Why this combination

Why Inconel 625 in bars

High strength without age hardeningPREN > 50: excellent pitting and crevice resistanceImmune to chloride SCCGrade 1 (annealed) and Grade 2 (solution-annealed) conditions

Valve stems and subsea fasteners need strength and seawater resistance; 625 bar is a standard choice.

Bar for forgings is often ultrasonically tested.

Specification

How to specify Inconel 625 bars

Round bars about 3 – 500 mm diameter; hex 6 – 100 mm A/F; square and flat sections to order; lengths 3 – 6 m random or cut to size
