UNS S32750 Round Bar

Astm A276 F53 Rod & Hex Bar manufacturer in India.


A round bar is a cylindrical metal bar having a 5mm to 450mm radius of length 2 to 6 meters. The bar and rods are available in hexagonal and square shapes as well. One such is, UNS S32750 round bar which is equivalent to Werkstoff NR 1.4410. It comes with a 10 to 100 mm diameter, the ultimate tensile strength of 750 ksi and can take minimum stress of 550 N/mm2.

Super Duplex UNS S32750 Bars have high resistance to corrosion fatigue and chlorine ions. These bars are heat-treated at 1100 degrees Celsius followed by water quenching. They come in different standards, one such is ASTM A479 UNS S32750 Hex Bar comes with different tolerance levels e.g. H8 - H12, K10 to K12 and has a high tensile strength of 730 MPa. These bars are used in the marine and petrochemical industries.

F53 round bar is a high alloy duplex stainless steel with austenitic and ferritic microstructure. They are used for applications flame hardening for surface hardness is required with the common standard of ASTM A182 F53. Another bar standard UNS S32750 F53 Rods has high fatigue strength of 450 MPa and an elastic modulus of 200 GPa. Further, it has a high melting point of about 1410 degrees Celsius. F53 is the common industry name for UNS S32750 stainless steel. Industries use ASTM A276 F55 Duplex Round Bar for its high mechanical strength and resistance to pitting and crevice corrosion. It has proof stress equivalent to 550 MPa and a 23% elongation rate. It has applications in power generation, heat exchangers, and seawater applications.

F53 or S32750 bars are duplex stainless steel but they use less tungsten than S32760 due to their specific requirement. These bars have the size in the range of 6mm to 120 mm and length varies from 100 to 600 mm.
