(plate, sheet, strip, and wide flats) made of unalloyed and alloyed ferritic steels used in pressure vessel fabrication

As the AD 2000 Code is a copyrighted set of technical rules, "free" official copies are generally not available. However, you can find overviews and historical versions for research through the following types of platforms:

Unalloyed and low-alloy steels (plates, strips, pipes, and forgings).

: Applicable for working temperatures down to -10∘Cnegative 10 raised to the composed with power C

Without access to Merkblatt W1, a manufacturer cannot properly qualify steel plates for a pressure vessel intended for the EU market. Hence, the demand for a free version is high, especially among small workshops, freelancers, and engineering students.

However, "free" does not have to mean "illegal." There are several legitimate gray areas and practical alternatives to access the information within W1 for free or at a low cost.
