Stainless Steel Round Bar is sometimes also known as bright bar, or solid bar. Because it’s made from stainless steel, which contains chromium, this product enjoys excellent corrosion resistance. Those grades with higher alloy content have the added benefit of also being highly resistant to acids, chlorine, and alkaline solutions. These properties, coupled with inherent strength and longevity, help make stainless steel round bar popular in the transport, construction, automotive and petrochemical industries, among others.

Round bar can be manufactured using either cold finish or hot finish processes, and is generally available in a number of different grades and diameters, making it suitable for use in many varied applications.

Grade 303 – This is generally considered the best grade for machining, so is naturally popular in projects where extensive machining is required.

Grade 304 – This is the standard “18/8” stainless, and has excellent forming and welding characteristics. Grade 304L is the low carbon version of 304, and does not need post-weld annealing. This makes it ideal for using in heavy gauge components.

Grade 316 – Second only to 304 amongst the austenitic stainless steels, this is the standard molybdenum-bearing stainless steel, which means it has better overall corrosion resistance than 304, especially when it comes to pitting and crevice corrosion common in chloride environments. It has excellent forming and welding characteristics.

Grade 420 – this contains a minimum of 12 percent chromium, and can be hardened by quench-and-temper heat treatment. Its best corrosion resistance is achieved when the metal is hardened and then surface ground or polished.

Grade 431 – this is a nickel-bearing grade and has the best corrosion resistance properties of all the martensitic grades. It has excellent tensile and torque strength, and is very tough, making it perfect for shafting and bolt applications.
