S355J2N

S355J2+N As Per EN 10025: 2004 Specification Steel Plate

S355 J2+N offers high yield and tensile strength with a minimum yield strength of 355 N/mm² , a structural steel which is widely used in engineering and construction industries, & which can be supplied with a variety of treatments and test options to ensure that it is a highly usable steel in your various projects.

S355J2+N is welder-friendly, low carbon, high tensile strength structural steel, can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process and supplied in a normalized or controlled rolling condition.

S355J2+N and S355J2G3 are the same steel grades as both grades delivery condition are normalized. G3 and N stand for normalized.

 Application Of S355 Plates

Suitable for wide variety of structural application for instance: freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators, forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures, offshore structures, shipbuilding, fans, pumps, lifting equipments and port equipments.


Ultrasonic Testing

If specified at the time of order, ultrasonic testing is carried out.

Surface Inspection

All plates manufactured through the plate mill are inspected and defects repaired in accordance with EN 10163-2: 1991 Class A Subclass 1, unless otherwise agreed.

Certification

All material described in this data sheet is supplied with analysis and test certificates.

Grinding 

Surface Grinding and Edge Grinding is available on all flame cut plates. This is carried out on a lumsden grinding rotary reciprocating table machines. After being Flamecut pieces can be ground to clean up or cut plates which can Lumsden ground to size on thickness to an tolerance of +/-0.25mm

A tighter tolerance may be possible, please provide your required tolerances when enquiring with our sales team.


Heat Treatment

S355 is not ideally suited to hardening, though it can be subjected to limited heat treatment process such as case hardening. If hardening S355 heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component.

Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of carbon steel grades.
