EN 10025-3 (低温级)
Low-temperature structural steel profiles
Steel Grades: S275NL, S355NL, S420NL, S460NL
Widely used in polar engineering structures, cryogenic storage tank supports and LNG plant steel structures, as well as refrigeration plant frames, cryogenic equipment platforms and support structures. With its good low-temperature toughness and weldability, it is suitable for steel structure load-bearing components and supports welded in cold and cryogenic environments, ensuring long-term stable service and structural safety.
ASTM A517 (低温级)
Low-temperature tempered high-strength steel profiles
Steel Grades: Gr.A, Gr.B, Gr.E, Gr.F, Gr.H, Gr.P, Gr.Q, Gr.S (低温级)
It is mainly used for cryogenic pressure vessel supports, polar engineering structures and heavy cryogenic equipment frames. It is also used for cryogenic equipment bases, platforms and supports that bear heavy loads. With its high strength and excellent low-temperature toughness, it is suitable for welded high-strength steel structural load-bearing components in cold and cryogenic environments, reliably bearing heavy loads and ensuring long-term structural stability and safety.
