EN 10028:3 P355NL1 and P355NL2. About EN 10028:3 Pressure Vessel Steel Plate Plates to EN 10028:3 are widely specified in the manufacturing of pressure vessels throughout Europe. The standard is regularly seen in other parts of the world where equipment has been originally designed by a European company.
want to select the E 7018G (Esab) for welding the material P355NL2 .already we weld this material with 8016C1 (KOBE) but our client need some evidence for example somewhere PQR result to allow to use 7018G. I checked all properties & I can use .
P355NL1 steel and P355NL2 steel application : As steel for boilers and pressure vessels, P355NL1 steel and P355NL2 steel are mainly used in manufacture of petroleum, chemical, gas separation and shipping containers, or other similar devices, such as tower vessel, heat exchanger, storage tank, tank cars etc.
The steel grades P275NH - P355NL2 are delivered in a condition obtained by normalized rolling. The steel grades P355M - P460ML2 are delivered in a thermomechanically rolled condition. The provisions of DIN EN 10028-2 and -5 shall apply for delivery and inspection.
Among welding filler metals, H4 and H8 are common designations that indicate the filler metal contains low levels of diffusible hydrogen. The numeral in the designator signifies the amount of hydrogen, in milliliters, for each 100-gram amount of weld metal.
Post weld heat treatment (PWHT) refers to heat treatment applied to a material after welding. It is often used to improve the properties of the weldment.

Worldwide Welding Consumables. Metrode offers one of the largest ranges of alloyed welding consumables available from a single source. The products range from those suitable for low alloy steels, through numerous diverse steels, to those matching the performance of nickel-based alloys.
shop conditions. Prior to welding, however, it should be ensured that the grooves to be welded are dry and clean. For storage and drying of welding consumables, follow the manufacturers instructions. When welding high strength steels, it should be noticed that the filler metal may be clearly more alloyed and Welding. General
P355NL2 is a weldable, fine grained, normalised steel plate for high stressed welded constructions in constructional steelwork, hydraulic steelwork, bridge building, mechanical engineering, shipbuilding,
The welding techniques of pressure vessel steel P355NH P355NH steel is weldable fine-grain structural steel for pressure vessels, which is characterized by a minimum yield strength of 275-460 N/mm2.It is the unique mechanical properties that make P355NH steel possess good welding property.
P355NH. A pressure vessel steel grade with good weldability and high resistance to brittle cracking, P355NH is used by the world's fabricators for the manufacture of pressure vessel tanks for the storage of pressurised gases.
P355NL2 steel is characterised by good weldability and high resistance to brittle cracking. These types are used above all for manufacturing vessels for pressurised gas (LPG, butane and propane tanks), pressure vessels, parts for steam boilers, pressure piping, compressors, etc.

The steel grades P275NH-P355NL2 are delivered in a condition obtained by nor-malised rolling. The steels grades P355M-P460ML2 are delivered in a thermome-chanically-rolled condition. The provisions of EN 0028-2 and -5 shall apply for de-livery and inspection.
P355 boiler plate to EN10028-2 is a fine grained steel for used in pressure vessels, heat exchangers and reactors.. P355 is one of our most popular pressure vessel steels. . This is because our large steel stock of P355 is characterised by a high overall tonnage, large availability of plate dimensions in each thickness and the high quality of the steel we supp
To reduce the number of welding procedures to be qualified for production applications, codes and standards give provisions for a particular parent material and filler materials to cover a range of other materials considered to have similar weldability (ie to be affected by welding in a similar manner) or to require similar skills for p355nl2 welding

Solid welding wire for S355 - St52-3 steels S355 is a standard type of carbon steel with a yield strength of 355 N/mm2, practically all welding consumables do offer a yield strength far above and this type has no welding restrictions or the material has to be really thick.
portant is the proper choice of welding process, welding method and arc energy. Proper impact strength of the weld can be achieved by any common welding process provided that arc energy is kept within the limits recom-mended for the steel in question. Selecting the welding consumables Welding consumables for hot rolled steel are chosen
Welded ERW steel pipes and cylinders are utilized in different building purposes, fencing, framework, line funnels and so forth. These channels are exceptionally sturdy, dependable, erosion safe and have high quality. Welded pipe is accessible with square closures or sloped for welding, strung and coupled and victaulic notched.
