How is steel named?
Carbon steel Carbon steels and alloy steels are designated a four digit number, whereby the first digit indicates the main alloying element(s), the second digit indicates tg (top grade) element(s), and the last two digits indicate the amount of carbon, in hundredths of a percent (basis points) by weight.
What does EN stand for in European standards?
European Standards (abbreviated EN, from the German name Europäische Norm (“European Norm”)) are technical standards drafted and maintained by CEN (European Committee for Standardization), CENELEC (European Committee for Electrotechnical Standardization) and ETSI (European Telecommunications Standards Institute).
Why do some steels have five digit names?
A four-digit number series designates carbon and alloying steels according to the types and classes. This system has been expanded, and in some cases five digits are used to designate certain alloy steels.
When was steel invented in Europe?
13th century BC – The earliest evidence of steel production can be traced back to early blacksmiths in the 13th century who discovered that iron become harder, stronger and more durable when carbon was introduced after being left in coal furnaces.
Is the en 10027 designation system for steels easy to use?
Once you know how it works it is easy to use. Structural and pressure vessel steels have a standardised naming convention and this is laid out in EN 10027 Designation System for Steels. Whilst both are similar they are each subtly different and it is important to know what all the components of a steel name mean
What do the letters in steel names mean?
DIN And EN Steel Standards Naming Conventions Steel names preceded with X mean it is a high alloy steel, the X itself only notifies the reader of the name that the numbers behind the composition are nominal percentages. If the name is not preceded with an X it means the numbers are modified with a multiplier.

What is the BS EN standard for steel?
BS EN STANDARDS USED • BS EN 10079:1992 : It is a Reference standard which defines steel products based on their physical properties a) Their shape and dimensions b) Their appearance and surface condition • BS EN 10027-1:1992:The steel grade names consist of alpha numerical characters and define two main designation systems. 5.
