Qhov txawv ntawm P355GH thiab P355NH yog dab tsi?
P355GH: Cov hlau no yog tsim los rau siab - daim ntawv thov kub thiab muaj lub zog siab ntawm qhov kub txog li 500℃. P355NH: Cov hlau no yog tsim los rau qis- daim ntawv thov kub thiab yog tus cwj pwm los ntawm cov tawv tawv ntawm qhov kub thiab txias.
P355GH sib npaug rau ASTM cov khoom yog dab tsi?
P355GH siab lub nkoj hlau yog qhov sib npaug rau ASTM A516 Qib 70 thiab ASME SA516 Qib 70.
P355NH khoom yog dab tsi?
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.
Qhov kub ntawm P355NH yog dab tsi?
Nws txoj kev siv dav tshaj plaws yog nyob rau hauv daim ntawv thov ib puag ncig txog li 400 ºC. P355NH steel yog muab nyob rau hauv lub normalized mob. Lub normalizing kub yog 900 - 950 ºC, thiab nws yuav tsum tau muab tso rau hauv lub cub tawg tom qab kub sib npaug zos rau kwv yees li 1 feeb ib millimeter thickness ntawm lub phaj.
