maraging

The second generation design (P2) originally relied on a stronger material called maraging steel which provides a more efficient rotor design and improved speed, hence yielding a higher Separating Work Unit (SWU).

A year earlier, a small company in the Chinese port city of Dalian provided Iran with a range of sensitive materials, including graphite, tungsten copper, tungsten powder, high - strength aluminum alloys and high-strength maraging steel, again for its nuclear program.

These experts believe Tehran is now close to having exhausted its supply of maraging steel for the IR-1 centrifuges and the more advanced machines.

Other key components in Iran's centrifuges, called "bellows," which serve to balance and stabilize the fast-spinning rotors, are made of high-quality maraging steel — a high-strength yet malleable form which is in even shorter supply internationally than carbon fiber, according to nuclear experts.

Japan is a major supplier of both maraging steel and carbon fiber.

One topic of discussion was how the network obtained maraging steel, an alloy that is on restricted export lists worldwide, for use in the P-2 rotors the factory was gearing up to produce for Libya.
