Weathering steel is a group of steel alloys that are designed to form a durable oxidation resistant patina on its surface to protect the underlying steel. Grade A weathering steel, such as ASTM A588, is designed to form a protective layer that reduces corrosion, and is commonly used in construction applications. It is important to understand the difference between weathering steel and non-weathering steel to ensure the right steel is used in the right application.
The ASTM A588 is a standard specification for high-strength, low-alloy structural steel products that exhibit increased atmospheric corrosion resistance and are intended for construction use. This grade of steel is designed to form a protective layer that reduces surface-level corrosion and increases the lifespan of the structure. The ASTM A588 is the standard specification for Grade A weathering steel, and is a proof-of-concept for advanced weathering grade steel products.
The ASTM A588 International Certification Program certifies that products produced have gone through rigorous tests to meet the highest standards of quality and performance. This certification includes a variety of tests to assess corrosion resistance, condition, and chemical composition of the material. Some of these tests include chemical corrosion resistance tests, atmospheric exposure corrosion resistance tests, accelerated weathering tests, and environmental exposure corrosion tests. The results show that Grade A weathering steel has superior outdoor corrosion resistance and an increased lifespan when compared to non-weathering steel.
The ASTM A588 also has specific requirements and standards that must be met in order to be compliant. These standards include chemical composition, mechanical properties, and product quality requirements. Grade A weathering steel must contain a minimum of 0.2% copper and must have tensile strength between 65-85 ksi and yield strength between 36- 50 ksi. Additionally, it must have a Brinell hardness of 167-229. The product must also meet the ASTM’s regulations for marine exposure and high-temperature environments.
The ASTM A588 provides an international standard for Grade A weathering steel, as well as stringent tests to ensure the highest quality products are produced. This certification is a testament to the durability of this material, and provides the assurance that products made with Grade A weathering steel will stand the test of time.
