Characteristics of DIN17102 WStE 315 Steel
Classification and Low-Temperature Performance:
The DIN17102 standard encompasses multiple steel grades, where "WStE" denotes the high-temperature series steel, contrasting with the low-temperature series (TStE) and special low-temperature series (EStE). The high-temperature series (WStE) exhibits a minimum 0.2% proof stress value under elevated temperatures, making it suitable for equipment and structural components operating in high-temperature conditions. Based on its series characteristics, its low-temperature performance may be inferior to that of the low-temperature series (TStE) and special low-temperature series (EStE), with the latter maintaining high impact energy even at temperatures ranging from -50°C to -60°C.
Chemical Composition and Strength Characteristics:
As a German standard low-alloy high-strength steel, WStE 315 achieves a balance between strength and toughness through precisely controlled chemical composition. Its primary elements include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and may incorporate microalloying elements such as niobium (Nb) and titanium (Ti) to refine grain structure. It has a minimum yield strength of no less than 315 MPa, with a typical tensile strength range of 440–560 MPa.
