What are the common types of weathering steels?

Weathering steel plate is a kind of steel with excellent weathering performance, and its main components are iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, copper and other elements. Common types of weathering steel plate are Corten A, Corten B, SPA-H, SPA-C and so on.

Corten A is a common type of weathering steel plate, its main components are Fe, C, Si, Mn, P, S, Cr, Ni, Cu and other elements.Corten A steel plate county has excellent weathering performance, can be used in the atmosphere for a long time without losing its original strength and toughness. Therefore, Corten A steel plate also has good corrosion resistance, can resist acid rain, seawater and other corrosive environment erosion. For example, in this office building in Russia, the facade uses weathering steel panels bent up and down and overlapping each other to form a bamboo basket-like weaving effect.

Corten B is another common type of weathering steel plate, its main components are similar to Corten A, but slightly different in the content of chromium, nickel and other elements. CortenB steel plate has similar weathering and corrosion resistance with Corten A, but its strength and toughness is slightly higher than that of Corten A. For example, after more than a hundred years of the synagogue rain and snow to usher in the renovation of its side to add weathering steel. The synagogue was renovated after more than 100 years of rain and snow, and a weathering steel extension was added next to it. The color of the new building's weathering steel and its geometric openwork design complement the synagogue.

SPA-H is a Japanese standard type of weathering steel plate whose main components are iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, etc. SPA-H steel plate has excellent weathering and corrosion resistance properties, and can be used in the atmosphere for a long time without losing its original strength and toughness. In addition, SPA-H steel plate has good weldability and processability, and is suitable for a variety of complex processing and manufacturing processes. For example, the exterior wall of this residence consists of weather-resistant steel panels and cedar wood veneer, two materials that echo each other in color and complement the surrounding forest, providing a warm visual experience.

SPA-C is another Japanese-standard weathering steel plate type with a similar main composition to SPA-H, but with slight differences in the content of chromium, nickel, etc. SPA-C steel plate has similar weathering, corrosion resistance, weldability, and machinability as SPA-H, but its strength and toughness are slightly lower than that of SPA-H. For example, the flyover at this school is made of weathering steel, forming an art gallery and viewpoint.

Weathering steel plate is a type of steel with excellent weathering and corrosion resistance properties, and its models include Corten A, Corten B, SPA-H, SPA-C, etc. Different models of weathering steel plate differ slightly in composition, strength, toughness, weldability, workability, etc. You can choose the right model according to your specific needs.
