S420NL Steel Introduction
S420NL belongs to hot rolled products of structural steels, delivered in normalized or normalized rolled conditions. S420NL is weldable fine grain structural steel, generally used in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.
Regarding to the steel number of S420NL:
S standards for structural steel
420 indicates the minimum specified yield strength for thickness ≤ 16 mm expressed in MPa
N refers to delivery condition
L for the quality with specified minimum values of impact energy at temperatures not lower than -50℃.
S420NL Steel Delivery state: Normalized/ Normalized rolled
S420NL Steel Application
S420NL is weldable fine grain structural steel, generally used in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.
Please refer to the flowing chemical analysis and mechanical properties to see whether it is suitable for your project.
