TECHNICAL INFORMATION

Technical Specifications

Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.

Chemical Composition

ASTM B408 holds nickel between 30.0% and 35.0% and chromium between 19.0% and 23.0% for this round rod, with iron as the balance of the melt. Moreover, the carbon window and the Al+Ti total decide whether a heat reads N08800, N08810 or N08811. Besides, all three designations sit on one and the same B408 composition table.

For the full three-column element set, open the composition breakdown held on the Incoloy 800/800H/800HT material page for this round rod.

Mechanical Properties

The minimum room-temperature values below follow the rod and bar table of ASTM B408, split by delivery condition and designation. Consequently, condition and designation govern final acceptance of Incoloy 800/800H/800HT round rod.

Condition and Grade Tensile Strength, min. Yield Strength (0.2%), min. Elongation, min.
Hot-worked, as-hot-worked — UNS N08800 ≥80 ksi (550 MPa) ≥35 ksi (240 MPa) 25%
Cold-worked and hot-worked, annealed — UNS N08800 ≥75 ksi (515 MPa) ≥30 ksi (205 MPa) 30%
Annealed — UNS N08810 / N08811 ≥65 ksi (450 MPa) ≥25 ksi (170 MPa) 30%
  • Grade 800 keeps the higher room-temperature minimums because its anneal sets a finer grain, while 800H and 800HT trade part of that strength for the coarse grain their creep design needs, so the ordered designation and condition govern final acceptance.

Physical Properties

Published references place this round rod at a density near 7.94 g/cm³ with a melting range of 1357–1385 °C. Moreover, the Curie temperature sits near −115 °C, so this round rod stays non-magnetic in service. Besides, the austenitic matrix keeps these values stable across all three designations.

Meanwhile, the physical properties table on the Incoloy 800/800H/800HT material page holds the modulus, the thermal expansion and the remaining design values behind this round rod.

Heat Treatment

The anneal is the specification-defining step for this family, because the grain it sets decides the creep life of the part. In addition, we supply this Incoloy 800/800H/800HT round rod in whichever condition your duty calls for.

Condition Typical Treatment
Solution Annealed (800H) Held at 1121 °C (2050 °F) minimum, then cooled to set ASTM 5 or coarser grain
Solution Annealed (800HT) Held at 1149 °C (2100 °F) minimum for the 0.85–1.20% Al+Ti window
Grade 800 Anneal Annealed without a grain-size requirement, keeping the higher room-temperature strength
Stress Relieved A low-temperature relief that holds straightness without dwelling in the 425–815 °C sensitization band

Standards

ASTM B408 is the principal rod and bar document for this round rod, published by ASTM International, and its scope runs across five UNS numbers rather than the 800 series alone. Moreover, ASME SB408 covers pressure equipment, while SAE AMS 5766 reaches only the grade 800 chemistry. Besides, DIN 17752 and BS 3076 NA15 serve European and British orders for this round rod.

Standard Product or Application
ASTM B408 Nickel-iron-chromium rod and bar, UNS N08800, N08810, N08811
ASME SB408 ASME counterpart for pressure equipment

Custom Round Rod To drawing Custom

Available sizes of this Incoloy 800/800H/800HT round rod depend on the manufacturing route, the standard, the material condition and the order quantity. Please confirm your required round rod size, section and length in the inquiry.

Surface Finishes

Finish decides how this round rod scales, machines and clears your incoming checks, and 800H and 800HT normally ship solution annealed so the coarse grain survives to the end of the route. Specifically, we fix the finish on this Incoloy 800/800H/800HT round rod before the order is released.

Surface Condition Typical Use
Cold Drawn Drawn stock giving this round rod close diameter control and a smooth bright skin.
Centreless Ground Ground diameter and straightness on this round rod for shafts and spindles.
Bright Annealed Protective-atmosphere annealing leaves this round rod oxide-free and ready to draw.

Meanwhile, the surface finishes table on the Incoloy 800/800H/800HT material page lists the remaining conditions we quote for this round rod.

FAQ

Frequently Asked Questions

Which standard covers this Incoloy 800/800H/800HT round rod?

ASTM B408 and ASME SB408 govern this Incoloy 800/800H/800HT round rod across the three designations for round, square, hex and rectangular sections.

Which designation should I order for service above 593 °C?

ASTM B408 names 1100 °F (593 °C) as the ceiling for normal service of UNS N08800, so creep-governed duty above that line moves to 800H or 800HT for this Incoloy 800/800H/800HT round rod.

What does the coarse-grain requirement change on this Incoloy 800/800H/800HT round rod?

The 800H and 800HT anneals set ASTM 5 or coarser grain, so this Incoloy 800/800H/800HT round rod ships with an E112 record rather than a fine annealed structure.

Does AMS 5766 cover all three designations?

No. AMS 5766 reaches bars, forgings and forging stock of the grade 800 chemistry only, so 800H and 800HT orders for this Incoloy 800/800H/800HT round rod follow the ASTM and European documents.

How is the price of this Incoloy 800/800H/800HT round rod calculated?
