HSMetal Inconel 600 Rods (UNS N06600 / W.Nr. 2.4816 / NiCr15Fe) are high-performance nickel-chromium-iron alloy bars designed for sustained performance under extreme conditions. As a member of the Inconel® family of nickel-based superalloys, Alloy 600 delivers an exceptional combination of high strength, excellent oxidation resistance, and outstanding corrosion resistance across a broad temperature range – from cryogenic conditions up to 1093°C (2000°F) in continuous service.
The alloy's solid-solution strengthened austenitic microstructure, with a minimum nickel content of 72%, provides both thermal stability and resistance to chloride-ion stress-corrosion cracking – a combination that makes Inconel 600 rods the preferred choice for critical applications in aerospace, petrochemical, nuclear, and power generation industries.

Corrosion Resistance
Inconel 600 offers outstanding resistance across a wide spectrum of corrosive environments:
| Environment | Performance |
|---|---|
| Chloride Stress-Corrosion Cracking | Excellent – nickel content >72% provides stability even at >1000 ppm Cl⁻, 93‑316°C |
| High-Temperature Oxidation | Excellent – stable Cr₂O₃ scale up to 1093°C |
| Caustic Alkalis (NaOH, KOH) | Excellent – classic material for caustic evaporators |
| High-Purity Water | Excellent |
| Organic Acids | Excellent |
| Carburising Atmospheres | Good – superior to 300 series stainless steels |
| Dry Chlorine & HCl | Good – up to ~540°C |
Limitations: The alloy contains no molybdenum or niobium, so resistance to pitting and crevice corrosion is limited. It is not recommended for seawater stagnation, high-chloride crevice conditions, or concentrated hydrochloric/sulfuric acids. Sensitisation may occur after prolonged exposure at 550‑850°C – 600H variant is available for high-temperature creep applications.

Q1: What are Inconel 600 Rods mainly used for?
A: HSMetal Inconel 600 Rods (UNS N06600) are nickel‑chromium‑iron alloy rod stock for machining aerospace engine hot‑section parts and petrochemical high‑temperature furnace & reactor components. It offers excellent oxidation and chloride stress‑corrosion resistance for high‑temperature service.
Q2: What standards apply to Inconel 600 Rods?
A: Primary standard is ASTM B166 for rods and bars; AMS 5687 for aerospace‑grade requirements. Material designation UNS N06600 / W.Nr.2.4816.
Q3: Does Inconel 600 require post‑weld heat treatment?
A: Normally post‑weld heat treatment is not mandatory for Inconel 600. It supports TIG, MIG and other common welding methods, weld joints retain good corrosion‑resistant performance.
Q4: What test documents can you supply for Inconel 600 Rods?
A: We provide EN 10204‑3.1 MTR, PMI positive material identification report, mechanical test report and third‑party inspection documents for tender submission.
Q5: What specifications does HSMetal Inconel 600 Rod meet?
A:Our Inconel 600 rods are manufactured to ASTM B166 / ASME SB166, AMS 5665, BS 3076 NA14, and comply with NACE MR0175 / ISO 15156 for sour‑service applications. Full mill test reports and COA accompany every shipment.
Q6: What sizes and forms are available?
A:We supply round rods in custom diameters, as well as hexagonal, square, and flat bars upon request. Custom cutting, machining, and length tolerances are also available.
Q7: Is Inconel 600 rod easy to machine and weld?
A:Yes. Inconel 600 offers good machinability (similar to austenitic stainless steels) and is readily weldable by GTAW, GMAW, and SAW. No pre‑heat or post‑weld heat treatment is required for most applications. Use matching filler metal ERNiCr‑3 (Alloy 82) for optimal weld properties.
Q8: What are the typical applications for Inconel 600 rods?
A:Common uses include aerospace combustion chamber liners and turbine exhaust hardware, petrochemical reactors and heat exchangers, nuclear steam generator supports, and heat‑treating furnace components.
Q9: How does Inconel 600 compare with Inconel 625?
A:600 contains no molybdenum and is primarily used for high‑temperature oxidation (up to 1093°C) and caustic alkali resistance. 625 contains 8‑10% Mo and 3‑4% Nb, offering superior resistance to pitting, crevice corrosion, and chloride SCC. Use 600 for high‑heat and caustic environments; use 625 for seawater, sour‑gas, and chemical applications with chlorides.
Q10: How does Inconel 600 compare with Inconel 601?
A:601 contains a higher aluminium content (1‑1.7%) for enhanced scaling resistance up to 1180°C – making it the preferred choice for severe high‑temperature oxidation and carburisation. 600 offers better resistance to chloride SCC and is more cost‑effective. Use 601 for extreme heat; use 600 for balanced oxidation + corrosion resistance.
Q11: How does Inconel 600 compare with Alloy 800H?
A:800H is an iron‑nickel‑chromium alloy (Fe ~46%) designed for creep strength at elevated temperatures (800‑1000°C). 600 has higher nickel (≥72%) and better resistance to chloride SCC and reducing acids. Use 800H for high‑temperature creep applications; use 600 for corrosion‑priority environments.
Q12: Can I request samples before placing a bulk order?
A: Absolutely. We offer sample quantities for customer evaluation. Please let us know your required specifications (diameter, length, and surface condition), and we will arrange shipment promptly. For new customer we need you pay for the sample costs, as old customer sample costs are typically credited against your next bulk order.
Q13: What is the Minimum Order Quantity (MOQ)?
A: Normally MOQ is 200kg, We always expect more opportunities with you. But for some special material or special size let's communicate the actual status.
Q14: What is your lead time?
A: For standard sizes in stock, we ship within 10-15 working days. For custom sizes or normalized heat treatment, lead time is typically 30-40 working days (depending on specifications and quantity). We always provide a clear delivery schedule before order confirmation and strictly adhere to it.
Q15: What payment terms do you accept?
A: We accept T/T, L/C, and other common methods. For new customers, we usually require 50% deposit and 50% balance before shipment. Flexible terms can be negotiated for long-term partners
Q16: What if I find quality issues after receiving the goods?
A: We provide a 100% quality guarantee. If any non-conformity is found, please provide photos and test data within 7 working days of receipt. We will respond within 48 hours and agree on replacement, return, or compensation terms.
