What are the specifications of "weathering steel"?

What are the common specifications of weathering steel plate?

Weathering steel is a very common steel plate in production, many people have always been more concerned about its specifications, today we will learn about what are the specifications of weathering steel plate?
Weathering steel is added a small amount of alloying elements Cu, P, Cr, Ni, etc., to form a protective layer on the surface of the metal to improve the ability to resist atmospheric corrosion steel.
Weather resistant structural steel is divided into two categories: high weather resistant steel and welded weather resistant steel. Weather resistant structural steel is resistant to atmospheric corrosion, and welded weather resistant steel has good welding performance. Weather-resistant structural steel is 28 times more resistant to atmospheric corrosion than ordinary steel.
Therefore, where there is a technical and economic basis, better results can be achieved by using weathering steel for important structures exposed to atmospheric environments or moderately aggressive media environments.

What is the general weathering steel specification and thickness?

Specification of weathering steel plate 1.

Height: 1.2 mm - 80.0 mm
Width: 800-3000 mm
Material: Q235NH, Q235GNH, Q295NH, Q460NH, Q295GNH, Q295GNH, Q345GNH, Q345GNHL, Q390GNH, Q450NQR1, q
Implementation basis: GB/T4171-2008, TB1979-2003/2014

Specification of weathering steel plate 2.

Height: 0.8 mm-400 mm
Width: 1000-3000mm
Material: 10 #, Q235B, Q235C, 16Mn, Q345B, Q345C, Q345E, Q245R, Q345R, 20 #, 45 #, 40Mn, 500
Weather resistant steel plate has the ability to protect rust against atmospheric corrosion and can be used to manufacture low-alloy structural steel for vehicles, bridges, towers, containers and other steel structures. At the same time, it has the characteristics of rust resistance, prevent parts corrosion, prolong life, thinning, reduce consumption, save energy, etc.
Weathering steel has better corrosion resistance in the atmosphere than ordinary carbon steel. Compared with stainless steel, weathering steel only phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and other trace alloying elements, the total amount of alloying elements is different from stainless steel, reaching more than 10%, so weathering steel plate is cheaper, cost-effective and worth choosing
Weathering steel in the integration of modern metallurgical new mechanisms, new new technology to achieve sustainable development and innovation, is one of the world's technical frontier level of the series of steel.
