building material astm a242 a588 gr. b corten steel sheet price

ASTM A242 and A588 are the two most common structural steel specifications used for the production of Corten steel sheet. While ASTM A242 is the specification for general structural purposes, A588 is the specification for higher strength applications. These two specifications are often used together to produce weathering steel sheet for a variety of applications.

The major difference between these two specifications lies in the chemical composition and mechanical properties of the materials. ASTM A242 consists of a lower amount of alloying elements and results in a lower tensile strength than A588 grades. Additionally, A242 typically contains higher levels of manganese, phosphorous and sulfur than A588 grades. This combination can result in better atmospheric corrosion resistance in certain applications.

On the other hand, A588 contains higher levels of chromium, copper, nickel and other alloying elements, which give it superior corrosion resistance compared to A242 grades. However, its higher strength characteristic means it is typically more difficult to form and weld than A242 grades.

Given the different mechanical and chemical properties of both materials, the price of Corten steel sheet produced with each specification can vary significantly. Typically, Corten steel sheets produced under these two specifications will be priced according to the complexity of the manufacturing process and the levels of alloying elements used. In many cases, Corten steel sheets using ASTM A242 will be less expensive than those using A588 due to its lower tensile strength and lower amount of alloying elements.

Overall, the price of Corten steel sheet will depend on the type of grade and chemical composition used in the manufacturing process. Furthermore, the geographical location and availability of resources will also affect the cost of Corten steel sheet. Ultimately, customers should collaborate with a knowledgeable supplier who is familiar with the specific application to ensure the right specifications and grade of Corten steel sheet are used in the project.
