High Nitrogen Steel (HNS)
Army Bridges

Army Bridges

HNS Army Bridges

High Nitrogen Steel is also used in army bridges and in other structural applications, as it has high strength and good weldability.

The welding efficiency achieved is 80-90%, which is higher than other commercial grades available. Super Duplex Steel has a high strength-to-weight ratio which inhibits good structural integrity.

Other advantages: High corrosion resistance, Low DBTT temperatures enabling it to be used in naval applications.

General Characterstics

  • Armour steel optimally designed for blast protection
  • Perfect combination of strength & toughness as compared to other commercial grades available
