Core Traits of GB/T Q500NH Corten Steel​

 

1 It is a high-strength atmospheric corrosion-resistant (Corten) steel strictly produced in line with China's GB/T 4171-2008 standard, occupying a key position in the medium-to-high strength segment of weathering steel. The designation carries clear performance implications: "Q" represents yield strength, "500" indicates a minimum yield strength of 500 MPa for plates ≤16mm thick, and "NH" stands for "weather-resistant" in Chinese. This positioning makes it an optimal choice for industrial scenarios requiring both heavy load-bearing capacity and corrosion resistance.​

 

2 Its performance advantages originate from a sophisticated chemical composition. It contains 0.20-0.55% copper (Cu), 0.30-1.25% chromium (Cr), and 0.12-0.65% nickel (Ni) as core corrosion-resistant elements, plus trace niobium (Nb) and vanadium (V) for strength enhancement . When exposed to air, moisture, or industrial pollutants, these elements react to form a dense, adherent oxide patina that blocks further corrosion-eliminating the need for frequent anti-corrosion coatings . With carbon content ≤0.16%, it also avoids brittleness risks common in high-strength steels.
