| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
AnnealedDefault softened (typ. 780–850 °C, air cooled) | Use the standard softened delivery condition (typically 780–850 °C, air cooled) for furnace structures and heat-resistant plate or strip serving up to 1150 °C. | 330 | 580 | 18 | 195 HB | 1.6 % IACS |

What is 1.4762?
1.4762 (X10CrAlSi25) is the highest-chromium member of the Fe-Cr-Al-Si heat-resisting ferritic family, at 25% Cr with aluminium and silicon additions for an adherent alumina scale. It gives the best oxidation resistance in the series for continuous use to about 1150 °C and is stocked as annealed sheet (1D, 2B), annealed bar and tube, and cold-drawn bar at 330 MPa yield, 580 MPa tensile, 18% elongation and 195 HB (92 HRB). Cold ductility is limited, room-temperature toughness falls sharply after high-temperature exposure, and machinability is low (40). 1.4742 covers 1000 °C duty at a lower alloy content. 1.4762 has a density of 7.15 g/cm³ (0.258 lb/in³), lighter than 100% of stainless steel grades. It melts at 1,450°C (2,642 °F). 1.4762 has a yield strength of 330 MPa (47.9 ksi) and a tensile strength of 580 MPa (84.1 ksi) — weaker than 57% of stainless steel grades.

Working with 1.4762
Is 1.4762 easy to machine?
Machinable but sticky with pronounced work hardening: use sharp positive-rake tooling, low speed with heavy feed, rigid clamping and ample coolant; coated carbide inserts are preferred.
Can 1.4762 be welded?
TIG, MIG and stick welding are all usable with low heat input and no or light preheat (100–200 °C); matching or Ni-base filler such as ER310 or ERNiCr-3 is recommended. Grain coarsening in the weld and HAZ markedly reduces room-temperature toughness.
Can 1.4762 be formed, bent or molded?
Cold formability is limited (bend radius ≥2t, avoid deep drawing); warm work thick sections at 150–300 °C. Hot work 1100→800 °C then slow-cool or anneal, and avoid long holds in the 400–550 °C range (475 °C embrittlement).
1.4762 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.

What surface finishes work on 1.4762?
Not anodisable; pickle and passivate, or shot blast and pre-oxidise at temperature to form the protective scale. It can be ground and polished but is hard and gummy, and paint or plating gives no benefit at service temperature.

1.4762 — frequently asked
What is 1.4762 used for?
1.4762 is typically used for furnace conveyor parts, radiant tubes, burner components and kiln furniture. In short: 1150 °C continuous service; best oxidation resistance in series; low room-temperature toughness.
What is the yield strength of 1.4762?
1.4762 has a typical yield strength of 330 MPa (47.9 ksi) and a tensile strength of 580 MPa (84.1 ksi) — weaker than 57% of stainless steel grades. Strength varies by condition: see the 2 listed tempers.
Is 1.4762 easy to machine?
Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Machinable but sticky with pronounced work hardening: use sharp positive-rake tooling, low speed with heavy feed, rigid clamping and ample coolant; coated carbide inserts are preferred.
Can 1.4762 be welded?
With care — weldability is rated fair (35/100). TIG, MIG and stick welding are all usable with low heat input and no or light preheat (100–200 °C); matching or Ni-base filler such as ER310 or ERNiCr-3 is recommended. Grain coarsening in the weld and HAZ markedly reduces room-temperature toughness.
What surface finishes work on 1.4762?
Not anodisable; pickle and passivate, or shot blast and pre-oxidise at temperature to form the protective scale. It can be ground and polished but is hard and gummy, and paint or plating gives no benefit at service temperature.
Can 1.4762 be formed, bent or molded?
Cold formability is limited (bend radius ≥2t, avoid deep drawing); warm work thick sections at 150–300 °C. Hot work 1100→800 °C then slow-cool or anneal, and avoid long holds in the 400–550 °C range (475 °C embrittlement).
What is the maximum service temperature of 1.4762?
1.4762 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 1.4762 Annealed and 1.4762-CD?
Annealed is the default condition — use the standard softened delivery condition (typically 780–850 °C, air cooled) for furnace structures and heat-resistant plate or strip serving up to 1150 °C. CD: choose as-drawn small-diameter bar and wire when 500 MPa yield and tight dimensional tolerance are needed; work hardening cuts elongation to 12% and lowers toughness. Yield strength is 330 MPa in Annealed versus 500 MPa in CD.
