Product Overview

What are Hastelloy C2000 Threaded Rods?

Hastelloy C2000 threaded rods are nickel-chromium-molybdenum-copper alloy fasteners manufactured from UNS N06200 bar stock conforming to ASTM B574. The alloy’s unique combination of chromium (22-24%), molybdenum (15-17%), and copper (1.5-2.5%) delivers outstanding resistance to both oxidizing and reducing corrosive media – a dual capability no other single nickel alloy achieves at this level.

With a PREN exceeding 55, Hastelloy C2000 threaded rods resist chloride-induced pitting, crevice corrosion, and stress corrosion cracking in aggressive process environments including sulfuric acid, hydrochloric acid, and mixed acid streams. These rods are specified for chemical reactor closures, flue gas scrubbers, and pharmaceutical process equipment where standard C-276 or 316L stainless fasteners fail prematurely.

Material Chemistry

Hastelloy C2000 Chemical Composition

Hastelloy C2000 Threaded Rods derive their exceptional acid corrosion resistance from a precisely controlled nickel-molybdenum-chromium composition per ASTM. High molybdenum and tungsten content suppresses pitting and reducing-acid attack; ultra-low carbon (0.01% max) eliminates sensitization risk in welded assemblies. Full elemental composition is certified in the EN 10204 MTC supplied with every Hastelloy C2000 threaded rods order from RealBolt.

Why Hastelloy C2000 Alloy Composition Matters for Threaded Rods

Mo (15–17%) — Superior Reducing Acid Resistance
The elevated molybdenum content gives Hastelloy C2000 exceptional resistance to reducing acids including hydrochloric and sulfuric acid across a wide concentration and temperature range — critical for threaded rod assemblies in chemical reactor closures and acid storage vessel flanges.
Cu (1.5–2.5%) — Dual Oxidizing/Reducing Protection
Copper is the defining addition that separates C2000 from C-276. It extends corrosion resistance into oxidizing acid environments such as dilute sulfuric acid with oxidizing contaminants, making C2000 threaded rods the preferred choice where process chemistry fluctuates between oxidizing and reducing conditions.
Ultra-Low Carbon (0.01% max) — Sensitization-Free
The extremely low carbon ceiling eliminates any risk of carbide precipitation at grain boundaries during welding or elevated-temperature service. Hastelloy C2000 threaded rods maintain full intergranular corrosion resistance in the as-welded condition without post-weld heat treatment.

?? 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 incompatibility accelerates thread corrosion.

Industry Applications

Hastelloy C2000 Threaded Rods Applications — Industries & End Uses

Hastelloy C2000 Threaded Rods from RealBolt are specified across chemical processing, pharmaceutical, oil and gas, and FGD where excellent corrosion resistance and 800 MPa tensile strength are required for reliable fastener performance. Click each industry below for detailed application examples.
Hastelloy C2000 threaded rods are the preferred fastener for chemical reactor closure flanges, agitator shaft assemblies, and pressure vessel nozzle connections handling sulfuric acid, hydrochloric acid, and mixed acid streams. The dual oxidizing/reducing corrosion resistance eliminates the need for two separate alloy grades across a single process train.
Threaded rod assemblies in pharmaceutical reactor vessels, CIP (clean-in-place) piping systems, and solvent handling equipment benefit from C2000’s ultra-low carbon content and smooth surface finish capability. Compliant with ASME BPE surface finish requirements and suitable for FDA-regulated process environments.
Hastelloy C2000 threaded rods are specified for FGD absorber tower internals, spray header supports, and duct expansion joint tie rods where wet HCl-bearing flue gas at elevated temperatures causes rapid corrosion of C-276 and duplex stainless steel fasteners. The higher chromium content of C2000 provides superior oxidizing acid resistance in this environment.
Threaded rod assemblies in chlorine dioxide bleaching towers, washer drum frames, and chemical mixing vessel covers require resistance to hypochlorite, chlorine dioxide, and acidic bleach filtrate. Hastelloy C2000 outperforms C-276 in oxidizing bleach environments due to its elevated chromium and copper additions.

Hastelloy C2000 Threaded Rods — Frequently Asked Questions

Browse expert answers to common questions about Hastelloy C2000 Threaded Rods from RealBolt — covering acid corrosion resistance, NACE MR0175 compliance, ASTM standards, available sizes, and MTC documentation. Contact our technical team directly for project-specific guidance on Hastelloy C2000 threaded rods selection and pricing.
Hastelloy C2000 threaded rods are manufactured to DIN 975 (fully threaded rod in standard 1m and 2m lengths), DIN 976 (double-end stud configuration), and ISO 888 for metric thread forms. Inch-series rods are produced per ASME B18.31.3 in UNC and UNF thread forms. Custom lengths up to 6000mm are available in metric sizes, and special thread forms including BSW, BSPP, and Whitworth can be produced with a 15 working day lead time. All rods are supplied with thread tolerance class 6g per ISO 965.
Hastelloy C2000 offers superior performance in oxidizing acid environments compared to C-276, due to its higher chromium content (22-24% vs 14-16%) and the addition of copper (1.5-2.5%). In purely reducing acid service, both alloys perform similarly. C2000 is the preferred choice when process chemistry alternates between oxidizing and reducing conditions, or where dilute sulfuric acid with oxidizing contaminants is present. For pure HCl or strongly reducing environments, C-276 remains a cost-effective alternative. Consult our engineering team for a corrosion data comparison specific to your process stream.
Always use nickel-based anti-seize such as Molykote P-37, Jet-Lube KOPR-KOTE Pure Nickel, or Bostik Never-Seez Pure Nickel Special. Apply to the full thread length and nut bearing faces before assembly. Reduce target torque values by approximately 20% compared to dry assembly values. Never use copper-based, zinc-based, or graphite anti-seize on Hastelloy C2000 – galvanic incompatibility between copper or zinc and the nickel-rich alloy can initiate accelerated corrosion at thread contact points, particularly in wet or acidic service.
Yes – Hastelloy C2000 threaded rods comply with NACE MR0175 / ISO 15156 for sour (H2S-containing) service when supplied in the annealed condition with hardness not exceeding 35 HRC. The alloy’s nickel-chromium-molybdenum composition provides resistance to sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC) in wet H2S environments. Hardness survey reports per NACE MR0175 requirements are available on request for each production lot.
