The Development of a New HSLA As - Hot - Rolled Bar Product

A new as-hot-rolled HSLA steel has been developed for application as round and flat bars. This material possesses a minimum yield strength of 80 ksi coupled with good bendability, weldability, and fatigue performance. This material offers design engineers and manufacturers the flexibility to upgrade from lower-strength materials to (a) increase load carrying capability of their present structures or, (b) realize important weight and energy savings by going to lighter section sizes at present load ratings. It also enables them to take advantage of its high strength to replace more costly heat treated grades.
