P355NH hlau

EN 10028 P355NH/NL1/NL2
Lub siab lub nkoj steel qib nrog zoo weldability thiab siab tsis kam mus nkig cracking, P355NH yog siv los ntawm lub ntiaj teb no fabricators rau zus tau tej cov siab hlab ntsha tso tsheb hlau luam rau khaws cia ntawm cov pa roj.

Lwm hom qib muaj xws li ...
NL1 - yog qhov zoo tagnrho rau siv hauv qhov kub thiab txias
NL2 - yog qhov zoo tagnrho rau kev siv tshwj xeeb hauv qhov kub thiab txias
P355NH yog cov qib zoo steel uas muaj qhov tsawg kawg nkaus tawm los ntawm 275-460 N / / mm² thiab daim hlau muaj nyob rau hauv Tshuag los ntawm peb lub tsev rau khoom.
