Oxidation Resistance of A588 Grade K Weathering Steel

A588 Grade K weathering steel is a high-strength and low-alloy structural steel that exhibits superior corrosion resistance in extreme environments. Exposure to air and water will greatly reduce the steel surface’s resistance to corrosion. This steel is often referred to as “steel that resists corrosion.” A588 Grade K is especially suitable for use in bridges, buildings and other structures where greater strength and improved corrosion resistance are required.

A588 Grade K weathering steel has superior resistance to atmospheric corrosion as compared to other steels. Its high tensile strength and corrosion resistance make it ideal for use in buildings, bridges, and other structures. A588 Grade K is composed of a specific combination of alloys that form an effective barrier to atmospheric corrosive elements. The combination of the alloys making up this grade of steel are iron, copper, chromium, nickel and phosphorus. The chromium content in A588 Grade K is especially beneficial, since it creates a passive layer that provides protection against corrosion.

Using A588 Grade K in outdoor applications can help add years of life to a structure by reducing the need for protective coatings, or painting. Despite its superior corrosion resistance, A588 Grade K steel will eventually naturally weather back to a light gray color.

Due to its superior oxidation and corrosion resistance, A588 Grade K can be used in a variety of extreme environments and conditions. It is especially useful in environments where the steel will be exposed to salt water, sea spray and other corrosive conditions. A588 Grade K is also resistant to air pollution, smoke, dew and other corrosive byproducts of industrial processes.

A588 Grade K also offers excellent fire retardance and ductility. These qualities make it suitable for use in buildings, bridges and other structures subjected to high temperatures. This steel is often used in areas where extreme temperatures are reached such as chimneys, fireplaces and even ovens.

A588 Grade K weathering steel offers excellent oxidation and corrosion resistance. This makes it ideal for use in a variety of harsh and extreme environments. It is resistant to air pollution, dew and other corrosive byproducts of industrial processes, as well as fire retardance and ductility.
