Q310GNH Huab cua resistant steel phaj muaj txheej tiv thaiv xeb tiv thaiv atmospheric corrosion, GB / T 4171 Q310GNH Huab cua resistant steel phaj tuaj yeem siv rau hauv kev tsim tsheb, txuas hniav, yees, ntim thiab lwm yam hlau tsis tshua muaj- alloy structural steel.
Piv nrog cov pa roj carbon steel, Q310GNH hlau tau zoo dua corrosion kuj nyob rau hauv cov huab cua. Piv nrog rau cov hlau tsis muaj steel, tsuas yog cov kab ntawm cov ntsiab lus alloying, alloys xws li huab cua tiv thaiv cov hlau ntawm tag nrho phosphorus, tooj liab, chromium, npib tsib xee, molybdenum, niobium, vanadium, titanium, thiab lwm yam tsuas yog ob peb feem pua.
