A242 Type 1: High-performance weather-resistant structural steel

A242 Type 1 is a high-strength low-alloy structural steel that meets the ASTM A242 standard. It has good atmospheric corrosion resistance by adding alloying elements such as chromium, nickel, and copper. In the atmospheric environment, a dense protective rust layer can be formed on its surface, which can effectively prevent further rusting of the steel.

This steel has many characteristics. On the one hand, it has excellent weather resistance. In harsh environments such as high humidity, high salt coastal areas or industrial pollution, the corrosion rate is much lower than that of ordinary carbon steel, and the service life can be extended several times. On the other hand, it has excellent mechanical properties, and the yield strength can generally reach 345MPa - 450MPa. It can withstand complex static and dynamic loads, and has a certain elongation and good toughness.

In terms of size specifications, the thickness of A242 Type 1 steel is usually between 2mm and 120mm. Its main forms include steel plates, steel strips, profiles, bars, etc., which can meet different processing needs.

In terms of application, it is often used in curtain wall frames and roof trusses in the construction field. Steel beams and bridge towers in bridge construction also often use this steel material, which can reduce the anti-corrosion coating process. In addition, it is also widely used in industrial facilities, such as open-air trestles and large oil tank supports, to ensure efficient and stable operation in harsh industrial environments.
