Why this combination

Why Inconel 600 in tubes

≥ 72% nickel: immune to chloride SCCOxidation resistance to about 1,100 °CGood resistance to caustic alkalisNon-magnetic, readily fabricated and welded

Thermocouple sheaths and furnace tubes rely on 600's oxidation resistance at high temperature.

Exchanger tube in chloride service at temperature benefits from its resistance to stress corrosion cracking.

Specification

How to specify Inconel 600 tubes

OD 3 mm to about 127 mm (¼" to 5") typical, wall 0.5 mm to 12 mm; BWG or mm; straight lengths up to about 30 m, U-bent to drawing
