Q450NQR1 Weathering Steel Plate Product Manufacturer
What is weathering steel?
It is characterized by the following alloy composition and weight percentage content of weathering steel: C:≤0.12, Si:0.25~0.75, Mn:0.2~0.5, S ≤0.02, P:0.06~0.12, Cu:0.25~0.5, Cr:0.3~1.25, Ni:0.12~0.65, and the rest are Fe and trace elements. By alloying Cu, Mn, Si, Al, etc., and simply adjusting the content of some elements of ordinary low carbon steel (Q235 steel), without changing the production process conditions of Q235 steel, you can produce good atmospheric corrosion resistance, comprehensive mechanical properties of economic weathering steel.
Weathering steel (i.e. atmospheric corrosion resistant steel) can be sustainably developed and innovated after incorporating new mechanisms, new technologies and new processes in modern metallurgy, and is one of the series of steel grades at the forefront of the world's super steel technology. Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements, which has the characteristics of high quality steel such as toughness, plastic extension, forming, welding, abrasion, high temperature, fatigue, etc.; weathering resistance is 2~8 times of ordinary carbon steel, painting is 1.5~10 times of ordinary carbon steel, which can be used in thinning, bare or simplified painting. The steel has the characteristics of rust resistance, corrosion resistance and life extension, thinning and energy saving, so that the component manufacturers and users benefit. Weathering steel products are used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media and other structural parts.
What are the characteristics of weathering steel?
It refers to low-alloy structural steel with a protective rust layer to resist atmospheric corrosion and can be used to manufacture steel structures such as vehicles, bridges, towers and containers. Compared with plain carbon steel, weathering steel has better resistance to corrosion in the atmosphere. Compared with stainless steel, weathering steel only trace amounts of alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., the total alloying elements account for only a few percent, unlike stainless steel, up to ten percent, so the price is cheaper.
