Plaque d'acier corten A871

Corten Steel Plate A871 is another type of high-strength, low-alloy (HSLA) structural steel that is specifically designed to offer superior resistance to atmospheric corrosion. It belongs to the weathering steel family, like ASTM A588 and A242, but is specially developed for applications requiring high strength and long-term durability in environments where atmospheric corrosion is a concern.

ASTM A871 is a specification for high-strength, low-alloy structural steel plates with improved corrosion resistance. This steel is part of the Corten family and is especially suited for applications requiring long-term resistance to atmospheric corrosion and superior strength in structural projects. It is designed to reduce the need for maintenance by forming a stable rust-like

appearance, which protects the steel from further corrosion.

ASTM A871 is available in two grades:

• Grade 60 and Grade 65, where the numbers represent the steel’s minimum yield strength in ksi (thousand pounds per square inch).
