Stainless Steel Bar Alloys
Our inventory of stainless steel bar products includes 303 stainless steel bar, 304 stainless steel bar, and 316 stainless steel bar. For more grade and detailed information, feel free to contact with us.
Stainless steel can be used for environments or applications that require chlorine or alkaline exposure
Stainless steel can withstand highly acidic environments
Round bar is used for a wide range of industrial uses, including structural applications as well as industrial shafts.
Stainless steel according to the use of processing method is divided into: pressure processing steel and cutting steel; According to the characteristics of tissue, it can be divided into five types: austenite type, austenite - ferrite type, ferrite type, Martensite type and precipitation-hardening type.
303 Stainless Steel Round Bar
Ideal for automated machining applications, 303 stainless steel round bar is available with an annealed cold finish. Known for its machinability, the inclusion of sulfur lowers the corrosion resistance when compared to other stainless steel grades.
Used for machining applications
304 Stainless Steel Round Bar
As a versatile stainless steel alloy, 304 stainless steel round bar is used widely for commercial and industrial applications. Easily weldable and fabricated, it also offers good corrosion resistance. 304 SS is a heat-resistant alloy with good formability.
Ideal for heavy gauge parts or components
316 Stainless Steel Round Bar
With a higher molybdenum content than alloy 304, 316 stainless steel round bar is well suited for highly corrosive environments such as marine or outdoor applications. Easily formable and weldable, 316 stainless steel round bar is suitable for chemical processing and food prep equipment.
Suitable for medical instruments due to its hygienic and non-reactive properties
Applications for SS Round Bar
Stainless steel round bar can also be used for the following applications:
Railings
Beams
Handles
Braces
Shafts
Fasteners
While your application requirements will determine which metal is best suited for your needs, stainless steel round bar is often a great substitute for carbon steel. It offers better corrosion resistance and surface finishes.
Finishing Options
Common stainless steel finishing options include:
Mill Finish (2B)
Brushed
Mirror
Bright Annealed
