ASTM A553 Type 2
ASTM A553 Type 2 covers 8% nickel alloy steel plates that are used in the fabrication of cryogenic pressure vessels. This material is capable of operating at temperatures as low as -170oC, and has high levels of strength and weldability.
ASTM A553 Type 2 8% nickel is a martensitic steel when it is quenched or tempered up to thicknesses as high as 100 mm. It is a unique martensite as it isn’t brittle or hard, but it is strong and tough which makes it easily to fabricate into pressure vessels.
Our range of ASTM A553 Type 2 8% nickel steels are perfect for containing or transporting cryogenic gases, such as nitrogen, oxygen, and argon.
