S32760 ASTM A182 F55 Weld Neck Flange

 Super Duplex S32760 / A182 F55 /1.4501

S32760 is a super duplex stainless steel with a 50:50 austenite, ferrite microstructure. The material combines high mechanical strength and good ductility with excellent corrosion resistance in a variety of environments.

This material is generally supplied in the annealed condition giving yield strength in excess of 550Mpa, this material cannot be hardened by heat treatment but stronger surface strength can be achieved by cold working.

Typical applications include many components for the chemical processing, marine, oil and gas, pollution control and food industries amongst others.
