S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The EN S355M steel plate, steel Grade S355NL making process shall according to EN10025-1.

Different form EN S355M steel plate, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.
Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
The high strength EN S355M steel plate low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you.
