K-TEN610CF: quenched and tempered 610 N/mm² class high-strength steel plate for welded structures with low crack susceptibility (Crack-Free Steel)

1. Features

• In additions to the advantages offered by standard-type K-TEN, Crack-Free Steel offers greatly reduced preheat temperatures and highly improved weldability.
  • Preheating in welding construction can be greatly reduced.

2. Major corresponding standards

• JIS G3106 (Rolled Steel for Welded Structures) SM570Q
• JIS G3115 (Steel Plates for Pressure Vessels) SPV490Q
• WES 3001 (Weldable High-Tensile Strength Steel Plates) HW490Q
• WES 3009 (Supplementary Requirements for High-Strength Steel Plates with Low Susceptibility to Weld Cracking) HW490Q-CF

3. Applications

• Application to various welded structures including spherical tanks, bridges, penstocks, and off-shore structures can be expected.
