Armco 5% & 90/°

Nickel Steels can offer significant cost 1 savings for

LNG vessels

For cryogenic construction involving transportation, processing, storage and distribution^ of liquefied natural gas, Armco has the steels and the specific information you need for^ economical materials selection.

Armco 9% Nickel Steels provide toughness, strength and ductility at temperatures down to -320 F (ASTM A 353 or A 553 Grade A). But they are just two of the Armco steels for use in LNG process vessels and storage tanks.

A recent addition to this family is Armco CRYONIC 5 Steel. Basically, it's a 5% nickel steel with tough- ness properties for all LNG applications. The ASME Boiler and Pressure Vessel Code includes the addition of

SA 645 with an allowable stress of 23.7 ksi at temperatures 150 F and below. But the real advantage of CRYONIC 5 is its lower cost (approximately 20%) due to the reduced nickel content. CRYONIC 5 is designed specifically for containment of ethylene at -155 F and liquefied natural gas at -258.6 F.

Because Armco 9% Nickel Steel and CRYONIC 5 Steel are both designed for LNG containment, either land- based vessels, tanks or ocean-going tankers, you can be assured of an economical selection of steel.
