Product Overview
Incoloy 800 (UNS N08800 / W.Nr. 1.4876) is a specialized nickel-iron-chromium solid round alloy specifically optimized for high-temperature structural and heating applications. The high chromium content forms a dense, self-healing protective oxide scale that delivers exceptional oxidation resistant performance during continuous and cyclic thermal operations up to 1100°C (2010°F). Combined with a balanced nickel composition, this solid round rod resists carburization, sulfidation, and internal oxidation in aggressive furnace atmospheres.
Our solid round rods with diameters from 16mm to 200mm undergo specialized vacuum induction melting (VIM) and electroslag remelting (ESR), followed by precision hot forging, hot rolling, and centerless grinding. This manufacturing rigor ensures uniform metallurgical grain structure, zero internal shrinkage, and superior mechanical machinability for demanding industrial heating element fabrication.
Key Technical Characteristics: Oxidation Resistant Properties
-
Superior Oxidation Resistance up to 1100°C
Forms a dense, self-healing chromia oxide film that eliminates surface scaling, flaking, and degradation during prolonged high-temperature exposure. -
Carburization & Corrosion Resistance
High-nickel matrix prevents carbon ingress and "green rot" embrittlement in aggressive furnace atmospheres and reducing environments. -
High Creep & Rupture Strength
Optimized metallurgical composition delivers high tensile strength at elevated temperatures, resisting thermal sagging, bending, and structural distortion. -
Thermal Shock & Fatigue Stability
Uniform internal grain structure withstands rapid, cyclic heating and cooling without micro-cracking or localized failure. -
Precision Machinability (h9/h11 Tolerance)
Centerless ground surface with tight diameter tolerances and superior straightness for seamless CNC turning, threading, and heating element assembly.

Frequently Asked Questions
Q1: Why choose Incoloy 800 over stainless steel for heating elements?
A: Unlike standard stainless steels that scale and sag above 800°C, Incoloy 800 forms a self-healing oxidation resistant chromia layer, maintaining structural integrity up to 1100°C.
Q2: What diameter range and custom sizes do you supply?
A: Standard stock covers Dia 16mm to 200mm. Custom micro-bars (<16mm) and forged billets (up to 350mm) are available upon request.
Q3: How does DLX guarantee internal material quality?
A: Every rod undergoes Electroslag Remelting (ESR) and 100% Ultrasonic Testing (UT Class A) to ensure zero internal voids, inclusions, or micro-cracks.
Q4: What surface finishes and tolerances are available?
A: We provide bright turned, polished, and centerless ground finishes with precision tolerances to h9/h11 and surface roughness down to .
Q5: What are your MOQ and delivery capabilities?
A: Standard stock MOQ starts from 50–100 kg with fast dispatch. Custom production batches ship in 15–25 business days, backed by our 1,200 tons/month capacity.
