Corten B and S355J2WP are two steel grades that are often compared due to their similarities in weather resistance properties. Both these grades are popular choices for construction and architectural applications, especially when the infrastructure is exposed to harsh weather conditions. Corten B is a weather-resistant steel grade that contains copper, chromium, nickel, and phosphorous as alloying elements. It forms a protective oxide layer (patina) on its surface when exposed to the atmosphere, which acts as a barrier against further corrosion. This patina gives Corten B its distinctive rusty appearance, making it a popular choice for outdoor sculptures and architectural structures. On the other hand, S355J2WP is also a weather-resistant […]
