These standard are the latest European standards for structural steel. hey replace BS 4360, EN 10025:1993, EN 10113:1993, EN 10155:1993 EN 10137:1996.

Steel Names according to EN 10027-1 in form of ....X(1) nnn(2) Xn (3) Xn(4).....Example S355J2G3

1)  X = Letter identifying use i.e S= Structural Steel, E = Engineering steel without requirements for toughness and weldability

2)   nnn = Number identifying minimum yield Strength(N/mm 2)

3)   Xn = Information on impact properties
Testing Temperature = 20 o C,   JR = 27Joule,   KR = 40Joule
Testing Temperature = 0 o C,   J0 = 27Joule ,   K0 =40Joule
Testing Temperature = -20 o C,   J2 = 27Joule,   K2 = 40Joule

4)   Xn = Symbols for special requirements
Deoxidation Method ...G1= Rimming Steel, G2 =Rimming Steel not permitted,
Delivery conditions...G3 = Normalised/ Normalised Rolled, G4 = Manufactures Discretion.
