Hlau P265GH Rau Siab Hlab Nkoj
Thaum tshav kub kub resistant siab txog ntsha hlau. P265GH steel muaj qhov ua haujlwm zoo rau cov khoom lag luam uas yuav tsum tiv qhov tawm ntawm lub zog ntau dua 130N / mm2 ntawm 400ºC.
Cov hom hlau no tus cwj pwm yog weldability zoo. Lawv feem ntau siv rau kev tsim cov rhaub dej, lub nkoj siab thiab lub raj xa dej rau thauj cov kua dej kub. Lawv kuj muaj cov khoom kub zoo thiab tsis kub. Cov khoom yog ib txwm muab khoom raws li cov qauv txheej txheem.
