UNS S31803 Round Bar

ASTM A276 F51 Rod manufacturer and Suppliers in India


Bars are long metal objects that come in different shapes such as Round, square and hexagonal shapes. Their standard diameters range between 0.25 - 24 inch and they are formed out of different elements such as Stainless steel, Titanium, Copper, and Iron.

UNS S31803 round bar which has equivalent Werstoff No 1.4462 is formed of duplex stainless steel which comprises austenite and ferrite in equal ratio. It has a moderate density of 7.805 g/cm3 and melting point ranges between 1420 - 1465 degrees Celsius. Duplex Steel UNS S31803 Bars are known for their high strength and toughness as their tensile strength is 621 MPa and density is 7.82 g/cm3. The bar shapes get changed as per industry requirements such as ASTM A479 UNS S31803 Hex Bar.

These are hexagonal in shape and are heated uniformly in the range of 1750 - 2250 Fahrenheit. Their ISO Tolerance is in the range of h8 to h11.

F51 round bar is formed of duplex Stainless steel and combines good mechanical strength with corrosion resistive properties. It cannot be hardened by heat but can be made stronger by cold working. Standardized ASTM A276 F51 Duplex Round Bar is made up of 21% chromium and 4.5% nickel and is an ISO 9001:2008 certified product having tensile strength up to 105 N/mm2 and Hardness Brinell between 170-255. UNS s31803 f51 Rods provide high performance under high temperatures, typically more than 300-degree Celsius, and can work between 1020-1100 Celsius. It is designed to take the stress of up to 23.1 ksi at 600 Fahrenheit.

Steel grade S31803 bars have high iron content between 63-70% and the rest is Chromium, Nickel, and Molybdenum. Due to this, it has high resistance to corrosion and against chloride-rich solutions, thus they are used in chemical industries, water desalination plants.
