Product Overview

What are Hastelloy C2000 Studs?

Hastelloy C2000 studs 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 exceptional resistance to both oxidizing and reducing acid environments – a dual capability no other single nickel alloy achieves at this level.

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

Material Chemistry

Hastelloy C2000 Chemical Composition

Hastelloy C2000 Studs 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 studs order from RealBolt.

Why Hastelloy C2000 Alloy Composition Matters for Studs

Mo (15–17%) + Cr (22–24%) — Dual Oxidizing/Reducing Resistance
The high molybdenum content provides outstanding resistance to reducing acids such as hydrochloric and sulfuric acid, while the elevated chromium level simultaneously protects against oxidizing media including nitric acid and ferric chloride. No other single nickel alloy covers both attack modes as effectively in stud bolt applications.
Cu (1.5–2.5%) — Sulfuric Acid Performance
Copper additions significantly improve corrosion resistance in dilute and intermediate concentrations of sulfuric acid — a critical advantage for stud bolts used in chemical reactor flanges and acid plant heat exchanger covers where H2SO4 concentrations fluctuate between 10% and 70%.
Ultra-Low Carbon (0.01% max) — Sensitization-Free Welding
The extremely low carbon ceiling prevents carbide precipitation at grain boundaries during welding or elevated-temperature service. Hastelloy C2000 studs welded into assemblies retain full corrosion resistance in the heat-affected zone without any post-weld heat treatment requirement.

?? 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 Studs Applications — Industries & End Uses

Hastelloy C2000 Studs 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. Select an industry below to see specific Hastelloy C2000 studs application details and RealBolt stock availability.
Hastelloy C2000 stud bolt sets are the preferred specification for reactor closure flanges, column nozzle connections, and heat exchanger channel covers in plants handling sulfuric acid, hydrochloric acid, and mixed oxidizing/reducing acid streams. The alloy’s dual-environment resistance eliminates the need for separate fastener grades across different process zones.
Stud bolts for sterile reactor vessels, agitator flange connections, and high-purity process piping where contamination from corrosion products is unacceptable. Hastelloy C2000 studs meet FDA material traceability requirements and resist the aggressive cleaning agents – including hot nitric/phosphoric acid blends – used in CIP cycles.
Flange stud bolt sets for FGD absorber inlet ducts, mist eliminator supports, and recirculation pump nozzles where saturated HCl-bearing flue gas at 50-80°C creates severe crevice corrosion conditions under bolt heads. C2000 outperforms C-276 in this environment due to its higher chromium content providing superior oxidizing acid resistance.
Stud bolts for chlorine dioxide bleaching stage equipment, washer drum flanges, and filtrate line connections. The combination of high molybdenum and copper in C2000 provides resistance to hypochlorite, chlorine dioxide, and acidic chloride solutions that rapidly attack duplex stainless and even C-276 fasteners in high-temperature bleach plant service.

Hastelloy C2000 Studs — Frequently Asked Questions

Browse expert answers to common questions about Hastelloy C2000 Studs 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 studs selection and pricing.
Hastelloy C2000 studs are manufactured to DIN 976-1 (metric fully threaded studs), DIN 939 (studs with metal-end engagement length), ASME B18.31.2 (continuous and double-end studs, inch), and ASME B16.5 / B16.47 for flange stud bolt sets in Class 150 through Class 2500. Custom configurations including tap-end studs, stud bolts with reduced shanks, and non-standard thread forms (BSW, BSF, BSPP) are available with 15 working day lead time.
Hastelloy C2000 (UNS N06200) offers superior performance to C-276 (UNS N10276) in oxidizing acid environments due to its higher chromium content (22-24% vs 14.5-16.5%). In reducing acid service, both alloys perform comparably. The addition of copper (1.5-2.5%) in C2000 provides a specific advantage in sulfuric acid at intermediate concentrations (10-70% H2SO4). For mixed acid environments or processes that alternate between oxidizing and reducing conditions, C2000 studs are the technically superior and more cost-effective single-alloy solution.
Yes – Hastelloy C2000 studs supplied in the annealed condition with hardness not exceeding 35 HRC comply with NACE MR0175/ISO 15156 for use in H2S-containing sour service environments. All production lots are hardness-surveyed per NACE requirements. Certificates confirming compliance are included with the EN 10204 3.1 MTC as standard. For Class 900 and above sour service flange stud bolt sets, a full hardness survey report is provided covering both studs and mating heavy hex nuts.
Standard metric sizes M12 through M36 and common ASME B16.5 flange stud bolt sets are held ex-stock with no formal minimum order quantity – single-piece supply is available for emergency maintenance and shutdown requirements. Custom sizes and non-standard configurations carry a minimum of 10 kg per order. ASME B16.5 flange stud bolt sets are quoted and supplied by the complete set with no piece-count minimum. Volume price breaks apply at 25 kg, 100 kg, and 500 kg.
