ASTM SA656 is “Standard Specification for Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate with Improved Formability” for Bridges, Buildings, Rolling Stock and Ships. There are five grade in the standard ASTM SA656, and one is
SA656 Grade 50. Katalor always keeps thousands of high-strength low-alloy plates and steel structures including
SA656 Grade 80.

SA656Grade 50 structural steel plate is used in truck frames, brackets, crane booms, rail cars, and similar applications. A656Gr.50 steels that conform to this specification offer improved formability. These steels are normally furnished in the as-rolled condition. The type and strength grade furnished is as agreed upon between the manufacturer and the purchaser.
For SA656 Gr.50 plates produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements of SA656 Grade 50 steels including additional testing requirements and the reporting of additional test will meet the Specification A6/A6M apply.
