Alloy 201 Elbow Manufacturing Process

Each fitting from a Nickel 201 Seamless Pipe Fittings lot follows these stages


1

Raw Material Selection

Nickel 201 pipe or plate is chosen against the UNS N02201 chemistry limits.

Heat checked
2

Cutting and Blanking

Pipe lengths or plate blanks are cut to the size needed for each fitting shape.

Sized to drawing
3

Hot or Cold Forming

Elbows, tees, reducers and caps are pushed, pressed or bent into their final form.

Shaping
4

Annealing

Heat treatment softens the metal and restores ductility lost during forming.

Annealed temper
5

Cleaning and Finishing

Surface scale is removed, then ends are machined and bevelled for buttwelding.

Mill finish
6

Marking and Packing

Heat number, grade and size are marked, then fittings are case packed for dispatch.

Heat traceable
