Shipbuilding material nm400 weathering steel 5000tons in Italy
Q550D Application: This steel is mainly used in steam turbines for main steam pipes with steam parameters up to 540℃, turning guide vane ring, steam turbine baffle, baffle outer ring, and various superheater tubes, ducts and pipes with tube wall temperature ≤570℃ The corresponding forgings.
S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. NM400 weathering steel, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, NM400 weathering steel.
