Steel Names generally in accordance with EN 10027-1 in the form of ........X(note 1) nnn(note 2) Y (note 3) Y(note 4)....
Examples. P265GH, P275NL1, S355NL, S355ML
1) X = Letter identifying use i.e S= Structural Steel, P = Steel for Pressure purposes
2) nnn = Number identifying minimum yield Strength (N/mm 2)
3) Y = Letter identifying condition
N = Normalised S
G = Other Characteristic follows
M = Thermomechanically Rolled
4) Z identifies property information
H = Elevated Temperature Properties. Possible requirements for tensile test at high temperature.
L = Low temperature properties, Impact testing at -10 Deg. C
L1 = Low temperature properties, Impact testing at -50 Deg. C
L2 = Special low temperature properties, Impact testing at -50 Deg. With enhanced requirements
Tables identifying composition,yield strength and tensile strength at room temperature are provided on webpage BS-EN-10028 Steels
