Hastelloy C276 Bars

In short: Hastelloy C276 bar to ASTM B574 is machined into agitator shafts, valve parts, fasteners and pump components for chemical service.

Calculated values for estimating; actual weights vary within tolerances.

Why this combination

Why Hastelloy C276 in bars

About 16% Mo, 15.5% Cr, 3.7% WExceptional resistance to reducing acids and chloridesUsable in the as-welded conditionPREN about 68–76

Agitator shafts and pump parts sit in the same aggressive media as the vessel; C276 bar keeps them intact.

Forged blanks for flanges and fittings are also cut from bar.

Specification

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
