|---|---|---|---|---|---|---|
Forged bar/ring, solution annealed | For furnace rolls, hangers, grate bars and machined fittings needing large section sizes. | 250 | 580 | 35 | 165 HB | 1.7 % IACS |
Hot finished seamless tube, solution annealed and pickled | Choose for superheater, reheater and furnace tubing in the usual hot-finished sizes to EN 10216-2 / EN 10095. | 255 | 590 | 40 | 170 HB | 1.7 % IACS |
SADefault Solution annealed | Standard delivery condition for tube, plate and bar: maximum ductility, homogeneous austenite with Nb carbides in solution/finely dispersed. | 260 | 600 | 40 | 170 HB | 1.7 % IACS |
Cold drawn then solution annealed | Use where tight dimensional tolerance and smooth bore are needed with fully annealed properties. | 270 | 610 | 38 | 175 HB | 1.7 % IACS |
Cold worked | Only for room-temperature strength or spring-like stiffness in small sections; not for creep service, since cold work is lost above ~600 °C. | 550 | 800 | 20 | 24 HRC | 1.7 % IACS |

What is 1.4877?
EN 1.4877 (X6NiCrNbCe32-27) is a niobium- and cerium-stabilised 32Ni-27Cr austenitic heat-resistant alloy engineered for high-temperature strength and carburisation resistance up to about 1100 °C. It is supplied as solution-annealed plate, bar, forgings, hot-finished and cold-drawn product with 260 MPa yield, 600 MPa tensile, 40% elongation and about 170 HB (86 HRB), and is chosen where 800H-class alloys run short on carburisation life. The high nickel content makes it costly and difficult to machine (score 25); Alloy 800H / 1.4876 is the cheaper option for milder furnace service. 1.4877 has a density of 7.9 g/cm³ (0.285 lb/in³), heavier than 68% of stainless steel grades. It melts at 1,340°C (2,444 °F). 1.4877 has a yield strength of 260 MPa (37.7 ksi) and a tensile strength of 600 MPa (87 ksi) — weaker than 84% of stainless steel grades. Elongation at break is 40% and the elastic modulus is 195 GPa (28.3 Msi).

Working with 1.4877
Is 1.4877 easy to machine?
Machine like Alloy 800H/803: rigid setups, sharp positive-rake carbide, low speed (20–40 m/min) with heavy constant feed and copious coolant to avoid work-hardened glaze.
Can 1.4877 be welded?
Weldable by GTAW/SMAW/GMAW with Ni-base or matching high-Ni filler (e.g. ERNiCr-3 / Alloy 82 type); keep heat input low, no preheat, interpass below ~150 °C, avoid excessive dilution to limit hot cracking.
Can 1.4877 be formed, bent or molded?
Hot work at 1150–950 °C then solution anneal; cold forming is possible but the alloy work-hardens rapidly so allow extra power, generous radii and intermediate annealing at 1050–1120 °C.

1.4877 — frequently asked
What is 1.4877 used for?
1.4877 is typically used for furnace muffles, ethylene cracking components and high-temperature fasteners. In short: top carburisation resistance; nb/Ce-stabilised for creep strength; above 800H in service life.
What is the yield strength of 1.4877?
1.4877 has a typical yield strength of 260 MPa (37.7 ksi) and a tensile strength of 600 MPa (87 ksi) — weaker than 84% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1.4877 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 88% of stainless steel grades). Machine like Alloy 800H/803: rigid setups, sharp positive-rake carbide, low speed (20–40 m/min) with heavy constant feed and copious coolant to avoid work-hardened glaze.
Can 1.4877 be welded?
Yes — weldability is rated good (68/100). Weldable by GTAW/SMAW/GMAW with Ni-base or matching high-Ni filler (e.g. ERNiCr-3 / Alloy 82 type); keep heat input low, no preheat, interpass below ~150 °C, avoid excessive dilution to limit hot cracking.
What surface finishes work on 1.4877?
Pickle and passivate or grind/blast to remove high-temperature scale before service; can be electropolished, but it is not anodizable and rarely plated.
Can 1.4877 be formed, bent or molded?
Hot work at 1150–950 °C then solution anneal; cold forming is possible but the alloy work-hardens rapidly so allow extra power, generous radii and intermediate annealing at 1050–1120 °C.
What is the maximum service temperature of 1.4877?
1.4877 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 1.4877-SA and 1.4877-CW?
SA is the default condition — standard delivery condition for tube, plate and bar: maximum ductility, homogeneous austenite with Nb carbides in solution/finely dispersed. CW: only for room-temperature strength or spring-like stiffness in small sections; not for creep service, since cold work is lost above ~600 °C. Yield strength is 260 MPa in SA versus 550 MPa in CW.
How much does 1.4877 cost?
1.4877 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.
