Working with N08332
Is N08332 easy to machine?
Work-hardens rapidly and is gummy — use rigid setups, positive-rake carbide, heavy feeds with no dwell, low-to-moderate speeds (~20–35 m/min) and copious sulfur-free coolant.
Can N08332 be welded?
Readily welded by GTAW/GMAW/SMAW with matching 330 or higher-Ni filler; keep interpass temperature low, avoid heavy restraint and sulfur contamination to prevent hot cracking.
Can N08332 be formed, bent or molded?
Very ductile when annealed — good for deep drawing, spinning and roll forming, but requires ~50 % more power than 304 and intermediate anneals for severe work.

What surface finishes work on N08332?
Pickle or bead-blast plus passivation after hot work; not anodizable — electropolishing or mechanical polishing gives the best high-temperature surface.

N08332 — frequently asked
What is N08332 used for?
N08332 is typically used for cryogenic vessels and piping, furnace and heat-treat fixtures, carburizing/heat-resistant components and petrochemical process equipment. In short: cryogenic to 1100 °C service; controlled-chemistry Alloy 330; high-nickel carburization resistance.
What is the yield strength of N08332?
N08332 has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 585 MPa (84.8 ksi) — weaker than 91% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is N08332 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% of stainless steel grades). Work-hardens rapidly and is gummy — use rigid setups, positive-rake carbide, heavy feeds with no dwell, low-to-moderate speeds (~20–35 m/min) and copious sulfur-free coolant.
Can N08332 be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/SMAW with matching 330 or higher-Ni filler; keep interpass temperature low, avoid heavy restraint and sulfur contamination to prevent hot cracking.
What surface finishes work on N08332?
Pickle or bead-blast plus passivation after hot work; not anodizable — electropolishing or mechanical polishing gives the best high-temperature surface.
Can N08332 be formed, bent or molded?
Very ductile when annealed — good for deep drawing, spinning and roll forming, but requires ~50 % more power than 304 and intermediate anneals for severe work.
What is the maximum service temperature of N08332?
N08332 is rated for continuous use to about 1,100°C (2,012 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between N08332 Annealed and N08332-CD?
Annealed is the default condition — standard stocked condition for plate, sheet, tube and welded fabrication; best ductility and toughness for high-temperature and cryogenic service. CD: higher strength, closer tolerance bar for machined fixtures, pins and studs where extra yield strength is useful below ~600 °C. Yield strength is 250 MPa in Annealed versus 550 MPa in CD.
How much does N08332 cost?
N08332 is a high-cost stainless steel ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
