Explanation of the BS EN 10027-1: 1992 Specifications

The latest European Standards incorporate numbers and letters which identify the properties of the various grades within the Standard. A typical Specification example might be:

NameDescription
BSindicates that this is a British Standard
ENindicates that it holds the status of a European Standard
10027indicates the number of the relevant Standard
Next is a letter denoting the type of steel. Followed by a number, being the characteristic Yield Strength in N/mm2 or the specified Minimum Tensile Strength in N/mm2.
GSteel Castings
SStructural Steels. The Number = minimum yield strength for smallest thickness.
PPressure Vessel Steels. The Number = minimum yield strength for smallest thickness.
LLinepipe Steels. The Number = minimum yield strength for smallest thickness.
EEngineering Steels. The Number = minimum yield strength for smallest thickness.
BSteels for Reinforcing Concrete. The Number = characteristic yield strength.
YSteels for prestressing concrete. The Number = minimum tensile strength.
RSteels for or in the form of Rails. The Number = minimum tensile strength.
HSteels for Cold Rolled Flat Products of high strength steels for Cold Forming. The Number = characteristic yield strength.
DFlat Products for Cold Forming (except H). Followed by:
Cfor Cold Rolled
Dfor Hot Rolled products for direct Cold Forming and
Xfor non specified rolled condition.
TTinmill Products.
MElectrical Steels.
JRIndicates that the Charpy Impact Test was conducted to 27 joules minimum at room temperature.
J0Indicates that the Impact Test was performed to 27 joules minimum at 0 °C.
J2Indicates that the Impact Test was performed to 27 joules minimum at -20 °C.
K2Indicates that the Impact Test was performed to 40 joules minimum at -20 °C.
G3Indicates delivery conditions are at the manufacturer’s discretion.
The last letter, if applicable:
HIndicates Hollow Section.
LIndicates qualities with specified minimum values of impact energy at a temp. of -50 °C
MIndicates Thermomechanically rolled feedstock material.
NIndicates Normalised or Normalised Rolled Feedstock material.
