What are the features of Q450NQR1 steel?

As a kind of weather-resistant steel, Q450NQR1 steel has good atmospheric corrosion resistance. After adding phosphorus, copper, chromium, nickel and other trace elements to the Q450NQR1 steel plate, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the matrix under the rust layer to slow down its corrosion. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal. Due to the existence of this dense oxide film, it prevents oxygen and oxygen in the atmosphere. The penetration of water into the steel matrix slows down the deep development of rust to steel materials and greatly improves the atmospheric corrosion resistance of steel materials. weather-resistant steel is a steel series that can be thinned, used, or simplified, so as to extend the life of products, save labor and consumption, and upgrade. Q450NQR1 steel is also a steel series that can be integrated into modern metallurgical new mechanisms, new technologies, and new processes to make it sustainable Development and innovation of the steel series.

Weather-resistant steel can be painted, bare or stabilized when used. The requirements for coating are the same as those of ordinary carbon steel. It should be pointed out here that this material can be used without painting, which is the outstanding advantage of weathering steel. In areas without serious air pollution or not particularly humid, weather-resistant steel can be directly exposed to the atmosphere without coating. Generally, after years, the rust layer will gradually stabilize, corrosion will no longer develop, and the appearance will be beautiful chocolate color. Because this kind of steel structure has no paint aging and other problems, it does not need painting and maintenance, which greatly reduces the maintenance cost, and of course, it avoids the losses caused by the influence of painting on use. weather-resistant steel is used as a building facade because of its unique color! Its own characteristics can greatly slow down the corrosion rate of steel plates, making the building easier to maintain, paint-free, and more environmentally friendly in the later use. Can never fade.

Q450NQR1 weather-resistant steel plate is a low-alloy steel series between ordinary steel and stainless steel. It can be developed and innovated continuously after incorporating modern metallurgical new mechanisms, new technologies and new processes. One of a series of steel grades with the cutting-edge level of super steel technology. weather-resistant steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the properties of high-quality steel such as toughness, ductility, forming, welding, abrasion, high temperature, fatigue, etc.; weather resistance is 2~ of ordinary carbon steel 8 times, the coating performance is 1.5~10 times that of ordinary carbon steel, which can be thinned, used or simplified. The steel has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving, which benefit component manufacturers and users. The products are used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.
