An austenitic round bar made of grade 904l which has a smooth surface and also do not require high strength works is 904l stainless steel round bar. This round bar also comes with an added property of excellent resistance to wide range of corrosive environments.
Grade 904l round bars have melting point range of 2371-2534oF. They also exhibit tensile strength of 490 Mpa, with the minimum yield strength of 220 Mpa and elongation of 36%. It has chemical composition comprising 23-28% nickel, 19-23% chromium, 4-5% molybdenum, 1-2% copper and 2% manganese.
Yes, we can solution-treat stainless steel 904L rod in the temperature range of 1994-2147oF. This process is also accompanied or associated with rapid cooling. Adding to this, if we want to enhance or harden these grades, thermal treatment can be performed too.

Not only stainless steel 904L rod provides resistance to corrosion to wide range of environments, it also offers excellent resistance to seawater and chloride attacks. This excellent resistance capacity comes because of the high amounts of nickel in their compositions.
In addition to this, presence of copper also ensures that this rod provides resistance to sulphuric acids and also, in mild and aggressive conditions, it also offers resistance to reducing agents.
These are some of the reasons why they do not rust and last for a long period of time and are widely demanded for wiring in electrostatic precipitators, industries processing pulp and papers, gas scrubbing plants, and oil refinery components, where maintenance factor is also reduced as this rod requires minimum maintenance.

904l stainless steel bar come up with the surface finish, such as hot rolled, cold rolled, polished and mirror finished. Because they have molecular structure and added smooth finish, they are also known by the name of bright bars.
Since this bar comprises varied composition of nickel, molybdenum and chromium, they exhibit excellent mechanical properties, along with high durability and strength. They also yield excellent weldability characteristics. Hence these are the reasons it is an ideal use case in marine environments.
While purchasing ASTM B649 UNS N08904 hex bar you must firstly understand what are the properties that it delivers and does it satisfy your needs and standards. The quantity factor for this bar depends entirely upon the availability and the demanded quantity Irrespective of the quantity, be it small or in bulk amounts, we at regentsteel.com would help you provide reasonable pricing that can suffice your needs.
