Low temperature steel plates are designed for service in cryogenic and sub-zero temperature environments where conventional carbon steel becomes brittle. We supply ASTM A516 Grade 70N, EN S355NL, S420NL, GB 16MnDR, and 09MnNiDR grades with guaranteed Charpy V-notch impact properties at temperatures down to -60°C. These plates are used in LNG storage tanks, cryogenic equipment, cold region structures, and low temperature pressure vessels.
EN S420NL is a premium normalized high-strength structural steel plate (420 MPa yield) providing exceptional fracture toughness at -50°C and superior weight-to-strength efficiency.
