This must-have reference for all mechanical, civil and chemical engineers, material scientists and chemists working with steel or acidic media explains how to strengthen the corrosion resistance of steels as reaction, transport and storage devices against omnipresent and aggressive inorganic acids.

Practically all industries face the problem of corrosion – from the micro-scale of
components for the electronics industries to the macro-scale of those for the chemical
and construction industries. This explains why the overall costs of corrosion still
amount to about 2 to 4% of the gross national product of industrialised countries
despite the fact that billions of dollars have been spent on corrosion research during
the last few decades.
Much of this research was necessary due to the development of new technologies,
materials and products, but it is no secret that a considerable number of failures in
technology nowadays could, to a significant extent, be avoided if existing knowledge
were used properly. This fact is particularly true in the field of corrosion and corrosion
protection. Here, a wealth of information exists, but unfortunately in most
cases it is scattered over many different information sources. However, as far back
as 1953, an initiative was launched in Germany to compile an information system
from the existing knowledge of corrosion and to complement this information with
commentaries and interpretations by corrosion experts. The information system,
entitled “DECHEMA-WERKSTOFF-TABELLE” (DECHEMA Corrosion Data Sheets),
grew rapidly in size and content during the following years and soon became an
indispensable tool for all engineers and scientists dealing with corrosion problems.
This tool is still a living system today: it is continuously revised and updated by
corrosion experts and thus represents a unique source of information. Currently, it
comprises more than 12,000 pages with approximately 110,000 corrosion systems
(i.e., all relevant commercial materials and media), based on the evaluation of over
100,000 scientific and technical articles which are referenced in the database.
Increasing demand for an English version of the DECHEMA WERKSTOFFTABELLE
arose in the 1980’s; accordingly the first volume of the DECHEMA Corrosion
Handbook was published in 1987. This was a slightly condensed version of the
German edition and comprised 12 volumes. Before long, this handbook had spread
all over the world and become a standard tool in countless laboratories outside
Germany. The second edition of the DECHEMA Corrosion Handbook was published
in 2004. Together the two editions covered 24 volumes.
Water is commonly described either in terms of its nature, usage, or origin. The
implications in these descriptions range from being highly specific to very general.
The present handbook compiles new and updated information on the corrosion
behaviour of iron, nickel, zinc and their alloys in contact with the following water grades: drinking water, sea water, industrial and municipal waste water and high
purity water.
All water contains some dissolved oxygen and is therefore somewhat corrosive.
The rate of corrosion depends on many factors including the water’s pH, electrical
conductivity, oxygen concentration, and temperature. In addition to corrosion, metals
dissolve when the water is extremely low in dissolved salts and in the presence of
certain water-borne ions.
Understanding how to improve the corrosion resistance of iron, nickel, zinc and
their alloys used in construction, transport and storage vessels and structures
against this omnipresent chemical is crucial for all industries involved. This book is
therefore an indispensable tool for all mechanical, civil and chemical engineers,
material scientists and chemists working with these materials.
This handbook highlights the limitations of iron, nickel, zinc and their alloys in
various water grades and provides vital information on corrosion protection measures.
The chapters are arranged by the media leading to individual corrosion reactions,
and a vast number of alloys are presented in terms of their behaviour in these
media. The key information consists of quantitative data on corrosion rates coupled
with commentaries on the background and mechanisms of corrosion behind these
data, together with the dependencies on secondary parameters, such as flow-rate,
pH, temperature, etc. Where necessary this information is complemented by more
detailed annotations and by an immense number of references listed at the end of
each chapter.
An important feature of this handbook is that the data was compiled for industrial
use. Therefore, particularly for those working in industrial laboratories or for industrial
clients, the book will be an invaluable source of rapid information for day to day
problem solving. The handbook will have fulfilled its task if it helps to avoid the
failures and problems caused by corrosion simply by providing a comprehensive
source of information summarising the present state of the art. Last but not least, in
cases where this knowledge is applied, there is a good chance of decreasing the
costs of corrosion significantly.
Finally the editors would like to express their appreciation to Dr. Rick Durham
and Dr. Horst Massong for their admirable commitment and meticulous editing of
a work that is encyclopaedic in scope.
