DIN933 DIN931 Hastelloy C276 threaded stud bolt manufacturer PTFE coated bolt

The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

HASTELLOY(r) C276 is normally used in solution treated conditions. This alloy is soaked at 1121¡ãC (2050¡ãF) and then rapidly quenched.

HASTELLOY(r) C276 can be welded by common welding methods. Excessive heat input should be avoided during welding. For corrosive applications, this alloy can be used in the “as-welded” condition without further heat treatment.
