Working with 1.4854 FORGED-SA
Is 1.4854 easy to machine?
Machines like a hot-work superalloy: rigid setups, sharp positive-rake carbide, low speed (~15–25 m/min HSS-free), heavy positive feed to cut under the work-hardened layer, and flood coolant.
Can 1.4854 be welded?
Readily welded by GTAW/GMAW/SMAW with matching 353 MA filler or Ni-base (e.g. ERNiCr-3/ERNiCrCoMo-1); low heat input, no preheat, no PWHT required for thin sections.
Can 1.4854 be formed, bent or molded?
Cold forms well but needs ~50% higher press loads than 304 and generous bend radii; hot work at 1150–950 °C followed by solution anneal at ~1150 °C with rapid cooling.
What surface finishes work on 1.4854?
Pickle/passivate after hot work to remove Cr-depleted scale; mechanical grinding and polishing are effective, no anodizing or plating normally used.

1.4854 FORGED-SA — frequently asked
What is 1.4854 FORGED-SA used for?
1.4854 FORGED-SA is typically used for furnace rollers, radiant tubes, kiln fittings, high-temperature fasteners and combustion chambers. In short: 1150 °C service austenitic; cerium-stabilised oxidation resistance; carburization-resistant furnace alloy.
What is the yield strength of 1.4854 FORGED-SA?
1.4854 FORGED-SA has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 690 MPa (100 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4854 FORGED-SA easy to machine?
Not especially — machinability is rated poor (27/100, worse than 83% of stainless steel grades). Machines like a hot-work superalloy: rigid setups, sharp positive-rake carbide, low speed (~15–25 m/min HSS-free), heavy positive feed to cut under the work-hardened layer, and flood coolant.
Can 1.4854 FORGED-SA be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/SMAW with matching 353 MA filler or Ni-base (e.g. ERNiCr-3/ERNiCrCoMo-1); low heat input, no preheat, no PWHT required for thin sections.
What surface finishes work on 1.4854 FORGED-SA?
Pickle/passivate after hot work to remove Cr-depleted scale; mechanical grinding and polishing are effective, no anodizing or plating normally used.
Can 1.4854 FORGED-SA be formed, bent or molded?
Cold forms well but needs ~50% higher press loads than 304 and generous bend radii; hot work at 1150–950 °C followed by solution anneal at ~1150 °C with rapid cooling.
What is the maximum service temperature of 1.4854 FORGED-SA?
1.4854 FORGED-SA is rated for continuous use to about 1,150°C (2,102 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4854-SA and 1.4854-CD?
SA is the default condition — standard stocked condition for plate and most product forms — maximum ductility and oxidation performance. CD: choose for close tolerance small-diameter bar and higher room-temperature strength; strength gain is lost above ~700 °C. Yield strength is 330 MPa in SA versus 570 MPa in CD.
