Incoloy 800H Pipe Fittings Specifications

Published Incoloy 800H fitting specifications commonly identify ASTM B366 / ASME SB366, with ASME B16.9, MSS SP-43 and ASME B16.11 used for applicable dimensions and fitting configurations.

Incoloy 800H Chemical Composition

The chemistry of Incoloy 800H is designed around a nickel-iron-chromium base with controlled carbon, aluminium and titanium levels.

The controlled carbon and Al+Ti ranges are important characteristics of 800H. They help distinguish it from standard Alloy 800 and support its elevated-temperature creep and stress-rupture performance.

Incoloy 800H Mechanical Properties

Mechanical properties depend on the product specification, product form and material condition. Representative solution-annealed minimum values commonly specified for Incoloy 800H include approximately 65 ksi (450 MPa) tensile strength, 25 ksi (170 MPa) yield strength and 30% elongation.

Final mechanical requirements should always be checked against the governing ASTM/ASME specification and the supplied product condition.

Why Choose Incoloy 800H Pipe Fittings?

High-Temperature Strength

The primary advantage of 800H over standard Alloy 800 is improved performance for sustained high-temperature service. Controlled chemistry and grain-size requirements help improve creep and stress-rupture resistance.

Creep Resistance

Creep becomes increasingly important when a piping component remains under mechanical stress for long periods at elevated temperature. Incoloy 800H is specifically used where improved creep performance is required.

Stress-Rupture Resistance

800H is designed for high-temperature structural applications where resistance to stress rupture is an important engineering consideration.

Oxidation Resistance

The chromium-containing chemistry provides strong resistance to oxidation at elevated temperatures.

Carburization Resistance

Incoloy 800H is used in high-temperature process environments where carburization can affect conventional materials. It is particularly relevant to petrochemical and thermal-processing equipment.

Structural Stability

The alloy is designed for prolonged high-temperature service where dimensional and metallurgical stability are important.
