Steel P355NL2-N vs P355NL2 N t50-100

Steel · P355NL2 temper comparison

P355NL2-N and P355NL2 N t50-100 are two conditions of the same steel grade, P355NL2: N (normalized) versus N t50-100 (n). The chemistry is identical, so every difference below comes from the condition. P355NL2-N is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 350 MPa (50.8 ksi) for P355NL2 N t50-100, about 10% more.
