What is the minimum yield point of Corten steel?

Corten steel, also known as weathered steel, is designed to develop a stable rust-like appearance when exposed to the weather over time. This material is noteworthy for its unique properties, including high strength and enhanced resistance to atmospheric corrosion.

The minimum yield point of Corten steel is indeed around 34 kg/mm² (or 340 MPa). This characteristic makes Corten steel suitable for various structural applications, particularly in outdoor environments where exposure to moisture and varying temperatures is common.

Understanding the material's yield point is crucial for engineers and designers, as it helps in determining the load-bearing capacity of structural components. The higher yield point indicates that Corten steel can withstand significant stress before deforming, thus providing an additional margin of reliability in construction and structural applications.

In contrast, the other values listed do not correspond to the standard mechanical properties of Corten steel, emphasizing the importance of adhering to specified material properties in engineering and construction standards.
