At the same time of doing well in Q235NH alloy steel sheet production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the Q235NH alloy steel sheet technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Weathering steel alloys like Corten A/B were developed for hard-wearing industrial applications to eliminate the need for costly finishing and refinishing. Primary alloying elements in the steel (copper, chromium, and nickel) actively cause atmospheric corrosion at the surface to generate a hard, corrosion-resistant patina. This protective layer actively and continuously regenerates when Corten steel Q235NH alloy steel sheet is subjected to weathering influences, including airborne pollutants, humidity, and rain.

Oxygen (O) is a harmful element in steel such as Q235NH alloy steel sheet. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
