EN 10025-3 S420N Steel Plates

‌

S420N low alloy steel material is a high strength low alloy steel plate, mainly used for manufacturing large welded structural parts such as pressure vessels.

 

S420N high strength plate follows the European standard EN 10025 and is usually delivered in normalized or normalized rolled state. GNEE can also deliver it after other heat treatments according to customer needs.

 

S420N high tensile steel plate has high strength and good toughness. It can maintain good toughness even at low temperatures and can be connected by a variety of welding methods.

 

In addition, S420N high strength steel plate also has a certain corrosion resistance. After proper anti-corrosion treatment, its corrosion resistance can be further improved, thereby extending its service life. ‌
