Why Choose Nickel Alloys Round Bar
Straightness and tolerance
Round bar is supplied to h9 / h11 tolerance with straightness within 1 mm per metre, ready for direct machining without pre-straightening.
Full-length traceability
Every bar is stencilled with heat number, grade and specification so the mill test certificate can be matched to the piece on your shop floor.
Cut to your length
Bandsaw cutting to ±1 mm on lengths from 100 mm upwards, so you pay for the metal you use rather than a full mill length.

Grade chemistry and mechanical properties supplied in nickel alloys round bar.
Chemical composition and mechanical properties are grade properties, not form properties — the same grade keeps the same chemistry whether it is supplied as sheet, plate or coil. The tables below list the specified limits for each grade we stock in nickel alloys round bar, tested and certified to ASTM B446 / B164 / B574 / B637. Values are weight percent (maximum unless a range is shown); mechanical values are minima in the annealed condition.
