What is the A709-50F-2 steel?

A709-50F-2 steel plate is structural steel for bridges. 50 is a structural steel for bridges with a yield strength of 345MPa, and -2 means: Charpy V-notch impact test area code

Equivalent: GB/T 714 standard: Q345q

Category: high-strength low alloy steel structural steel

Mechanical properties of A709-50F-2 steel plate:

Application scope of A709-50F-2 steel plate:

A709-50F-2 high-strength low alloy steel plate is used to make road bridges and railway bridges (including cross-sea bridges) with riveted and bolt-welded structures. It is required to have high strength and sufficient toughness, low notch sensitivity, good low temperature toughness, anti-aging sensitivity, fatigue resistance and welding performance. The main domestic steels used are low-alloy high-strength steels such as Q345q, Q370q and Q420q.
