No, maraging steels are ones that ultra-low carbon steels. The carbon content in normal steel determines the hardness.

They use either Nickel-Titanium or Nickel-Molybdenum as the hardening component and keep the carbon content as low as possible.

Maraging steels are often used in low-temperature applications because they retain their toughness at lower temps than carbon-steel.

With respect to Iran and North Korea, maraging steel tubes were one of the embargoed products.
