Allgemeine Produktbeschreibung

Normalized pressure vessel steel heavy plate dual certified to structural steel.

SSAB Multisteel PES is hot rolled structural steel for general pressure equipment steel constructions. PES = Pressure European Structural (meets the European standard).

Exceeding the requirements of several standard steel grades, SSAB Multisteel PES is a versatile pressure vessel steel for fabricated pressure equipment made of weldable fine grain steels. Formability and highly consistent quality guarantee fast, uninterrupted production, generating clear savings in the costs of material management. Certification also to structural steel according to EN 10025-2 gives more possibilities to use in several applications.

SSAB Multisteel PES exceeds several steel standards and is available as four steel grades: SSAB Multisteel PES, P355N, P355NH and P355NL2 according to EN 10028-3 and furthermore S355K2+N according to EN 10025-2.

SSAB Multisteel PES covers steel grades in four different qualities:

1) Room temperature quality (P355N)

2) Elevated temperature quality (P355NH)

3) Special low temperature quality (P355NL2)

4) Structural quality (S355K2+N)

5) SSAB Multisteel PES (all together)

PED certificate:

Pressure vessel steel grades recognized by standard EN 10028 are mainly delivered with the inspection certificate 3.1. Directive 2014/68/EU (PED) requires the manufacturer’s quality assurance system to be approved by an external accredited authority (Notified Body).

SSAB Europe Oy Raahe Works holds the PED – approval from DNV.

SSAB Raahe Works is authorized to use PED certificate for pressure equipment steels according to EN 10028-3 based on EN 10028-1.

Abmessungsbereich

SSAB Multisteel PES is available in thickness of 5.00 – 150.00 mm.

Verarbeitung und andere Empfehlungen

Welding:

Weldability is excellent with all welding processes. Increased working temperature requirements are less than those of the corresponding strength grades of standard steels. This means easier welding and cost savings under both workshop and site welding conditions.

Needed working temperatures for thick plates please consult SSAB Tech Support.

Forming:

SSAB Multisteel offers better formability properties than standard steels. Successful forming requires that the manufacturer uses good workshop techniques. Worn tools, poor lubrication, scratches on the surface of the steel as well as edge burrs will all reduce forming quality.

Guaranteed minimum bending radius for all directions is 2 x t up to 30 mm thick plate where t = plate thickness.

Heat treatment:

Recommendations for stress relieving and normalizing.

Stress relieving 550 – 600°C (target 580°C)

2 minutes/millimeter of thickness, however, 30 minutes minimum. Slow cooling in the furnace.

Normalizing 900 – 940°C (target 920°C)

1 minute/millimeter of thickness, however, 20 minutes minimum. Cooling in free air.
