For instance, in the presence of boiling magnesium chloride, an inorganic compound, the Inconel 625 forged bar demonstrates its superior resistance properties. The very high content of nickel in the chemical composition of Inconel 625 cold drawn bar makes it virtually resistant to chlorine related stress cracking. Usually, marine environments contain some chlorine salts which is encountered by the ASTM B446 UNS N06625 rod. As a high nickel containing component, the Inconel 625 square bar is able to battle not only pitting but also crevice corrosion in marine environments.
Very often the Inconel 625 hot rolled bar is a part of types of equipment that are used in marine based applications such as heat exchanger, fasteners, and cable sheathing. The Inconel 625 hex bar also has good weldable properties. Hence, welding the UNS N06625 rod in submarines or in maritime pieces of equipment make it a very good choice as they are not easily corroded as stainless steels. Further, the Inconel 625 flat bar is easily joined to other components, thereby securing a unique place in marine engineering purposes. In fact, the Inconel 625 rod exhibits good fatigue strength in addition to having exceptional mechanical properties.
Inconel 625 Round Bar is produced by many manufacturers in India from 0.30" to 7.0 inch according to AMS 5666 and ASTM B446, If you are looking for other size can be produced but it will higher 20% more than standard sizes and also require minimum quantity of 100 KG.

ASTM B446 UNS N06625 round bar features and types
The B446 or the Alloy 625 material is used to produce different products such as bars, sheets, strips, pipes, tubes and bolts and nuts. The round bar is one of the most used types. There are different types of round bars according to the manufacturing and finishing. There are cold drawn, hot rolled, annealed and heat treated round bars according to the production types. The finishes differ as black, bright, electropolished, galvanized, painted and coated. Depending on the need of the applications, these different production methods and finishes are chosen. All of these types of round bars have high corrosion resistance and temperature resistance properties.
