astm a656 grade 70 steel mill
General Info About A656. This grade steel is a high-strength, low alloy steel plate. Kloeckner offers A5656 in four different grades, including 50, 60, 70, and 80, and in three chemical requirements, type 3, type 7, and type 8. This specific steel has good formability, weldability, and notch toughness when in the as-rolled condition.
Material Properties The following material properties are ASTM specifications and will be confirmed on the Mill Test Report Grade Yield Point (ksi) Tensile Strength (ksi) Min. 2 Elongation % Type II & IV As-rolled 50 70 22 Type II & IV Annealed or normalized 45 65 22 Chemical Composition The following composition properties are ASTM specifications for these A606 grades. ASTM A656 - SSABThe ASTM A656 specification is the Standard Specification for Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate with Improved Formability for plates in applications where increased strength-to-weight ratios are required. Typical applications are construction equipment, crane booms, mobile man lifts, agricultural equipment, transport trailers, heavy vehicle frames and chassis, and rail cars.

The same inside bend radius cannot be used for all steel grades. astm a656 grade 80 welding - Carbon Steel platesASTM A656 A high-strength, low-alloy, hot-rolled structural steel plate utilized in structural applications where lighter weight and improved formability is critical. Applications include truck frames, crane booms, and rail car components. Made to Grades 50, 60, 70 and 80 the grade designating the yield strength.
A656 is the standard specification for hot-rolled structural steel, high-strength low alloy plate with improved formability. Lists two possible chemical variations for steels (grades 50, 60, 70, 80, and 100). Grades 80 and 100 are the highest volumes. More demanding property and chemistry requirements than A572.
