Material number 1.0226: DX51D
1.0226 is the European material number (Werkstoffnummer, EN 10027-2) for DX51D, hot-dip coated low-carbon steel for bending and profiling specified in EN 10346.
Reading 1.0226 digit by digit
An EN 10027-2 number has the form 1.XXYY. The leading 1 marks it as steel. The pair 02 is the steel group, and for this number that group is other structural steels. The final pair 26 is a sequential count inside that group and carries no meaning of its own — 1.0226 is simply the 26th entry registered there.
The group digits are the useful part. Reading 02 tells you what kind of steel you are looking at before you know anything else about it, and the 2 other numbers from group 02 held here are listed below.
