Q345GNH yog lub siab - lub zog huab cua steel phaj ua raws li Tuam Tshoj tus qauv GB / T 4171. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 345MPa, nws muab cov atmospheric corrosion kuj zoo heev los ntawm nws cov tooj liab-phosphorus alloy system (Cu-P-Cr-Ni).
Cov khoom siv txhim kho cov txheej txheem tiv thaiv xeb ruaj khov thaum raug huab cua, txo qhov kev saib xyuas zoo. Nws tuav zoo weldability thiab formability thaum muab kev txhim kho durability.
Cov ntawv thov ib txwm muaj xws li tsheb ciav hlau, txuas hniav, cov thawv thauj khoom, thiab cov qauv vaj tsev. Piv rau carbon steel, Q345GNH qhia 2-8 zaug zoo dua corrosion kuj nyob rau hauv ntau yam atmospheric ib puag ncig.
Cov hlau tshwj xeeb yog tsim rau cov ntawv tsis muaj xim sab nraum zoov uas yuav tsum tau ua kom ntev - lub sij hawm kev ncaj ncees. Nws tus nqi -kev ua tau zoo ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm kev tsim kho vaj tsev nyob hauv cov av noo, kev lag luam, lossis cov ntug dej hiav txwv.
