S355N high strength steel plate is a European standard low alloy high strength structural steel with excellent mechanical properties and a wide range of applications.
S355N low alloy steel material can still maintain high impact toughness under low temperature conditions, such as excellent impact toughness at -40℃, which enables it to maintain stable performance in harsh environments.
S355N high yield strength steel plate has good weldability and is suitable for a variety of welding processes. At the same time, S355N high strength low alloy steel can also be cut and processed by a variety of methods, such as flame cutting, laser cutting, etc., to meet the needs of different customers.
