Working with 1.4961
Is 1.4961 easy to machine?
Machines like 347/321 — gummy and strongly work hardening; use rigid setups, positive-rake sharp carbide, heavy constant feed and flood coolant, avoid dwelling.
Can 1.4961 be welded?
Readily welded by GTAW/GMAW/SMAW with matched Nb-stabilized filler (ER347/E347); no post-weld annealing needed, but keep heat input and interpass temperature low to limit hot cracking and use low-ferrite fillers for high-temperature service.
Can 1.4961 be formed, bent or molded?
Good cold formability with high springback and rapid work hardening; hot work at 1150–900 °C then solution anneal 1050–1120 °C and water quench.
1.4961 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

| Fe | balance |
What surface finishes work on 1.4961?
Pickle and passivate (ASTM A967) or electropolish after hot working/welding to restore the passive film; not anodizable; mechanical polishing to a mirror finish is straightforward.

1.4961 — frequently asked
What is 1.4961 used for?
1.4961 is typically used for high-temperature fasteners, furnace components, exhaust systems, heat-resistant structural parts and boiler fittings. In short: nb-stabilized 347-type grade; 700 °C service capability; no post-weld anneal needed.
What is the yield strength of 1.4961?
1.4961 has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 590 MPa (85.6 ksi) — weaker than 91% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is 1.4961 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Machines like 347/321 — gummy and strongly work hardening; use rigid setups, positive-rake sharp carbide, heavy constant feed and flood coolant, avoid dwelling.
Can 1.4961 be welded?
Yes — weldability is rated very good (75/100). Readily welded by GTAW/GMAW/SMAW with matched Nb-stabilized filler (ER347/E347); no post-weld annealing needed, but keep heat input and interpass temperature low to limit hot cracking and use low-ferrite fillers for high-temperature service.
What surface finishes work on 1.4961?
Pickle and passivate (ASTM A967) or electropolish after hot working/welding to restore the passive film; not anodizable; mechanical polishing to a mirror finish is straightforward.
Can 1.4961 be formed, bent or molded?
Good cold formability with high springback and rapid work hardening; hot work at 1150–900 °C then solution anneal 1050–1120 °C and water quench.
What is the maximum service temperature of 1.4961?
1.4961 is rated for continuous use to about 700°C (1,292 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4961-SA and 1.4961-CD?
SA is the default condition — standard supply condition for plate, bar and tube — maximum ductility, corrosion resistance and creep design values. CD: use where closer tolerances, better surface finish and higher room-temperature strength are needed than annealed bar. Yield strength is 250 MPa in SA versus 450 MPa in CD.
How much does 1.4961 cost?
1.4961 is a premium-cost stainless steel ($$$), cheaper than about 51% 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.
