1.4986 / X7CrNiMoBNb16-16+QT

Alloy 1.4986 / X7NiCrMoNb34-9-1 – High-Strength Austenitic Stainless Steel for High-Temperature Applications

Engineered for extreme thermal and mechanical stress, Alloy 1.4986 offers superior creep resistance, oxidation stability, and mechanical strength at elevated temperatures. Commonly used in energy, power generation, and petrochemical industries.

Rolled, solution annealed, age hardened, straightened
(Designed to meet elevated-temperature creep and fatigue resistance requirements)

• Tensile Strength (Rm): min. 950–1,100 MPa

• Yield Strength (Rp0.2): min. 600–850 MPa

• Elongation: min. 15–20%

• Hardness: typically 270–330 HBW (depending on heat treatment)

• Operating Temperature Range: up to 700–750 °C

Used in:
High-temperature bolting, steam turbine components, pressure vessels, heat exchangers, and critical fasteners in power plants and petrochemical environments

Spec:
DIN EN 10269 (1.4986), VdTÜV 421, AD 2000-Merkblatt W10, ASME Section II (for elevated-temperature components)
