Material number 1.0026: S195T
1.0026 is the European material number (Werkstoffnummer, EN 10027-2) for S195T, non-alloy steel for welded and threaded tubes (water, gas, sprinkler, GI pipe) specified in EN 10255.
Reading 1.0026 digit by digit
An EN 10027-2 number has the form 1.XXYY. The leading 1 marks it as steel. The pair 00 is the steel group, and for this number that group is base steels. The final pair 26 is a sequential count inside that group and carries no meaning of its own — 1.0026 is simply the 26th entry registered there.
The group digits are the useful part. Reading 00 tells you what kind of steel you are looking at before you know anything else about it, and the 5 other numbers from group 00 held here are listed below.
