The storage of hydrogen-sulfides, which cause highly dangerous corrosive damages in pressure vessel materials by released hydrogen atoms, constitutes a great challenge for plant constructors.

To meet this challenge, thyssenkrupp Steel Europe has introduced a new steel grade to their usual pressure vessel steels and now offers sourgas resistant steels.

These new, so-called X-COR® steels may be delivered certified according to DIN EN 10028 as well as ASTM 516, or on demand with multiple certifications, as ASTM A516 Grade 60/65/70, P295H, P355NH/NL1/NL2 up to a plate thickness of 60 mm.

The mechanical properties meet the standards above, even after post weld heat treatment. The verification of mechanical properties is carried out in normalized state.

The sour gas resistance is tested in our own, certified testing laboratory and is guaranteed for the normalized, stress-relief heat treated state.

Steel for pressure vessels

thyssenkrupp Steel Europe offers cryogenic nickel steel for liquid gas vessels and pressure vessels as well as sourgas resistant pressure vessel steels.
