ABSTRACT:
High-strength rods, useful in an acid enviroment, in which the H.sub.2 S partial pressure in gaseous phase may exceed 300 Pa or in which the H.sub.2 S content in liquid phase may have a corresponding equilibrium pressure and/or in which CO.sub.2 or other acidifying substances may be present are manufactured from cold-deformed carbon steel or cold-deformed low-alloyed steel. A preferred composition for the steel is:
