FAQ
Q: What is ASTM A588 steel grade?
A: Available in three grades: A, B and K. Often referred to as Weathering steel. Has properties similar to COR-TEN® steel. Ideal for welding, riveting or bolting in construction applications, primarily for bridges and buildings.
Q: What is the difference between ASTM A588 and A606?
A: The difference in our products is: A606-4 is considered weathering steel sheet with thicknesses beginning at 22 Gauge and thicker available up to 3/16". We stock A606-4 in flat sheets, coil, and panels. A588 is available in steel plate and starts at 3/16" thickness and increases up to 5" thickness.
Q: What is ASTM A588 steel equivalent to?
A: The ASTM A588 grade A plate is equivalent to Corten A steel plate. ASTM A242 plate is equivalent to Corten B. Compared with common low alloy high strength steel such as A572 Grade 50, ASTM A588 and ASTM A242 has advantages of weathering resistant performances.
Q: What is the ASTM standard for Corten Steel?
A: The ASTM specifications include A588, A242, A606-4, A847, A871-65, and A709-50W, with Cor-ten® standing out as the primary trademarked product. These specifications set the standards for weathering steel, ensuring its resilience against the elements and long-lasting corrosion resistance.
Q: What is the difference between A588 and A242?
A: A242 (Corten A): Specifies a minimum tensile strength of 63 ksi (435 MPa) for Grades 1 & 3, and 70 ksi (485 MPa) for Grade K (a newer, stronger variant). A588 (Corten B): Specifies a minimum tensile strength of 70 ksi (485 MPa) for all grades. This is the most significant mechanical difference.
