Krybar® is a specially designed reinforced steel bar for the construction of cryogenic LPG and LNG tanks in order to provide safety for cryogenic applications.

Due to its special composition and rolling process, Krybar® has a high ductility even at very low temperatures, down to -170°C (240‎°F). ArcelorMittal has been producing Krybar® since 1980. Since then, the product has been used in more than 300 tanks worldwide.


The latest Krybar® product, Krybar®- 620, is based on over 40 years of experience during the production of its predecessor, the Krybar®- 165. The Krybar®- 620 complies with EN 14620 and the Krybar-165 with the BS7777 and with EN 14620.

We offer a range of Krybar® grades, depending on the design temperature of the tank. Our offer includes:

  • For LNG tank design according to BS7777: Krybar® - 165 and EN 14620: Krybar® - 620
