Stainless Steel Nitronic 33 Special Alloys For Medical With Yield Strength 469MPa

Stainless steel Nitronic 33 (UNS S24000, XM-29) wire, strip, tube and bar for MRI scanner supports, fittings etc


1 PRODUCT

Stainless steel Nitronic 33 (UNS S24000, XM-29) for MRI scanner supports, fittings etc.

Nitronic 33 Stainless Steel is available in bar, rod, wire, forging billets, sheet, strip, foil, extrusions, seamless tubing, shape etc.


2 OVERVIEW

Nitronic 33 is a low nickel austenitic stainless steel having an annealed yield strength twice that of 304. Better resistance to stress corrosion cracking than 304. Low magnetic permeability even after severe cold working.


3 APPLICATION

Cryogenic tanks valves, piping, flanges, structural supports. Abrasion/Wear Resistance screens, racks, and wear plates. Electrical (low magnetic permeability) conduit shielding, MRI scanner supports, fittings, underground transmission risers and pipe and electronic support members. Process equipment, heat exchangers, pressure vessels and piping where 304 is borderline with respect to stress corrosion cracking.

8 MACHINING AND FORMING

Forging

Heat to 2000°F, soak to equalize, then heat to 2150°F and equalize prior to forging.

Annealing

Soak at 1900-2050°F, quench quickly in air or water.

Hardening

Hardening this alloy requires cold working. It will not harden with exposure to thermal treatment.
