CortenA, A588 Steel standard ASTM

CortenA, CortenB, A588, A588M-05 standard, ASTMA871M-03 order sheets

The full name is atmospheric corrosion-resistant high-strength low-alloy structural steel plate or atmospheric corrosion-resistant hot rolling steel, also known as corten steel. Corrosion-resistant steel is widely used in containers, power plants, chimneys, railway engineering and outdoor steel, such as steel for large outdoor sculptures, The tower has good corrosion resistance, heat resistance and low temperature resistance, good mechanical properties such as stamping and bending, good processability, and good plasticity. Combining mechanical properties and atmospheric corrosion resistance to manufacture boilers and structural parts that serve in atmospheric environments.

Three kinds of Corten-B weathering steel samples with the same chemical composition but different grain sizes were prepared by the same rolling process and different heat treatment methods. The relationship between the grain size and the atmospheric corrosion resistance of Corten-B weathering steel in industrial environments was studied by means of metallography, peripheral immersion, SEM microscopic analysis of rust layer cross-section, and AC impedance test. The results show that the grain size of Corten-B weathering steel decreases from 30 μm to 4 μm, the number of cracks and voids in the rust layer decreases correspondingly, the corrosion rate decreases, and the resistance Rr and reaction resistance Rt of the rust layer increase. , Atmospheric corrosion resistance is improved.

Corten steel, also known as Corten steel, is divided into two categories: CortenA and CortenB. It is the representative steel type of Cu-P series steel in the United States. It belongs to low-alloy high-strength atmospheric corrosion-resistant structural steel. The grades are Grade60 and Grade65. High-strength low-alloy steel plate for tubular construction or other suitable applications, available as hot rolled, normalized, quenched and tempered. The atmospheric corrosion resistance of this steel plate in most environments is inherently better than copper-containing or copper-free carbon structural steel plates. When fully exposed to the atmosphere, this type of steel is suitable for many purposes in its bare (uncoated) state. CortenA, CortenB, A588/A588M-05, ASTMA871M-03, Grade65, Grade60 Corten steel, as a high weather-resistant structural steel, is widely used in various fields. Different grades have different components.
