv thaiv kev cuam tshuam ntawm kev cuam tshuam kev thauj khoom thaum kub siab dua.
Feem ntau, daim hlau muaj cov qauv zoo sib xws tab sis nrhiav kev ntseeg siab ntawm cov khoom tsim ua kev sim.Feem ntau IGC xeem, kuaj cov khoom zoo, kuaj txhua yam, kuaj hardness, tshuaj ntsuam xyuas, pitting kuj kuaj.Txawm li cas los xij, cov neeg siv khoom tuaj yeem thov ib qho kev xeem tshwj xeeb raws li lawv qhov xav tau.Tsis tas li ntawd, cov neeg sab nrauv ua tiav qhov kev soj ntsuam zaum kawg ntawm NM450 steel daim hlau rau 100% kev ruaj ntseg zoo.
