1.1106
P355NL2; EStE355
high-quality steel; non-alloyed; pressure vessel steel
-
The material 1.1106 or P355NL2 is a pressure vessel steel with good cold toughness. It is very similar to the material P355NL1 and differs from it by an even closer tolerance of the alloying elements phosphorus and sulfur and even higher minimum values in the notched bar impact test in all low-temperature ranges.
