Current S420NL Price at China Market

As of November 2025, the price of S420NL steel plates in the China market is approximately $700 per ton, based on supplier quotes for high-strength steel plates. This price is typically FOB China for minimum orders of 1 ton, with variations depending on thickness, quantity, and market conditions. General hot-rolled steel plates range from $580–720 per ton FOB, but S420NL, as a specialized HSLA grade, commands a premium due to its fine-grain normalization and low-temperature properties. Prices may fluctuate with raw material costs, demand in infrastructure projects, and global steel trends. For bulk orders or custom specifications, contact Gangsteel for competitive quotes.

 

What is S420NL Steel?

S420NL steel, designated as 1.8912 under EN 10025-3, belongs to the family of weldable fine-grain steels. The "NL" suffix indicates normalized delivery with low-temperature impact testing at -50°C (27 J minimum longitudinal), making it suitable for arctic or sub-zero environments. Compared to S420N (tested at -20°C), S420NL provides superior cold toughness without sacrificing strength.

Gangsteel produces S420NL plates in thicknesses up to 250 mm, with controlled chemistry for optimal CEV (≤0.48) and weldability. Our plates undergo rigorous testing, including ultrasonic and Charpy impact, to meet global standards.

Heat Treatment Guide for S420NL Steel

S420NL is supplied in normalized (+N) condition, involving heating to 880–920°C, soaking, and air cooling to refine grain structure.

  • Preheating for Welding: Not required ≤50 mm; 100–150°C for thicker (CEV ≤0.48).
  • PWHT: Optional 550–650°C stress-relief.
  • Hot Forming: >850°C; re-normalize if <720°C.

Follow EN 1011-2. Gangsteel optimizes for minimal heat treatment.

 

Applications of S420NL Steel

  • Heavy Engineering: Cranes, frameworks.
  • Infrastructure: Bridges, offshore.
  • Construction: Shipbuilding, vessels.
