Strength and application of SA514 Gr P grade steel

Bridge steel plates are steel plates specially used to build railway or highway bridges. It is required to have high strength, toughness and bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel SA514 Gr P grade steel for tie-welding bridges should also have good welding performance and low notch sensitivity。

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel SA514 Gr P grade steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest SA514 Gr P grade steel processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain SA514 Gr P grade steel by rolling method.
