StE315 steel plate application planning:

generally used in the manufacture of various types of construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, all kinds of cranes, Coal mine hydraulic supports and other mechanical equipment and other structural parts.

This kind of steel, due to its suitable hardenability, after suitable metal heat treatment, the microstructure is uniform sostenite, bainite or very fine pearlite, so it has high tensile strength and yield ratio (generally around 0.85), high toughness and fatigue strength, and low toughness-brittleness transition temperature, which can be used to manufacture machine parts with large cross-sectional dimensions.
