A duplex stainless steel round bar enquiry starts with the required UNS grade and the component drawing. S31803, S32205, S32304, S32750, S32101 and S32550 are the grade references associated with this bar; specify the exact designation when discussing a food-processing, water-treatment or chemical-processing project.
Match the duplex grade to the process
For a water-treatment component or a chemical-process part, state the operating environment before choosing a duplex round bar. Ask for the material documentation applicable to the proposed supply, and check the grade against the project specification rather than treating all six UNS references as interchangeable.
- Choose a round-bar diameter of 10, 20, 30, 50, 80, 100, 150 or 200 mm.
- Identify the required UNS designation, such as S31803 or S32205, in the enquiry.
- Provide the finished component dimensions alongside the selected bar diameter.
- Discuss the required cut length within the stated 15–9000 mm length range.
- Specify the intended duplex-bar surface condition and drawing tolerances.
From round stock to a defined component
The eight diameter selections make the starting section explicit, while the cut length still needs to match the duplex-bar order. For valve-related work or another machined component, include the drawing and ask which processing operations apply to that particular diameter, length and grade.
What to establish for food or chemical service
A duplex grade name alone does not establish approval for a food-contact component or suitability for every process medium. For a food-processing or chemical application, confirm the applicable material requirements, surface condition and service conditions before accepting the bar specification.
Send the UNS reference, diameter, cut length and intended process together so the duplex stainless steel round bar can be discussed as one defined requirement.
