Product Overview

What are Inconel 600 Screws?

Inconel 600 screws are nickel-chromium alloy fasteners manufactured from UNS N06600 bar stock conforming to ASTM B166. The alloy’s high nickel content (72% min) combined with chromium (14-17%) delivers exceptional resistance to oxidation, carburisation, and chloride-induced stress corrosion cracking across a broad temperature range from cryogenic conditions up to 1175°C.

Inconel 600 screws are specified under ASTM F468 for high-temperature furnace assemblies, chemical processing equipment, and nuclear reactor components where standard austenitic stainless steel fasteners fail prematurely. The alloy’s immunity to chloride stress corrosion cracking makes it a preferred choice for marine and petrochemical environments where 316L screws are inadequate.

Material Chemistry

Inconel 600 Chemical Composition

Inconel 600 Screws are manufactured from a nickel-chromium superalloy containing nickel (72% min), chromium (14–17%), and iron (6–10%). Each element is precisely controlled per ASTM — nickel provides chloride SCC immunity, chromium drives high-temperature oxidation resistance, and iron balances structural stability and alloy cost.

Chemical Composition per ASTM B166

ElementComposition (%)
Nickel (Ni)72.0% min
Chromium (Cr)14.0-17.0%
Iron (Fe)6.0-10.0%
Carbon (C)0.15% max
Manganese (Mn)1.0% max
Silicon (Si)0.50% max
Copper (Cu)0.50% max
Sulphur (S)0.015% max
? All heats verified by NABL-accredited spectrometry. PMI available on request.

Why Inconel 600 Alloy Composition Matters for Screws

Ni (72% min) — Chloride SCC Immunity
The high nickel base of Inconel 600 provides complete immunity to chloride-induced stress corrosion cracking — the primary failure mode of 304 and 316 stainless steel screws in hot aqueous chloride environments such as nuclear reactor coolant circuits and marine heat exchangers.
Cr (14–17%) — High-Temperature Oxidation Resistance
Chromium forms a stable, adherent oxide scale that protects Inconel 600 screws from oxidation and carburisation up to 1175°C. This makes the alloy the standard choice for furnace fixture screws, retort fasteners, and heat treatment basket hardware where thermal cycling is continuous.
Fe (6–10%) — Structural Stability
The controlled iron content stabilises the austenitic matrix and contributes to the alloy's resistance to nitriding atmospheres. Inconel 600 screws maintain dimensional integrity and thread engagement in ammonia-bearing process environments where iron-free nickel alloys would be over-specified.

?? Anti-galling: Use nickel-based anti-seize (Molykote P-37 or Bostik Never-Seez Pure Nickel). Lubricated values assume K=0.15. Never use copper-based anti-seize on nickel alloys - galvanic corrosion risk.

Industry Applications

Inconel 600 Screws Applications — Industries & End Uses

Inconel 600 Screws from RealBolt are specified across oil and gas, aerospace, chemical processing, and power generation where excellent corrosion resistance and 760 MPa tensile strength are required for reliable fastener performance. Click each industry below for detailed application examples.
Inconel 600 screws are the standard fastener for industrial furnace fixtures, retort assemblies, heat treatment baskets, and muffle furnace internals. The alloy resists oxidation and carburisation at continuous service temperatures up to 1175°C, outperforming 310 stainless steel screws in cyclic thermal environments where repeated expansion and contraction loosen conventional fasteners.
Inconel 600 screws are specified for pressurised water reactor (PWR) steam generator tube sheet connections, reactor vessel internals, and control rod drive mechanism hardware. The alloy’s immunity to chloride stress corrosion cracking in high-purity water at elevated temperature and pressure makes it the material of choice per ASME Section III nuclear code requirements.
Machine screws and hex screws for reactor vessel covers, heat exchanger channel closures, and agitator shaft assemblies in caustic soda, organic acid, and mixed alkali environments. Inconel 600 resists both oxidising and reducing conditions, making it suitable across a wider pH range than any standard stainless steel grade.
Inconel 600 screws are used in aircraft engine nacelle fastening, combustion chamber liner attachment, and exhaust collector ring assemblies where oxidation resistance above 900°C and resistance to thermal fatigue are simultaneously required. Manufactured to AMS 5540 specification for aerospace-critical applications.

Inconel 600 screws are manufactured to DIN 933 (hex full thread), DIN 912 (socket head cap), ISO 4017, ISO 4762, and ASME B18.6.3 (inch machine screws). Socket head cap screws are also available per ASME B18.3 for inch dimensions. Special drive types including Torx, Phillips, and slotted heads are available on request. Custom thread forms including BSW and UNF are produced with a 15 working day lead time.
Yes – Inconel 600 is one of the most widely specified alloys for continuous high-temperature service. The alloy resists oxidation up to 1175°C in air and maintains adequate mechanical strength for furnace fixture and retort fastener applications up to approximately 900°C. It also resists carburisation and nitriding atmospheres, making it suitable for case-hardening furnace internals where carbon pickup would embrittle stainless steel screws.
Yes – Inconel 600 (UNS N06600) has a long history of use in nuclear reactor internals, particularly in pressurised water reactor steam generators and control rod drive mechanisms. The alloy is specified under ASME Section III for nuclear pressure boundary components. Note that in certain high-temperature, high-purity water environments, Inconel 600 can be susceptible to primary water stress corrosion cracking (PWSCC) at sustained temperatures above 300°C – consult your engineering team for specific reactor coolant circuit applications.
Inconel 600 screws can be used continuously up to 1175°C in oxidising atmospheres and up to 1040°C in reducing or mixed atmospheres. In cyclic thermal service, the practical upper limit is typically 1050°C to avoid excessive grain growth. For applications above 980°C requiring higher strength retention, consider Inconel 601 or Inconel 625 as alternatives. All temperature limits assume annealed condition material per ASTM B166.
