High-tensile / Excellent Quality HAZ Toughness Plate
- The needs of high tensile steel are growing up as the size of facility increases.
- NIPPON STEEL has wide range Pre-Qualification material with high toughness for offshore structure using advanced technology.
- NIPPON STEEL has supplied offshore structural steel for various projects all over the world.
- NIPPON STEEL has applied the TMCP(*1) process to offshore structural high tensile steel with excellent weldability and HAZ(*2) toughness for the first time in the world.
(*1:Thermo Mechanical Control Process. *2:Heat Affected Zone) - The shift to high tensile steel leads the reduction in the size and weight of steel structure. As the result, it is possible to reduce “Distribution and installation cost” while mounting equipment.
Features
- Excellent TMCP technology
- Improvement of HAZ toughness
- Good weldability
- World-class product lineup
Benefits of use
- Compatible with the needs in place for high strength structures
In addition to Gr50 and Gr60 steel plates specified by API standards, we have newly developed Gr80 steel plates, being the first in the world to put it into practical use. - Weight reductions
Allows for capacity in TOPSIDE-loaded equipment.
