P355NH Siab Vessel Steel Phaj Qhia ntxaws qhia
P355GH steel phaj rau cov hlab ntsha siab yog cov khoom lag luam European txheem steel nrog kev ua haujlwm zoo rau kev kub siab, siab thiab corrosion. Nws yog feem ntau siv rau hauv kev tsim cov khoom siv siab rau ntau lub nkoj siab thiab boilers, xws li hauv cov roj av, tshuaj, hluav taws xob thiab boiler industries. Tsis tas li ntawd, P355GH steel phaj kuj tseem tuaj yeem siv los tsim cov kav dej, cov hlab ntsha, cov roj tso tsheb hlau luam, cov roj tso tsheb hlau luam, cov tshuab hluav taws xob nuclear thiab lwm yam khoom siv siab.
Cov yam ntxwv ntawm P355GH Siab Vessel Steel Phaj yog raws li hauv qab no
1. Lub zog siab: P355GH steel phaj muaj lub zog muaj zog thiab lub zog tensile, uas ua rau nws zoo dua lub peev xwm thauj khoom thiab kev nyab xeeb hauv kev tsim cov hlab ntsha siab.
2. Zoo weldability: P355GH steel phaj tsis tshua muaj kev tawg thiab deformation thaum welded, uas ua kom zoo ntawm cov vuam.
3. Kev ua haujlwm zoo: P355GH steel phaj yog ib qho yooj yim rau kev ua tiav rau hauv ntau yam duab thiab ntau thiab tsawg kom tau raws li kev tsim khoom sib txawv.
